Sleep troubles with 10 week old!

My baby was doing soooo good sleeping. Pretty much since 2 weeks old he would sleep from 9/10-3 and then 4-7. Well this week I get him to sleep as usual, he’s passed OUT in his crib, and then 30 mins to an hour later he’s up. So I rock him again, put him down, and then 10 mins later he’s up. And this continues all. Night. Long. He won’t stay asleep in his crib! He’ll go down dead asleep and the start wiggling around and wakes himself up so then he cries. But if I’m holding him he’ll sleep forever. 🙄 I’ve resorted to sleeping in the recliner with him after back and forth from the rocker to crib for hours. Do I keep being persistent all night and just keep putting him back down in the crib? He still only gets hungry around 2-3am. Nothing has changed in his routine. Doesn’t have bad gas or anything. Just wants to be held. But I’m on night 5 and struggling bad. 😭
