Breastfeeding is not binary.

–This post is part of our 10-year anniversary series “Breastfeeding is…” When we initially curated this series, we planned for 10 weeks, but breastfeeding is so many things that we just couldn’t fit it all in.  Thus, two bonus weeks in our anniversary series! — 

Breastfeeding is not binary.

There’s solid evidence that direct breastfeeding offers the most protective and beneficial effects to mothers, babies and ultimately society.

When breastfeeding, a baby’s saliva transfers chemicals to their mother’s body that causes her milk to adjust to meet the changing needs of the baby. [Al-Shehri, et al 2015]

Even more fascinating, the combination of baby saliva and fresh breastmilk generates enough hydrogen peroxide to inhibit growth of Staphylococcus and Salmonella. Read about the science behind it all here.

Breastfeeding encourages proper mouth and jaw development and promotes oral health. 

When babies breastfeed, they are less likely to become obese for reasons like self-regulation of milk intake and seeding of their gut microbiomes. [Pérez-Escamilla, 2016] 

Infants at the breast, compared to bottle-fed infants, have better heart and respiratory rates and higher oxygen saturation rates because breastfeeding consumes less energy.

Breastfeeding has implications on mother-infant bonding and children’s future behavior. One study found that “compared to children whose mothers breastfed them, children who were not breastfed showed an increased number of internalizing behavioral problems, particularly anxious/depressed and somatic symptoms… A duration effect (dosage effect) appeared such that breastfeeding for 10 months or longer had the strongest impact on reducing anxious/depressed and somatic symptoms in children.”

Direct breastfeeding does not require feeding paraphernalia that may be vectors for disease. 

Even if the contents of a bottle contain human milk, the effects achieved through direct breastfeeding may not be possible.  

However, the reality of families’ lives, and sometimes choice, mean that most babies in the U.S. will not exclusively breastfeed or go on to breastfeed in conjunction with appropriate complementary feeding as recommended.

The most recent CDC Breastfeeding Report Card acknowledges, “Numerous barriers to breastfeeding remain, and disparities persist in breastfeeding duration and exclusivity rates by race, ethnicity, and socioeconomic status. Policy, systems, and environmental changes that address breastfeeding barriers, such as better maternity care practices, paid leave policies, and supportive ECE centers, can help to improve breastfeeding rates and reduce disparities.” 

For these reasons and others, infant feeding often takes many forms. Infant feeding in America is not either/or, it’s both/and

Fiona Jardine and Aiden Farrow present experiences that do not fit into how we often generalize the infant feeding experience. 

Universal pumping icon by Fiona Jardine

Jardine’s work follows those who exclusively pump human milk. Farrow too pumped milk for their child born with cleft complications and then went on to directly chestfeed their baby.

Farrow has explained: “Feeding methods are not mutually exclusive. There are always windows and doors.” 

Lactation care providers, other care providers, health policies and procedures must all acknowledge the incredibly diverse experiences of families while honoring the very ubiquitous human desire that we all want what’s best for our babies.

Colorado pediatric office becomes breastfeeding friendly employer

Castle Rock Pediatrics (CRP) made a splash this summer at the Douglas County Fair Parade where they displayed their incredible Under the Sea themed float. Patients and families created a colorful array of paper plate fish that “swam” through pool noodle crafted seaweed.

CRP also attended the  Renaissance Expeditionary Magnet School Back to School Carnival and the Downtown Castle Rock Concert Under the Lights where they set up a lactation station.

After breastfeeding her own young children and later completing the Lactation Counselor Training Course (LCTC), Laura Westover PA-C, CLC, one of the providers at CRP, dove into helping transform her office into a Breastfeeding-Friendly Employer and soon-to-be Breastfeeding- Friendly Medical Office.

Their work is supported by a grant through the Tri-County Health Department. Westover has been working alongside Susan Howk, a breastfeeding policy specialist, to create their policies and lactation spaces through a six-point plan which includes policy, staff and provider training, patient education, environment, evaluation and sustainability, and continuity of care.

