hi, just wanted to get some advice for my sister in law. Her baby girl is 3 days old, was 6lbs 3 at birth so pretty tiny..Sister in law was v keen to bf before the birth, and still is, however since the first day has been v concerned that the baby isnt feeding well, although have tried to reassure her as much as possible that they just need to suck little and often in the first couple of days. (My DS is 3 months, so i've just been through it all!) They have been giving formula feeds each day, and I just wanted to know whether this is likely to affect her milk supply? As far as i understand it, the baby won't be so keen to feed if already full from formula feed or will it not make a difference. She is already getting sore nipples so i think that is putting her off a bit as well, but i would hate for her to go down the wrong track now and have to give up bfing because of supply problems/nipple confusion etc.
