Proper feeding amount

Jocelyn

I'm wondering how many ounces a little one should be drinking at 1 month. My baby girl has 3 ounces every 3-3 1/2 hours but many times she stays awake, gets fussy and sucks on her pacifier for quite some time until eventually she falls asleep. I'm thinking she may still be hungry? How much is everyone else's little one drinking at 1 month?
