I BF T after every meal and in between. I don't see much of a point in using a sippy since he gets all of his liquids from me, but I would like for him to learn how to use one. He's not too keen on water (he'll take two sips from a bottle and abandon the rest) and I can't and don't want to give him juice. I definitely don't have enough milk to pump and put in a sippy. Lol
