I don't want to give up breastfeeding, but I feel like I am starving my LO. My son was born 4 weeks and three days by c-section following a 24 hour induction and arrested labor. He was born at 8lbs 10oz. I began breastfeeding as soon as I could. The first two days were rough with painful latch problems. The three day weigh-in came in a 7lbs 12 oz, which resulted in the doctors and consultants advising supplementation. Day three evening started to reject one of the breasts, and by day four was nipple confusion leading to rejection of the other breast. Milk came in fifth day and, with determination, was able to get LO back on the breast by avoiding other nipple types. We went in for weigh-in at one week (on a Monday). He only weighed 7lb 10.8oz. Doctor wasn't concerned considering that my milk had just came in basically two days prior. Also stated that scales are different from place to place and he was very alert, healthy looking, etc. We went back in four days later (Friday) and he weighed 7lbs 13.8oz. I was happy and thought we were improving. After noting to myself that he is just so skinny, I decided to go back for a weigh-in last week when he was three weeks and five days old (two weeks later). He was only at 8lbs 3.0oz. Only 5.2oz in two weeks? Our doctor was out, but another said everything looked fine. I called our doctor later, who said everything is okay and while she doesn't think it necessary, I could supplement only after nursing so not to reduce my supply. He won't take the formula (grimaces), so I am trying to pump (manual) after feeding/in-between times and can barely get .5oz in ten minutes on both breasts. Our latch is good and I can see and hear him swallowing. I let him finish a breast before the other. He is constantly feeding. He used to dirty his diaper like after each BF, but lately just probably 4-8 dirty diapers and I believe adequate wet diapers. Sleeps well at night (4 hours, then 2.5-3), but napping during the day is sometimes rough as he wants to be at the breast. I am going to see another doctor tomorrow because I am super concerned about him not at birth weight at four weeks old. Is there anyone that has dealt with a slow gainer like this? Sorry so long, just worried and looking for reassurance. I want to keep breastfeeding, but not at the expense of my LO not gaining weight. Thanks.
