How much should each feed be?

Katrina

My daughter is 10 days old today, and I've been in the hospital with a bad kidney infection for the last 3 days. I've been pumping while I'm here so my husband can feed her. When I left she was only drinking 1.5-2oz of breast milk. We were also doing occasional direct breast feeding. Since I've been gone my husband says she's been eating 5 oz!

Am I crazy to think that's a lot? I mean if she really needs that much that's fine but I'll have to start supplementing since I only pump around 4 ounces each time I pump..
