Many babies won't take a bottle if mother is in the house, so you may have to leave the house totally. Offer the bottle before baby is overly hungry - try to catch him when you know it's getting close to feeding time. Withholding nursing probably isn't going to make anyone happier - it will just stress you all out in your last few weeks before you have to go back to work. You should be enjoying this time!
