I took my son off his bottle at 12 months...wow...was I premature ? He got a sippy cup in place of a bottle 1 day and I tossed all his bottles the next day. I was told that the earlier you take the bottle/pacifier away, the better the transition would go, and I must say that it was so easy...and remember, once you've made the change, the more you give in and let them have the bottle back when they won't stop asking for it, the longer/harder it will be. My advice, chuck the bottles altogether so that you cannot go back on the new rule of NO BOTTLE, substitute a sippy cup at bedtime for a few days, then give the night sippy cup right before bed but not in bed, and you'll be done with the whole thing in no time. DON'T GIVE IN !!!
