How do I fix day/night confusion

My little guy sleeps good during the day 2-4hrs waking to eat be changed and then goes back to sleep fairly quickly. From 3am-5:30/6am he cluster feeds and is super fussy when I lay him down. Finally around 5:30 he sleeps for 2hrs

How do I adjust it?

Edit: not trying to get him to sleep through the night I know he’s too young for that I’m just looking for more then 30-60mins of sleep

Also no he’s not sleeping through til 3am he usually does 10-1 then 1-3. Then it takes about 30-45mins to get him back to sleep then he’s up again within less then an hr sometimes but also just very fussy like he’s restless during that little break
