I have a 2 week old who isn't gaining as well as the pediatrician hoped. His birth weight was 8lb,8oz and at his 2 week appointment today is only up to 8lb,5oz. (He lost some weight in the hospital - his lowest was 7lb,11oz I believe - but went up to 7lbs,13oz when we left.) He is exclusively breastfed and has lots of wet and dirty diapers. He sleeps a lot and I feed him whenever he wakes, which happens every 1-3 hours. At night, he can go longer. He eats for maybe 10 minutes before falling back asleep. I usually just have him feed off one side, then do the other side on the next feeding. The pediatrician suggested that I pump after he feeds so that I keep my supply up - just in case.
I'm not sure if I should be waking him to feed more often or wake him up for a second feeding off the other side after he falls asleep while nursing. When I do try to feed him off the other side in the same feeding, he eats a little bit more but not that much before falling asleep again. I don't want to diminish my supply but I'm not sure if constantly waking him to eat is what I should be doing either. I'm trying to feed on demand instead of a schedule since that is what seems best but I don't want to jeopardize my supply or a healthy weight gain.
Any input is much appreciated. He is a happy baby and things are going well, I just want to make sure we can continue to breastfeed successfully and that he is getting what he needs. Thanks!
