When to Wean a Baby From Breastmilk to Cow's Milk?

Generally babies can begin drinking cow's milk after their first birthday. Although milk may be introduced at this age, weaning the baby completely from breast milk or formula may take some time.

When to Introduce Cow's Milk

The American Academy of Pediatrics advises against offering cow's milk to a child younger than 1 year to reduce risk of allergies and difficulty with digestion. In the first year, babies should only be fed breast milk, iron-fortified formula and age appropriate solid foods. After the child's first birthday, parents may begin transitioning their toddlers from breast milk or formula to cow's milk.

Making the Transition

According to Doctor Laura Jana, M.D, most babies will do well if their regular amount of breast milk or formula is completely substituted with cow's milk the first time it is offered. However, some babies may be reluctant to accept cow's milk. In these cases, parents should mix formula or breast milk with cow's milk and gradually decrease the amount of formula or breast milk until their baby is fully transitioned to cow's milk.

Special Considerations

The American Academy of Pediatrics advises parents to give their babies whole milk between 1 and 2 years of age. However, if there is a risk of obesity or heart disease in the family, parents should opt for 2% milk instead. Babies with milk allergies should drink soy milk or other substitutes, as advised by their pediatrician.
