My DS is 4 months. I breastfeed and he has 2 bottles during the day while I work. HE is on 4-hr easy. His eating is very erratic as far as how much he eats. Sometimes he will take only 2oz. sometimes he will take 6-7oz (but that is very rare). On average he only eats about 3oz during a feeding. But he can go 4 hours between feedings and not be hungry at all. He doens't even cry or get fussy to eat at the end of 4 hours. I just assume it's been 4 hours I should feed him. Yesterday he got up an hour early at 6am so his schedule was an hour off. He ate at 6, 10, and 2. At 2 he had only 2oz. Nighttime I do the same routine and put him to bed between 7-7:30. I bath, feed, book, bed. I fed him at 7p last night and he still wasn't crying to eat or anything, he was very contented for that 5 hours in between feedings. He didn't even have a good feeding at 7p. He ate for 5 minute and not even aggressive sucking. After taht I had to try and keep offering but he would bob off and just smile up at me. I ALWAYS feed in a dark room with no stimulation, otherwise he'll never eat. He is still feeding twice a night and I would love to wean those but since he just WON"T eat more during the day it's impossible to get him more daytime calories. I try clusterfeeding at night and that makes it worse, if I feed him at 5 he just will not eat anyting at 7 before bed. I would DF but he usually wakes up anyways around 10 or 11 and I feed. After that he wakes at 3a or 4a. I find that my milk supply is depleting between his short feedings and pumping at work. I used to pump a good 6oz (3.5 from one and 2.5 from the other), now I only pump 3.5 all together. Is my milk supply depleting because of him or is he eating less because of my milk supply? His daytimes are great, perfect 4 hour easy. he seems happy. I haven't weighed him since the last dr. appt a month ago and at that time he was 13lbs, I am figuring he is about 14lbs now. He was born at 7.2 so he is gaining. I just wish he was a bigger eater. Should I be worried - how do I deal with this?
