Is my newborn eating enough?!

frankie

my baby was born when I was 37+4 days, she weighed 5 pounds 11 ounces. she is now 6 days old, she eats only 1 ounce every 2 hours.. i try to get her to eat at least the whole 2 ounces but sometimes she won't. yesterday she went all day with only 1 ounce per feeding . I feel like that's not enough. but she seems to be doing okay with that amount (enough poopy and pee diapers) im just a little worried that thats not enough
