Hungry little 2 month old..

My 2 month old is in this "cluster" feeding stage. He wants to eat more often and feels like more. I give him 3 oz every 2 hours but recently it's become every hour to hour and a half. He cries after each feeding because he wants more :( how much are your babies eating ? I want to feed him more so he won't be so cranky but I'm worried to over feed. Can anyone relate ?