The grant has funded things like a chair, end tables, a hospital-grade multi user breast pump and kits, a stuffed animal nursing dog with her puppies for siblings to play with, and a lactation scale for weighted feeds.

Westover displays the breastfeeding friendly employer certificate in March 2022 standing in their first lactation space.

Their lactation space started in one of their smallest exam rooms, but has recently graduated to one of their larger exam rooms, which is now near the end of its renovation. Westover notes that the space also functions for newborn and young baby visits.

Westover reports that CRP owners since November 2021 Drs. Anderson and Bouchillon have been highly supportive of the breastfeeding-friendly changes.

Prior to the implementation of their lactation policies, Westover says their office “was not lactation friendly at all.” She describes stacks of formula in plain view.

“It gave the impression that we were promoting formula,” she comments.

Gift bags for patients were also riddled with formula-promotions, so the team phased out the branded materials and replaced them for non-branded, breastfeeding-friendly items.

Now, Westover and her colleague Sydney Gruenhaupt RN-BSN, CLC  see breastfeeding dyads weekly for office visits; whereas they once had to refer out. Of mothers’ main concerns are poor weight gain and uncomfortable or painful latch.

Westover points out that Colorado has very high breastfeeding initiation rates, but like the national trend, tapers dramatically at 6 months and beyond. While Westover and her colleagues are not currently tracking their office’s breastfeeding rates, it’s part of the plan in hopes that their numbers will hold steady beyond initiation rates. Westover explains since they’ve switched over to a larger electronic medical records system, there should be potential for a simple, infant feeding tracking system. A 2016 project by the County of San Diego Healthy Works program, implemented by UC San Diego Center for Community Health with funding from First 5 San Diego extensively explores current practices and future possibilities of  breastfeeding measurement in the outpatient electronic health record.

Westover and her colleagues will be out and about again this fall where they’ll craft their  lactation tent at events like Oktoberfest and the town of Castle Rock Spooktacular Halloween celebration.

“[It’s] really wonderful because we are able to promote [to] the whole community,” Westover shares.

Empathy in architecture

A friend of mine works in a healthcare building; her office, windowless. Stark white walls frame the shiny tiled floors in the also windowless laboratory that surrounds her office. Rectangular fluorescent lighting looms eerily overhead. Working in this space for the majority of her waking hours amounts to constant longing for sunshine and an overall agitated demeanor. I imagine the architect of this space wasn’t much of an empath.

Photo by Robert Katzki on Unsplash

This effect is being documented in a growing body of research demonstrating how color, texture and patterns affect human emotions.

Generally, humans are quite robot-like, performing our daily duties without a great deal of attention paid to the building structures, layouts or designs that we move through. 

“When we don’t notice the built environment, it’s silently affirming our right to be there, our value to society. When we do, too often it is because it’s telling us we don’t belong. Those messages can be so subtle that we don’t recognize them for what they are,” Kim Tingley writes, later quoting architect Joel Sanders: “‘We sleepwalk our way through the world…Unless a building interior is strikingly different or lavish or unusual, we are unaware of it.’” 

The first time I saw a lactation pod at an airport– unusual at the time– I had mixed emotions. Part of me became excited that this was an option for traveling, lactating, pumping, and breastfeeding people, but most of me scoffed, annoyed, thinking something along the lines of: “Of course breastfeeding moms would be given this messaging to go hide themselves away from the public eye.” 

What Tingley wrote, that our built environment affirms our right to be in a space, affirms our value to society, is certainly a powerful concept. 

The COVID pandemic has forced us to think more about the built spaces we move through, adding layers to this idea of how and what and who we value.  

In a recent episode of Uniquely Milwaukee Salam Fatayer of 88Nine Radio Milwaukee poses the question: “What could our city, neighborhoods and community spaces look like if they were created based on people’s emotional, psychological and social needs?”

Local architects and scholars answer with ideas about how they’re supporting the users of the spaces they create, with the goal of making sure people feel safe, at peace and nurtured by those built environments. 

