Babies can start drinking whole cow's milk as their main drink after they turn 1 year old. The American Academy of Pediatrics and other health authorities recommend continuing breast milk or formula as the primary liquids until 12 months of age, after which whole milk can be introduced because it contains the fats essential for healthy brain development during the first two years of life
. It is also acceptable to offer small amounts of whole milk in a sippy cup starting around 11 months to help the baby get used to the taste and practice cup drinking, but it should not replace breast milk or formula before 12 months
. Whole milk is recommended until the child turns 2 years old, after which lower-fat milk options can be considered based on pediatric advice
. In summary:
- Under 12 months: Breast milk or formula only; cow's milk can be used in cooking or mixed with food but not as a main drink
- Around 11 months: Small sips of whole milk can be introduced to familiarize the baby with the taste
- After 12 months: Whole cow's milk can be given as the main drink, alongside solid foods and water
- Continue whole milk until age 2, then consult pediatrician about switching to lower-fat milk
This guidance ensures babies receive the appropriate nutrition and avoid risks such as iron deficiency associated with early introduction of cow's milk.
