Over-feeding worry...

lakara
So i just had my little peanut on the 24th at 1:30am. Hes been a great eater and pooper and all that. But as of yesterday since 10am i feel like hes been eating way more enfamil than he should. They told me to feed him 60ml every 3 hours. He seems to want it every 2 and sometimes wants a smidge more of another (roughly 10ml). Im just worried hes wanting way too much too often and i dont know what to do?! He doesnt really vomit anything up. He does have a bit of spit up but thats normal. What should i do?
