How much is too much at 9weeks old?

Cindy💙💙

Hey ladies my beautifull baby boy is 9weeks old, he ranges from about 3-4ouncea, to be honest I just started giving him the 4th ounce. He seemed way to hungry after a feeding on 3 but every other bottle he will only want 3ounces, soooo I'm thinking is 4ounces to much for his age ladies?
