As of Sunday I'm home with a 17 day old preemie (born at 34 wks) who is favoring the bottle over breast for obvious reasons. Nurses told me I have flat nipples. I've tried pumping before to get them to stand up and my boy still shows no interest. Nipple shield frustrates us both though it does work from time to time. Hosp sent me home with Neosure 2xs a night for continued weight gain (anyone know of a 22 cal organic brand btw?). I've all but abandoned the breast for now; am I making a mistake waiting until he's older to reintroduce breast? Should I keep trying even though he isn't interested?
