How much is your 4 week old eating?

How much is everyone's 4 week old baby taking? My little boy usually eats between 5-8 oz a feeding...We do all we can to make sure he's actually hungry,like try the pacifier instead,etc. How much is yours eating? My son at his last apt was almost 10 lb. he was 8 lb 1 oz at birth,and 20 in long.
