How much does your little one eat ?

Sonia
My daughter is 7 days old and I think she eats alot but I'm not sure . We breastfeed and pump I pump out 4 to 5 oz and she breast feeds afterwards if she drinks all the milk or I save anything after 4 oz and let her just breast feed . Is this alot for a newborn ? Anyone else's little one have a hearty appetite?
