We recommend only breastmilk or formula before the age of 1 because these are the most nutritionally dense options. But after a year of age, our goal is for our toddlers to get the majority of their nutrition from solid food. 

Cow’s milk is a good source of fat and protein, but those are relatively easy to make up with other foods. The calcium and vitamin D, on the other hand, may require more thought.

Many children transition to cow’s milk around a year of age. Cow’s milk provides a number of essential nutrients, which are important for healthy bones and teeth, immunity, brain development and growth. Like most things, moderation is key. Too much cow’s milk can also lead to health issues.