On Our Milky Way, we’ve had the honor of highlighting the work of those thinking about how built spaces affect birth, lactation and beyond. 

For example, in conjunction with the Institute of Patient-Centered Design, Inc., The MomFriendly Network created The Lactation Design program which consists of research and outreach projects to enable the Institute to contribute design resources that  improve accommodations to support breastfeeding. Read more about this project here: https://www.ourmilkyway.org/physical-environment-influences-breastfeeding-outcomes/ 

Renée Flacking and her colleagues’ work, Closeness and separation in neonatal intensive care, explores how architecture influences outcomes in neonatal units. Single-family room designs are increasingly replacing traditional open-bay units for reasons documented in their paper.

Source: United States Breastfeeding Committee (USBC)

“This architectural structure provides the family with an opportunity to be with their child in the neonatal intensive care unit day and night providing facilities for parents’ basic needs including the need for privacy. This design has been suggested to be associated with a lower rate of hospital-acquired infections, similar to single patient rooms in adult intensive care (48), earlier full enteral nutrition, higher breastfeeding rates and a more soothing environment with, for example, lower ambient sound levels (49). As this design has been shown to reduce the length of stay in hospital significantly, for example, by 10 days in preterm infant below 30 weeks of gestation in a Swedish study (50), it shortens the time of separation for the infant from the home and family. Parents have reported that they felt that a single family room design in a NICU facilitated their presence with their infant (51), but the increase in parent–infant closeness gained by a single family room model during hospital care is not well documented in scientific literature.”

Read Our Milky Way’s coverage on this concept here

In stark contrast, attorney Leah Margulies recently shared in Protecting Breastfeeding in the United States: Time for Action on The Code that formula companies provide architectural designs to maternity care facilities in a deliberate attempt to separate dyads, making bonding and breastfeeding difficult and consequently,  families more likely to become reliant on their artificial products. It’s a sickening example of how the industry saturates our systems, down to the skeletons of our buildings.

Venturing beyond the very early postpartum period, it’s exciting to explore how community spaces are supporting young families. The Henrico County Public Library – Fairfield Area Library is accommodating families with their Computer Work + Play Stations which were conceptualized by library staff and materialized by architects at Quinn Evans and TMC Furniture staff.

Supporting lactation and breastfeeding in the workplace is a vital part of ensuring that lactating individuals feel valued. Setting up lactation spaces sometimes calls for innovation and creativity. You can explore our collection of stories about workplace accommodations in the stories below:

Pulling back the lens further, the architecture of communities themselves influences well-being too. One of the effects of redlining is poor health outcomes. Part of this equation involves the placement of industrial buildings and factories. Vann R. Newkirk II points out in Trump’s EPA Concludes Environmental Racism Is Real that The National Center for Environmental Assessment released a study indicating that BIPOC are much more likely to live near polluters and breathe polluted air. “Specifically, the study finds that people in poverty are exposed to more fine particulate matter than people living above poverty,” he writes.  

NICHQ hosts a webinar The Residual Impact of Historical Structural Inequities: Connecting Residential Segregation and Mortgage Discrimination to Current Infant Mortality and Breastfeeding Rates where maternal child health experts including speakers Jaye Clement, MPH, MPP, Brittney Francis, MPH, Kiddada Green, MAT, Arthur James, MD and Jessica Roach, LPN, BA, MPH share examples for supporting efforts to reduce infant mortality and improve maternal and infant health. 

Circling back to Tingley’s piece, the article raises the concern that although we’re equipped with knowledge about how under-resourced populations are being affected by current structures and practices,  “funding earmarked for expanding inclusivity [may] be diverted toward making existing facilities safer for those they already privilege.” 

Drawing on Sanders’ work, Tingley writes,  “Throughout history… the built environment has reflected and reinforced inequality by physically separating one group from another, often in the presumed interests of health or safety. Women-only bathrooms, so designated by men, supposedly preserved their innocence and chastity; white-only bathrooms separated their users from supposedly less ‘clean’ black people. It’s no coincidence that Covid-19 has disproportionately sickened and killed members of demographic groups — people who are black, Indigenous and Latino; who are homeless; who are immigrants — that have been targets of systemic segregation that increased their vulnerability. It’s also not hard to imagine the pandemic, and a person’s relative risk of infection, being used to justify new versions of these discriminatory practices.”

