E.P.
Well, the fact that he knows you will pour it back into a bottle (if he just lets it sit long enough) probably is not really helping the situation. You know, my Mom always said children will not starve themselves or go thirsty by choice. So, he just needs to learn the bottle is no longer an option. It has become more of a comfort thing for him at this point instead of a something he has to have to enable him to drink....since you know he will drink out of a cup at a caregiver's home. Just give him his milk in a sippy cup....maybe find some fun ones that he will enjoy using. But, you need to get rid of the bottle now, or it will only continue. He may cry at first, but, he will survive....really! And about heating the milk....I was not heating my children's milk at your son's age. That'll make you life easier too! Good luck!.....by the way, I had both of my sons off their bottle by the age of one...it really is easier the earlier you do it!!!!
