If you are still breastfeeding, then you could probably start dropping bottle feedings one at a time. For instance instead of giving him a bottle at 9 am, you could offer him cereal, oatmeal, and a fruit. At lunch time, give him food first and then offer milk. Most of the time, they will be full if you provide food before the bottle. At night you could offer milk in a bottle, but after meal time. You want to make sure that he is not using the bottle to go to sleep.
