It sounds like something straight out of a Victorian novel or a period piece on Netflix, doesn't it? You picture a somber woman in a stiff apron holding a royal baby while the biological mother looks on from a distance. But honestly, when we talk about whats wet nursing, we’re looking at one of the oldest professions in human history—and a practice that is quietly resurfacing in very modern ways.
Wet nursing is the act of a woman breastfeeding a child that is not her own.
It’s basic biology. If a mother couldn't produce milk, or if she passed away during childbirth, the infant needed a food source to survive. Before the invention of reliable infant formula in the mid-19th century, there weren't many options. You either found another lactating woman, or you took a massive gamble with "dry nursing" (feeding the baby animal milk or pap), which often ended in tragedy.
The Brutal and Beautiful History of the Wet Nurse
For thousands of years, this was the norm. In Ancient Egypt, wet nurses were highly respected. They were so vital that the Code of Hammurabi even had specific laws regulating their work. It wasn't just a job; it was a life-saving necessity.
But it’s also complicated.
During the 18th century in Europe, wet nursing became a status symbol for the wealthy. Aristocratic women often viewed breastfeeding as "low class" or physically draining. They would send their infants away to the countryside to live with a wet nurse for years. It was a business. Unfortunately, this led to "baby farming," where some women took on too many infants to make more money, leading to neglect.
There's a darker side in American history, too. Enslaved Black women were frequently forced to wet nurse the children of their white enslavers, often at the expense of their own children's nutrition and bond. You can't talk about whats wet nursing in a Western context without acknowledging that for centuries, it was often rooted in exploitation and systemic inequality.

Why Do People Still Do It?
You might think formula solved this.
For the most part, it did. Modern formula is a miracle of science that allows babies to thrive when breastfeeding isn't an option. Yet, in the last decade, there’s been a shift. Whether it’s due to the "fed is best" vs. "breast is best" debates or the massive formula shortages we saw in 2022, parents are looking at human milk sharing again.
Sometimes it’s about health.
In Neonatal Intensive Care Units (NICUs), "wet nursing" has evolved into formalized milk banking. Premature babies are incredibly susceptible to a dangerous gut condition called Necrotizing Enterocolitis (NEC). Research, including studies published in journals like Pediatrics, consistently shows that donor human milk significantly reduces the risk of NEC compared to formula for these fragile infants.
Then there’s the "cross-nursing" phenomenon. This is the casual, unpaid version. Imagine two best friends who are both lactating; one goes to a doctor's appointment, and the other feeds both babies. It’s communal. It’s tribal.
The Safety Reality Check
We have to get real for a second about the risks. While the idea of a "community milk supply" sounds lovely and pastoral, it’s not without danger.

Human milk can transmit diseases. We're talking HIV, HTLV, syphilis, and Hepatitis B or C. Beyond viruses, there’s the issue of medications and lifestyle choices. If a woman is taking certain prescriptions or using substances, those can pass through the milk to the baby.
This is why medical organizations like the American Academy of Pediatrics (AAP) and the FDA generally discourage informal milk sharing. They worry about the lack of screening. If you’re getting milk from a stranger on a Facebook group, you don't actually know their medical history, no matter how nice their profile picture looks.
Formal Milk Banks vs. Informal Sharing
When you're trying to figure out whats wet nursing in the 2020s, you'll see two distinct paths:
- HMBANA Banks: The Human Milk Banking Association of North America. These are the gold standard. They recruit donors, test their blood, and pasteurize the milk to kill bacteria and viruses while keeping most of the nutritional benefits intact. It’s expensive, and usually, the milk is reserved for the sickest babies in hospitals.
- Peer-to-Peer Sharing: Groups like Eats on Feets or Human Milk 4 Human Babies. These are grassroots. There’s no money exchanged (selling breast milk is a whole different, legally murky area). It’s based on trust and "informed choice." Parents meet, discuss health histories, and share milk.
The Psychological Impact
It's not just about the calories.
Breastfeeding involves a complex hormonal dance. Oxytocin—the "love hormone"—is released during let-down. For some wet nurses, this creates a profound emotional bond with the child. For others, it’s strictly a job or a gift.
In some cultures, particularly in Islamic tradition, wet nursing creates a "milk kinship." A child fed by a wet nurse is considered a "milk sibling" to the woman's biological children. This bond is so strong that it carries legal and social weight, including specific rules regarding marriage later in life. It shows that whats wet nursing is as much a social construct as it is a biological one.

Is It Right for You?
If you're considering this, you've got a lot to weigh.
Maybe you can't produce enough milk due to a medical condition like IGT (Insufficient Glandular Tissue) or a previous mastectomy. Maybe you’re an adoptive parent or a generic father in a same-sex couple who wants your child to have the immunological benefits of human milk. These are all valid reasons to explore the world of donor milk.
But you have to be the CEO of your baby's health.
Don't be afraid to ask for blood test results. Don't feel "rude" for asking a potential donor about their alcohol consumption or if they’ve traveled to areas with specific endemic diseases. A legitimate donor will understand. They want the baby to be safe too.
Practical Steps for Those Seeking Donor Milk
If you've decided that formula isn't the primary route you want to take, here is how you handle the process safely:
- Talk to a Lactation Consultant: Find an IBCLC (International Board Certified Lactation Consultant). They are the pros. They can help you determine if your supply issues can be fixed or if donor milk is truly necessary.
- Prioritize Screened Sources: Your first stop should always be a non-profit milk bank. Check if your insurance covers it, especially if your baby has a medical need.
- Use the "Four Pillars" of Safe Sharing: If you go the peer-to-peer route, follow the guidelines established by advocates: informed choice, donor screening, safe handling, and home pasteurization (the Flash-Heat method is a common recommendation for killing most pathogens at home).
- Check the Legalities: In some jurisdictions, selling breast milk is regulated or even illegal. Stick to altruistic sharing to avoid "for-profit" milk which often lacks the same safety incentives.
- Trust Your Gut: If a situation feels weird or a donor is hesitant to share health info, walk away. There are thousands of generous women out there who are happy to be transparent.
Wet nursing isn't a relic of the past. It's a living, breathing part of how humans care for their young. Whether it's through a high-tech lab or a neighborly hand-off, the goal remains the same: making sure the next generation gets exactly what it needs to grow.
Understanding the nuances of milk sharing allows you to move past the "weirdness" factor and see it for what it is—a unique, deeply human solution to a universal challenge. If you choose to explore this path, do it with your eyes wide open, your questions ready, and your baby’s safety as the absolute north star.
