The Case For Breastfeeding Toddlers

The Case For Breastfeeding Toddlers

Extended nursing

Nature Knows Best. Mothers in traditional societies breastfeed their children well into their toddler years, and there is good reason for it. The World Health Organization suggests exclusive breastfeeding for 6 months with continued breastfeeding for at least 2 years.  But, in the U.S., breastfeeding a baby past their first birthday is called extended breastfeeding, and it is not culturally accepted. New studies are proving that mothers who let their child decide when to quit nursing are helping their babies receive optimal mental and physical health.

Dr. Katy Dettwyler, anthropologist and breast feeding advocate, studied 64 traditional societies and found that their median age for weaning was 2.8 years.  Her research shows that many tribal communities wean between three and four years of age and often much older. Such communities practice child-led weaning, or let the child decide when they no long need the breast.

Child-led weaning is becoming more popular in the US, but women who practice “extended” breastfeeding often hide it from others to spare themselves ridicule. There is a growing population of women who are turning to nature for child rearing advice. Such women trust their gut, listen to their babies, and study the benefits of things like breastfeeding.

Formula does not exist in nature, and most babies have a gag-reflex until at least 12 months of age which keeps them from being able to eat foods that aren’t pureed and made into baby food. Nature’s food is breast milk, and a breast milk meets all of a baby’s nutritional needs.

The 2-4 year age range for natural weaning is fascinating in conjunction with new scientific studies that show that the brain and the gut continue to develop well into the third year of life and breastfeeding during this time is crucial for brain and gut development. Studies show that the gut-brain development within the first few years of life reflect the health of a person throughout adulthood.

Filled with healthy fats, vitamins and minerals, breast milk is the perfect food to build the cellular components of the gut and brain and to provide fuel for their optimal functioning.  But, there is much more to breast milk that has been overlooked until now. The no-longer-secret ingredient necessary for gut and brain development— the reason that extended breastfeeding is so important is– MICROBES! 

Microbes are always competing with each other for food and space. The food a person eats feeds the microbes within their body, and different strains of microbes feed upon different things. In addition to containing more than 700 types of microbes, breast milk also contains simple sugars that feed specific kinds of beneficial, gut-seeding microbes. 

In a recent experiment, Vicky Greene, a biosciences student at South Devon College, did an experiment where breast milk samples from mothers with babies ages 15 month and 3 years were cultured with bacteria M. Luteus. In all 9 samples, the bacteria did not grow near the breast milk because the breast milk fought off the colonization of the bacteria. This experiment showed that not only is breast milk a powerful antibiotic, but that the antimicrobial properties of breast milk continue into the toddler years when the gut microbiome is still in critical formation. 

Breast milk contains microbes, probiotics, prebiotics and antibiotics all at once! Breast milk has properties so remarkably complex that it can in no way be mimicked. Breast milk is needed, not just preferred, by babies well into their toddler years.

Breast milk has a very high concentration of white blood cells, the immune system’s soldiers in the battle against pathogens. The composition of breast milk changes depending on what the mother’s nipple perceives that the child needs after contact with the child’s saliva. This customizable feature of breast milk is apparent in premature babies and toddlers alike.  

Science has only recently been able to see the tip of the iceberg on how the gut and brain influence each other, but it is known that there is a causal relationship between breastfeeding and mental health and cognitive development. Scientists are theorizing that the seeding of the gut microbiome may be the most important factor in this relationship.  Scientists studying autism have started looking at the guts of children, and their findings are giving additional weight to the case for  “extended” breastfeeding. 

Many women hate nursing toddlers, but people accuse women of doing so for selfish reasons.  Toddlers fuss, they have teeth, and they become demanding, and frankly, women are sick and tired of having their nipples stretched, scratched, bitten, and twiddled. Many moms are ready to wean way before their child is ready, but they put their child’s needs before their own.

A breastfeeding mom is a mom who sacrifices. She sacrifices her body, her time, and her social life. She suffers persecution for being a nurturing mother.

There is no need to call breast feeding past the age of 1 “extended.” It is not an excess, and it is arguably the best thing a mother can do for the health of her child. It is hard and frustrating to nurse a toddler, and mothers who breastfeed should be supported and not ridiculed. 

Note: The author acknowledges that there are additional benefits to nursing a child until they are ready to wean that are not covered in this post.


  1. Currently experiencing toddler feeding (hadn’t planned to but it’s actually easier to keep going than stop) and the range of responses from tolerant to disapproving. Majority are influenced by old beliefs and lack of knowledge- I’m interested and I didn’t even know all benefits, thanks for information! Adding that to my prepared responses!😉

  2. I totally agree. I know most mothers would breastfeed longer if: 1) our culture would accept it; 2) if they did not have to go back to work; 3) if they were healthy enough to not have to take medication daily; 4) if they had a strong, loving, sacrificial conviction to put their child before their own needs or wants. But the main thing, I think, is cultural. If everyone is doing it & it is accepted, then most mothers would do it too.

    • Thank you! I agree that the major hurdle is the American culture. If there was ever an agenda to teach Americans to have an aversion to nature, it seems to have worked.
