My daughter is drinking 3 oz every 3 hours. she is 3 weeks old . is it too much ? she weights 7.13. she was 6.7 2 weeks ago ( app she gained too much)

Yes... Maybe...: She is getting +\- 135 calories per kilo. The usual for normal weight gain in a baby should be 80-90cal per kg. The most important determinant if she is eating too much is her growth/weight chart. Your doctor will tell u best. Remember crying is not always from hunger. Try a pacifier or holding.

OVERFEEDING?: She is not gaining a lot of weight. They gain 2 lbs. Every month x 3 months, then 1lb, every month. She now belongs to the 50th percentile.
