6 week old baby's feeding?

A
Hello ladies! I was just wondering what kind of routine do you all have with you're newborns. Mine is 6 wks today and I still don't really got one! I go back to work next week! He drinks 3-4oz every 2-4 hrs. Last night he was going to the 5oz 😳 is it normal? He weighed st 4wks 9lbs 10oz. He's had colics, gases and maybe it's not even that and we think it's acid reflux since he cries every time he is fed. Does anybody relate?
