My LO was born full term but weighed only 5 pounds 4 ounces, and was 19 inches long. At her 2 month appointment 2 weeks ago she was up to 8 pounds 13.5 ounces and 21 inches long. At that time she was eating around 16-20 ounces/day. The doctor wasn't concerned, and said she should take 21-24 ounces.
She continues to eat about 17-20 ounces per day, which doesn't seem like enough to me . . .but she seems happy and feels like she is gaining (just not sure if it is enough!). I have tried feeding her more frequent, small feedings as well as larger feedings spread out--either way, she still won't take any more than 20 in a 24-hour period. Any other suggestions? Am I overanalyzing this? I just think it is odd that she is on the small side since my husband and I are of average size . . .
