When is it okay to start giving your
baby whole milk?
When your baby is 12 months old, he or she can start to drink whole-fat
cow's milk. Other kinds of milk, such as goat's milk, fat-free milk, 1% milk, or 2%
milk, don't have as many nutrients as whole-fat milk. It is best not to give
your baby these kinds of milk if you can give whole-fat milk instead.
