I know that if you're giving cow milk to a child under 2 as a drink to children under 2 it should be whole milk. Is there something inherently bad about reduced fat milk? My husband and son like to share a bowl of mini-wheats for breakfast. We adults drink 2%, so that's what's on the cereal. Little man gets plenty of full fat yogurt and cheese, and he still nurses 3-4 times a day. When he doesn't eat cereal with 2% he eats toast or oatmeal and applesauce. So is there a strong reason to insist on whole milk?