In this vein, Glenn Gamboa details where some funding gets funneled in a piece published this spring. 

“Twelve national environmental grant makers awarded $1.34 billion to organizations in the Gulf and Midwest regions in 2016 and 2017, according to a 2020 study by The New School’s Tishman Environment and Design Center. But only about 1% of it — roughly $18 million — was awarded to groups that are dedicated to environmental justice.” 

The climate crisis is an accelerating threat that is both affected by and affects architecture. 

“Architecture has to mediate between the perceived needs of the moment versus the unknowable needs of the future; between the immediate needs of our bodies and the desire to create something that will outlast generations,” Tingley goes on to write. 

Across the globe, architects push to be “mindful of their projects’ environmental impacts and resilience, including an emphasis on upcycling, the use of solar power, better building practices, and, of course, structural longevity,” Alyssa Giacobbe writes.  [More on ecological design here.] 

Alongside resilience and sustainability, there must be a focus on design that specifically serves mothers and their children. Mothers are too often left out, unseen, underserved despite there being about two billion of us worldwide, with an increasing likelihood of women becoming mothers

Lisa Wong Macabasco puts it this way: “Although the experience of human reproduction touches all of us at least once in our lives, its effects remain taboo, under-researched and excluded from exhibitions and publications covering architecture and design history and practice. In these spheres, maternity is treated furtively or as unimportant, even as it defines the everyday experiences of many – some 6 million Americans are pregnant at any given time.” 

It isn’t surprising that “design for children, design for healthy spaces, design for those with disabilities, care of and for their colleagues – these discussions and follow through are happening largely through female-led firms and initiatives,”  Julia Gamolina comments in The Unspoken Burden on Women in Architecture

In an exciting development, Wong Macabasco describes design historians Amber Winick and Michelle Millar Fisher’s Designing Motherhood, “a first-of-its-kind exploration of the arc of human reproduction through the lens of design. Their endeavor encompasses a book, a series of exhibitions and public programs in Philadelphia, and a design curriculum taught at the University of Pennsylvania.” 

This is exciting, and it’s progress. But as Wong Macabasco quotes Juliana Rowen Barton– architecture and design historian and curator who also helped organize Designing Motherhood– “Progress is not the fact that this show happened – progress is these conversations continuing to happen.” 

Designing Motherhood is on view at the Mutter Museum in Philadelphia through this month of May 2022.

Musings on unity beyond National Breastfeeding Month

This year’s National Breastfeeding Month (NBM) celebration has come to an end, but our momentum as maternal child health advocates– striving for equitable care for all– powers on. 

The 2020 NBM theme, Many Voices United, called on us to come together to identify and implement the policy and system changes that are needed to ensure that all families have the support and resources they need in order to feed their babies healthily.

Achieving this shared goal requires daily self-work and individual introspection so that our collective can be as effective as ever. No matter how socially-conscious, open-minded, anti-racist, (insert adjective), we think we may be, we still have learned biases and prejudices that require near constant attention. Much like I remind my children to brush their teeth every morning and every night, as a white, binary woman, I must remind myself to examine my biases and my privilege daily.  

With NBM’s theme of unity in mind, this Upworthy video features an art installation that demonstrates our society’s interconnectedness. With a piece of string, the installation shows an intricate, densely-woven web created by individuals wrapping thread around 32 poles with identifiers arranged in a circle. 

“You can see that even though we all have different experiences and we all identify in different ways…We are really one,” the project’s creator says in the video. 

The sentiment and the product are truly beautiful and fascinating. While appreciating the beauty of unity, it’s important to keep our critical thinking and progressive attitude sharp, refraining from slipping into too comfortable a space where change cannot happen.  

