We personally did not have the bottle feeding issue, but our niece did. Basically it took a couple of weekends when my sister-in-law had to leave the house for at least 8 hours and then Daddy and baby just fought it out. Once they hungry enough, they will give in. The best thing you can do is give them time without you. I would suggest that he offer the bottle and if your son refuses, then play. Don't make it a struggle, but by the end of multiple hours, I truly think he will get hungry enough to eat. Good luck!
