How often does your LO breastfeed/eat?

My LO is 6 days old and eats non-stop it feels like. He usually eats about 15 mins on one boob and then is still hungry so well do another 15 mins or a 60 ml bottle of formula. But today hes been wanting to eat every 30 mins so he'll latch for 5-10 mins, stop, and then cry to eat again 20 mins later. I know there's cluster feeding but this just seems like a lot
