I've had this problem with two of my kids, here's a few things that might help:
1) What do you do when he won't take a bottle? At first, I would just nurse him after we tried for a while....until I realized that might be why he wouldn't take it, he could just hold out for the boob. Then I started NOT giving him the breast until after we'd tried the bottle for two feedings in a row. Sometimes these would be hours apart. For example...try the bottle first feed in the morning (he may be hungry enough to take it). If he doesn't take it, don't nurse him, instead wait until the next feeding and try the bottle again.
2) Try sneaking the bottle to him while he's still half asleep. Don't wait until he's HUNGRY to feed him, get him up when he's still a little sleepy and see if you can 'sneak' it in.
3) Try lots of bottles, which you have. Mine liked either the Avent, or the Playtex Natural Latch (these were silicone and so soft!)
That's about all I can think of now...good luck!
