L.B.
If you have a pump, start giving him a bottle in the morning of 1/2 breast milk & 1/2 milk and do that for a week, and then start to replace the next feeding with the same until you gradually get him to take a full bottle of milk and a few extra feedings of the bottle throughout the day. Don't be in a rush to replace the feedings in the middle of the night with a bottle or he may get up even more to eat! When you get him on a bottle just before bed-time (8pm), add a tablespoon of rice cereal and see if he doesn't sleep through the night for you. You can gradually get him on the sippy cup the same way.
