Too late to feed?

No, it's definitely not too late. I would get in touch with a lactation specialist and she can advise you of different things you can try to re-establish feeding. These would probably include pumping every hour to stimulate milk production as well as herbs and possibly medication to get your milk going. Don't just discontinue bottle feeding right now as you won't have enough milk to satisfy your baby. As your supply increases though, you will be able to stop bottlefeeding. Getting in touch with a good lactation specialist is the first step. The hospital you delivered at can probably refer you to one.
