My 1 year old loves his bottle dearly, it is his source of comfort. He knows how to drink from a sippy cup, but there are days where all hell breaks loose if he does not get his bottle. He will cry bloody murder and throw his sippy cup until he gets his bottle. I try to not give into him, but after 20 minutes of crying, I give him a bottle so he won't make himself throw up. Also, he prefers to go to sleep with a bottle and will wake up if he does not have it, I am trying to put an end to it, but I need help. Note: the bottle is empty when he is sleeping with it.
