How much does your 2week old drink or drank at this age?FORMULA FED 💙💙💙💙

Ladies my baby is 2weeks and 2days old, he eats usually every 3hrs 3ounces, sometimes he will cluster feed through the middle of the night, I'm not sure if 3ounces is enough for him though, sometimes an hour later he is hungry again. Is this safe to feed him more so soon an hour later? He's tiny but I just feel maybe 3ounces some feeds aren't enough, now there are times he won't even take 2ounces so every feed is different. I don't wanna over feed and cause him gas or fussy press but is it okay for a 2weeks old to have alil more if he wants it?
