Just wanted to say that I hear you! We have an almost 2 week old (tomorrow) and he doesn't like sleeping at night and grunts and whinges and cries all night. He has wind but it's impossible to get rid of. Usually by early a.m. I am so tired I just feed and he falls asleep in my arms (I am lying in bed). Earlier on I sit up and try to feed properly, but for the sake of some shut eye I do whatever it takes later on!
With my DD2 she acttually didn't sleep until 9 weeks. We'd go 15 hours a day awake and grunting/sooking. DD1 never slept more than 1.5 hours day/night until she was 8 months, so I've been here before!
Hang in there (see a Doc if you want) and just know I am out there awake with you!! We are trying to space our feeds a bit more (very difficult with hungry growing boy) but I feel if he feeds too often it makes the pain worse. I also had things to do today with the girls and twice he fell asleep after crying for a bit (not long, but normally I would've picked him up and fed) so it's nice to know it's not all pain or hunger, I think he was just tired!
good luck xxo
