Baby eating little

[mltina]

Please Please help!!! I think I am going crazy...My 2 1/2 month old daughter is hardly eating now. She was born 8lb 3 ounces. She was always breastfeeding 5-10 min at a time every 3hr and was putting on weight 1/2-1 ounce a day. I was happy with that even though I was questioning the time spent on the breast. She began fussing at the breast when she was about one month old. She kept pulling off and crying and I thought she did not like the breast/let down. I started pumping and she was taking 60-70ml per feeding, every 3hr. For the past month, she will only eat 50ml or less per feeding, with a big struggle/crying. The only time I can put some food in her is when she is half asleep....She does not really tell me when she is hungry so I have to try feeding her every 1.5-2hr. Then the crying/food rejection starts. Otherwise, she looks happy but can't stand the fact she needs to eat. She can go on without food for hours. She sleeps through the night and when she wakes up in the morning she does not seem interested in the bottle/breast. Once in awhile, she will wake up at night to feed and will only do so for 5min and go back to sleep. I've talked to doctors and they don't seem concered as she is not losing weight, but gaining the minimum......they call this "fussy eating". If I did not feed her when half asleep she would definitely start losing weight.
