I hate to say but my DD1 had a bottle until she was FIVE!! Yes 5!! AND.. .she is ok! She never ever had it in bed, she had one upon waking (thank the lord for a few mins peace) and then one before bed. She ate properly in between, has never had teeth probs (only other thing she drank/drinks is water) and I knew she was getting her calcium.
DD2 on the other hand, gave up bottles at one year of age (she'd only had them a couple of months). So I go with the flow here!! xo
