G.K.
My son never took milk (mine or cow's) from a bottle OR sippy cup. He was breastfed and wouldn't drink from anything but the boob! We tried every kind of milk until his pediatrician told me to let it go, that humans are the only mammals that drink milk that's not their own. Now, I love milk, but it makes total sense. Well, I didn't push it, and he finally started drinking milk on his cereal, but he still isn't a big milk drinker, and he's 3 1/2. He drinks plenty of water, though!
