I am exclusively breastfeeding my 5 week old daughter, and she is gaining weight more slowly than the pediatrician would like. She is gaining about half an ounce a day on average, and the pediatrician would like to see an ounce of gain. The dr wants to see her eating 24-30 oz per day. I easily produce that much milk each day (I have been pumping and weighing my baby before and after breastfeeding to measure my output and her intake), but my baby only wants to eat 18-20 oz per day. She is now 7 lbs 6 oz (she was born 6 lbs 10 oz and was 6 lbs 1 oz when she left the hospital 4 days later; I suspect her birth weight was artificially inflated by all the IV fluids I had in labor). She is otherwise very healthy and seems happy and doing great. She seems to know when she's done and doesn't want any more milk. Since the dr said we need her to eat more volume, we've been trying to force her to eat more by pushing bottles of pumped milk after feedings and trying to make her eat every 2 hours. Since we've been doing that, she just spits up a lot more. I've tried nursing her upright and holding her upright after feedings to reduce reflux, but it seems like the more we push her to eat, the more she spits up. Any advice? Is it important to push her intake, or is the 18-20 oz she likes per day OK for an infant of her size and age? I already have a freezer full of pumped milk because the amount I produce in a day exceeds her daily demands. She always has tons of wet and poopy diapers btw, so she is digesting everything and seems well hydrated.
