How much milk is your little one eating?

My son was born Tuesday morning and we're all obsessed with him! I'm just curious because little man can EAT. He's 3 days old and is devouring 60ml (2oz) bottles of formula every 2 hours. Is this normal? I went back to my baby tracking app that we used for my daughter and at 3 days old she was just about getting 20-30ml in her every 3 hours. Last night he had 5 bottles between 10pm and 5am. I'm just worried if it's possible to over feed? We're completely taking his lead at this point but the worrier in me is panicking!
