I agree with trying to get him to take a sippy cup instead of the bottle. However, don't let him take it to bed with him, because that is what rots little teeth. Milk is good, no harm to the teeth I actually just read it's good for strengthening enamel, but can cause excess mucus which might make it hard to breath. Especially if he has a cold. Just try it everynight, but don't force it you don't want to upset him, and before you know it he'll be done with the bottle. Keep your same routine, just give the cup instead of the bottle. I used to hold my daughter every night and give her a bottle. When she turned a year I started to give her a cup, but I would hold her and the cup for her. Slowly we transitioned into her holding the cup herself and sitting next to me instead of on me. Her brother was then born a month later and she knew that the bottles were for the baby. She was 14 months when it was totally gone. Also, she did give up the nap bottle first so your on the right track. Good luck!