Recently, I’ve seen a few statements on unity circulating social media that I’d like to embrace with a “Yes!” Instead, I find myself reacting, “Yes! But…” 

My worry is that these well-intentioned mantras we live by– much like some might argue certain microaggressions are well-intentioned– are also dismissive. 

  1. We all bleed the same blood. 
  1. Children are not born racist.
  1. I will teach my child to love your child. Period. 

Let’s break those down starting with “We all bleed the same blood.”  Some things to consider:

First, Ashley May for The Thirbly writes,

“Black breasts do not exist separate from Black bodies and the situated existence we navigate in this world nor the racialized experience of motherhood. Racism and classism intertwine to act as a containment, working to make some of us feel as if we are walking in quicksand. Add to this the complexities of new motherhood and the needs of the postpartum body and now we have a cocktail for failure. Literal milk plugs. So, although her precious body may be able to produce milk, her situation prevents her and her baby from receiving it. Even the intention to breastfeed cannot save the milk of the mother who cannot find time for pump breaks as she works the night shift as a security guard. Or, perhaps she cannot figure out why pumping is not working, but she doesn’t have the time to seek the educational or financial resources to help her problem solve.” (underline added by OMW) 

Racism affects People of Color (POC) at a cellular level. Studies show that the experience of racial discrimination accelerates the shortening of telomeres (the repetitive sequences of DNA at the ends of chromosomes that protect the cell) and ultimately contributes to an increase in people’s risks of developing diseases. 

It’s epigenetics; the environments POC of are growing in affect their biology.  

Children are not born racist, but white children are born into a racist society that they will benefit from. 

From the very beginning, white children have a better chance of survival than Children of Color; African Americans have 2.3 times the infant mortality rate as non-Hispanic whites

What’s more, Black children are three times more likely to die when cared for by white doctors, while the mortality rate for white babies is largely unaffected by the doctor’s race, a recent study found. 

White children are born into being part of the problem and just the same, can be part of equitable solutions. 

I will teach my child to love your child. Period. 

Love is action, and even if it’s easier said than done, there are so many ways to teach our children about race, inequities and injustice. Afterall, “If Black children are ‘old enough’ to experience racism then white children are ‘old enough’ to learn about it.” – Blair Amadeus Imani

  • Be careful what you say. As a young girl on my way to ballet class one day, my mom, while locking the car doors,  pointed out the barred doors and boarded windows in the neighborhood we rolled through. 

“That’s how you know this is not a safe neighborhood,” my mom warned me. 

No questions asked, I noted the building facades, and then I noted the Black people. Because there wasn’t any further conversation, I made the connection that Black people must be “not safe” and ultimately, that there must be something wrong with Black people if they’re confined to neighborhoods “like this.” 

Imagine the impact we could make if we showed our children that there is nothing inherently wrong with Black people that ending racism can’t solve.

As a nation we are apathetic, made apparent by a recent poll. The survey shows that only 30 percent of white people have taken concrete action to better understand racial issues after George Floyd’s killing. 

The poll also shows that White Americans are also the least likely to support the Black Lives Matter movement, with 47 percent expressing support.

Is it because we don’t claim it as our problem? Is it because we misunderstand the problem? Is it because it’s easier to point fingers at others than ourselves? 

I’d like to leave you with this video of writer Kimberly Jones where she provides a brief history of the American economy told through an analogy using the board game Monopoly. I urge you to watch it, and then watch it again, and again, and again. 

There is no time for complacency within these truly abhorrent systems. When we start to lose sight of that, envision the tangle of yarn from the aforementioned unity art installation and remember that vastly different experiences are networked together.

Breastfeeding and the environment: Guest post for World Breastfeeding Week 2020

By Donna Walls, RN, BSN, ICCE, IBCLC, ANLC

Each year the World Alliance for Breastfeeding Advocacy (WABA) chooses a theme for World Breastfeeding Week (WBW) celebrations around the world. WBW is celebrated every year during the first week in August. This year’s theme is “Support Breastfeeding for a Healthier Planet”. 

