I really didn't have any advice to offer but wanted to let you know that you are not alone! My 22 month old son drinks and then either spits it or lets it all dribble down the front of his shirt and thinks it is hilarious! I don't understand it but we take his cup and he can't have it back until its been about 10 minutes. He's usually done playing by then and just wants to drink it.
