My pediatrician is concerned that he's burning too many calories in attempt to eat. She's referred us to another pediatrician who is also a LC. In the meantime, she wants me to pump and bottle feed, and offer the breast if I want, after he's the bottle. My problem is I only have a hand pump right now. I can get a couple good bottles, but then it drops to about an ounce, give or take. I don't think I could possibly pump enough to satisfy him. Suggestions on what to do? Will an electric pump do better? My other concern is that he will start to prefer the bottle. He can drain 3oz from a bottle in no time at all, while nursing usually lasts 45minutes, and he's hungry again in an hour. I don't want to stop nursing, but he obviously isn't thriving by breast alone. Help!
