Re: water in sippy cup at 4 1/2 mon.
I introduced the sippy cup because he won't take a bottle and won't nurse that well anymore. I am just letting him figure it out right now with a little bit of water. I started solids because he is 4 1/2 mon. and he weighs 17 lbs. He can't handle his vitamins( :( they make him throw up). He does real well with it and he has lost his tongue thrust reflex. He dosen't even make a mess with the cereal. It was the only way I thought to make sure that he is getting all of his vitamins and nutrition. I mix the cereal with BM.