The 2020 objectives are:

  • Inform people about the links between breastfeeding and the environment/climate change
  • Anchor breastfeeding as a climate-smart decision
  • Engage people and organizations for greater impact
  • Galvanize action on improving the health of the planet and people through breastfeeding

Can breastfeeding really affect climate change and create a cleaner, healthier environment? 

Our planet’s health is closely tied to human health, and so there is a growing interest in learning how to protect the health of the environment. 

Among the many things humans can do to protect the environment, breastfeeding is one of the most important. Breastfeeding is the best example of a clean, eco-friendly action to protect and improve the health of planet Earth. 

Breastfeeding is the ultimate natural, sustainable resource. It requires no raw materials needed for processing and no energy consumption in production or transportation. It does not produce any material waste or by-products, does not require any packaging materials, water resources or electricity, and creates no pollution of the air or water. Lactation is a perfect partner for environmental health and the ultimate example of “eating local”.

Parents who express their milk and feed from bottles or other methods also provide a more planet-friendly feeding method than artificial feeding. Formula manufacturing requires energy, material and transportation. 

The carbon footprint of breastfeeding gives us another glimpse into the environmental impact of breastfeeding. Wikipedia defines carbon footprint as “the total greenhouse gas emissions caused by an individual, event, organization, service, or product, expressed as carbon dioxide equivalent.” In simple terms, it’s a measurement that shows us something’s impact  on the health of the environment. 

The carbon footprint of breastfeeding is based on the production and transportation of food for the mother based on the RDA of an additional 500 kcal/day recommended during breastfeeding. According to research from the United Kingdom, the carbon footprint of breastfeeding is estimated at 5.9 (this varies between countries). 

In comparison, the carbon footprint of formula feeding— which is based on the use of resources, animal and factory production emissions and transportation of the formula as well as supplies, preparation and storage of formula at home— is estimated at 11.0 (again varying between countries). On average, feeding breast milk substitutes had a higher impact on the climate than breastfeeding in all countries studied. This certainly demonstrates the positive impact on the environment when the infant feeding choice is breastfeeding.(Bodkin, 2019 Meade, 2008)

The International Baby Food Action Network (IBFAN) supports optimal infant feeding practices and  advocates for universal implementation of the International Code of Marketing of Breastmilk Substitutes, an international health strategy recommending restrictions on the marketing of all formulas and supplies intended to discourage breastfeeding. In 2015 IBFAN developed their statement on breastfeeding and the environment:

“Breastfeeding protects our health and our planet – right from the start, breastfeeding is the first step towards protecting human health, short- and long-term. It is also the first step towards protecting the health of our environment and conserving our planet’s scarce natural resources. We need to start at the beginning, with infants and young children. Our babies and children are in no way responsible for climate change and environmental degradation, but instead they suffer the disastrous consequences.” (IBFAN, 2015)

 It’s clear that breastfeeding is the most climate-friendly option for infant feeding, but does the environment have an impact on breastfeeding? The answer is yes. 

For decades scientists around the world have studied the impact of environmental contaminants on the mammary gland, and on mothering behaviors. For instance, a study from the Journal of Health Science demonstrated that rats exposed to dietary bisphenol A (BPA) in early pregnancy showed cellular injury to the mammary glands as well as lower prolactin levels. (Miyaura, 2004). 

What’s more, Rochester Medical Center studies reported in Science Daily demonstrated damage to rat mammary glands to the extent that some mother rats were unable to nourish their pups after exposure to dioxins. Researchers noted that some rats were able to recover mammary function by late pregnancy. (Lawrence, 2009). 

In 2013, a study in the Journal of Neurotoxicology and Teratology showed a decrease in maternal behaviors in Wistar rats (less grooming, protection and nuzzling), a concerning finding but not yet demonstrated in humans. (Boudalia, 2013}.

Studies like these are the basis for ongoing research looking into possible negative impacts on human lactation. The studies are also the basis of much education related to how to create a safer environment while protecting lactation.  

An unpublished study from Wright State University looked at mothers with self-described low milk supply and the relationship between environmental contaminants. The 78 mothers in the study were four  weeks to eight  months postpartum and were all given education on reducing exposures to environmental estrogens (personal care products, food hormones and plasticizers). 

