Wasn't sure what thread to put this under... My son is 2.7 years old. He has his bottle first thing in the morning, nap time, bed time and when he's upset. I know he's using it as a comforter but what age is good age to take it off them? It feels like every week I'm buying new bottles because ds keeps biting the teats. Would you just go cold turkey and take them away full stop?
