DS is 4 months old and I've been back at work FT for 2 months. I've been pumping three times a day (~21 oz) and then bf at home. Lately though ds has been showing a strong preference for the bottle. I try to bf and he screams. I want him to eat so I pump and dh gives him the bottle. He will always bf at night for some reason so I get at least 2 sessions in a day. I mentioned this to my pediatrician at the 4 month checkup and he said that ds is punishing me for not being there during the day and that all babies who are fed from the bottle and breast will eventually go 100% to the botltle. This was a really frightening prospect for me, so I asked if he thought I could keep up my supply by pumping more than three times a day and he said no, that soon I'd have to start mixing formula and bm. I've had a little success lately getting ds back to bf using some techniques on this site and others but he still refuses quite a bit. Any thoughts to share? Thanks a lot.
