How much is/did your 3 week old eat...

Per feeding?? My little girl is working my nerves taking an ounce and a half and falling asleep and being hungry again an hour later.. lol. Or she goes 4 hours ((never at night.. always during the day.. yay for the no sleep club)) and then wants 4 ounces. She was 6lbs 10oz at birth, 8.8 now. I can’t remember how much my son ate at any point.. and his bottles had to have cereal in them at this point to keep anything down ((horrendous acid reflux)) so I can’t really even draw a comparison. She’s a hungry hungry hippo....