Results were seen in one to five weeks and ranged from the mothers stating her “breasts were fuller,” the “babies seemed more satisfied,” and fewer needed supplementation. Some found a doubling of supply (noted with pumping during work hours). Seven had no noticeable increase in milk supply, and of those only two weaned from breastfeeding. The rest continued supplementation. (Walls, presented 2009). 

In a Mexican study of young Yaqui tribe women, those who moved from native land  to new chemical based agriculture, had less alveolar tissue compared to the young women who remained with the tribe and practiced  traditional, non-chemical farming techniques. 

Many of the agri-chemical exposed young women were found to have larger than normal breasts, but less glandular tissue (referred to as “empty breast” syndrome) and many were unable to breastfeed their infants which is viewed as an integral part of mothering in their culture. (Hansen, 2010).

On the surface, these studies can seem discouraging until we really weigh the risks and benefits of breastfeeding in a polluted world. 

First, human milk contains properties that have been shown to mitigate some negative, environmental effects. (Williams, Florence, NYT) 

For instance, human milk contains bio-active components which specifically control and resolve inflammation, promote a thick, healthy gut lining to support an optimum functioning immune system and provide the most nutritious food for optimum general health for infants and children.  

Emeritus Director of the Carolina Global Breastfeeding Institute Miriam Labbok, MD, MPH, IBCLC stated “The fact that studies of child [health] outcomes in highly polluted areas are still better for the breastfed infant . . . would seem to indicate that certain factors in the production of human milk and in the milk itself, immunological and other, may mediate the potential harm of the ambient pollution.”

She went on to say, “… No environmental contaminant, except in situations of acute poisoning, has been found to cause more harm to infants than does lack of breast-feeding. I have seen no data that would argue against breastfeeding, even in the presence of today’s levels of environmental toxicants.”

Sandra Steingraber, biologist and author of Living Downstream and Having Faith: An Ecologist’s Journey to Motherhood agrees: ”We haven’t yet compromised breast milk to such an extent that it’s a worse food than infant formula…..”

The American Academy of Family Physicians (AAFP) has also published that certain components of human milk act to increase the infant’s elimination of some toxins and to protect the infant’s developing brain, central nervous system, and body as a whole.

WABA’s statement  on breastfeeding and environmental contaminants echoes this sentiment and  encourages breastfeeding as the safest feeding choice despite maternal exposure to contaminants. 

Their statement reads: “Is the presence of these chemical residues in breastmilk a reason not to breastfeed? No. Exposure before and during pregnancy is a greater risk to the fetus. The existence of chemical residues in breastmilk is not a reason for limiting breastfeeding. In fact, it is a reason to breastfeed because breastmilk contains substances that help the child develop a stronger immune system and gives protection against environmental pollutants and pathogens. Breastfeeding can help limit the damage caused by fetal exposure.” (WABA, 2005.)

The World Health Organization’s (WHO) review on contaminants and human milk states definitively, “The benefits of breastfeeding far outweigh the toxicological disadvantages that are associated with certain POPs” (persistent organic pollutants). 

To reiterate, considering the safety of human milk even when contaminants have been detected, neonatal intensive care researcher Fani Anatolitou (2012) states, “the detection of any environmental chemical in breast milk does not necessarily mean that there is a serious health risk for breastfed infants. No adverse effect has been clinically or epidemiologically demonstrated as being associated solely with consumption of human milk containing background levels of environmental chemicals”. 

It is important to understand that many of the measurements of POPs in human milk are not clinically meaningful, hence are not a cause for alarm. Even more importantly, as mentioned earlier, a number of components of human milk act to counter potential risks of contaminant exposure (Anitolitou, 2012). The Centers for Disease Control and Prevention (CDC) points out that effects of exposure have only been detected in a breastfeeding infant when the mother was extremely ill.

As lactation care providers we are in a unique position to not only support the optimum health of infants and children, but also be a part of creating a healthier environment for the children to grow and thrive.
