Help! My 6 week old is constantly hungry!

My 6 week old is literally hungry every half hour to hour during the day. I’m not sure what to do. He nurses, is calm for about an hour then acts hungry so I give him formula where he will eat 2-4 oz. usually. I’m extremely worried that he’s over eating I try to pace his bottle feeding so his brain has time to process it. I make sure he burps, sometimes he will spit up a little and other times a lot. I’ll try to give him his pacifier and sometimes that helps for a bit. I’m not sure what else to do. Can anyone help me please.
