My son is almost 13 months old now and doesn't really drink any water (or anything other than breastmilk from the breast). I've tried giving him a sippy cup and regular open plastic cup and he thinks they make wonderful projectiles. He used to play with a cup in the bath and sometimes try drinking water from it, but he hasn't cared for it lately and closes his mouth if I try to hold the cup up to his mouth. (This doesn't surprise me because he's more willing to self-feed than to be assisted with it.) Is it time for him to be drinking water? His solid intake varies a bit, but he's easily taking most of his nutrition from breastmilk still. Should I get a different kind of sippy cup, like one with a straw? I've heard that some people like the zoli cup.
How many wet diapers should he be making at this point?
