Anyone else's 1 month old eating all over the place

He did the 2-3oz every 2-3 hours thing for 2 weeks, them the last 2 weeks has been like an oz 4oz 2oz 1.5 oz 3 oz 4 oz doesn't matter how long he sleeps . For instance ate 1oz slept 3 hours , ate 4oz slept 3 hours ate 3oz slept 1 hour ate 2 oz slept 2 hours ate .5oz and he's been passed back out for almost an hour again.

There's no consistency or pattern at all . Like sleeps less eats less / sleeps more eats more . It's completely random!
