Too much or nah ?

My son was 8 pounds at birth & at his one month well baby check he was 10 pounds. He has been getting bottles of 4 ounces of formula. Still seeming unsatisfied tho after pretty much every feed & although I have been told he should go 4-5 hours before another feeding, he is pretty much ready to eat again after 3 hours or less. I think some say he is just cluster feeding but it’s been like this pretty much since day one. So idk.

He will be 7 weeks old in a few days so should I up his intake to 5 ounces? I’m a new mother & I don’t want to over feed him. I fear making him sick but I want my LO fed & in great spirits.
