Too much milk?

My son is almost 4 weeks and he drinks 4/5oz each feed and sometimes 6? He will cry and show hunger cues if I don’t feed him more and won’t settle. There’s usually just about 3 hours between each feed. Sometimes it’s an hour or and hour and a half and he will want at least 4oz if not more. Other people’s babies who eat such large amounts sleep longer at night but mind definitely doesn’t. He will wake up multiple times. Is this too much? He is formula fed.
