C.O.
I started cutting back on the bottle around my son's first birthday. I would give him a sippy cup at every meal around 9-10 months and let him play with it, even though feedings still came from a bottle. Eventually he started to drink from it and then we just moved off of the bottle. I held onto that morning bottle until he was 15-16 months or so and then started giving him a sippy cup for that. It took a couple days for that feeding to go welland then we were done!
Good Luck!
