My two-year old LOVES his "ba-ba" too. And, I wish I had weened him off of it when he was young enough to not have cared. Regardless, he only drinks out of it before nap and bedtime. I asked my pediatrician if there would be any problems with his teeth and such, and he said it was fine as long as my son didn't sleep with a bottle of milk in his mouth as it can cause tooth decay. He thought there was nothing to worry about especially since my son drinks out of a cup, straw, sippy, etc the rest of the time. And, it's not like my son is going to be drinking out of a bottle in elementary school...hopefully :-). Besides, it makes all of our lives more peaceful and happy by giving our son his 'ba-ba' to calm him down before bed.
