Baby’s sleep schedule? FTM question!!

My two week + four day old is exclusively breastfeed. During the day, he eats every two hours and sometimes the time between feedings is even less than that. However at night, he cluster feeds until about 12am and then sleeps for 4 hours (until 4am). At 4am he’s up feeding off and on until 6 or 7 and then sleeps for another 4 hour stretch.

Is it ok to let him sleep for four hours at night? He’s half a pound above birth weight but he’s only been in this sleep routine for a couple of nights. Has a pee and a poop every time he eats!
