My 12 month old son is still waking up in the middle of the night to have a bottle. My question is does that causes tooth decay or is it bad for him at this age to still wake up and want a bottle? I am a first time mom so I’m not really sure so out of reaction I get up and make his bottle and I fed him and he is off back to sleep l... I’m not sure if this is OK or should I just give him water to make him fall back to sleep maybe he’s thirsty not too hungry. He screams as if he is super hungry so I fed him the bottle but he has a nice meal before bed time. No bottle so he can get off of it but he still wants it the bottle
