4 month sleep regression for the birds 🐦

I would say I have been blessed because.. since my Baby was 4 weeks old he has slept through the night from 10:40-6:15.. the past two days all he wants to do is wake up every morning at 2:30. Then won’t go to sleep unless you are holding him! He was sleeping in his crib but then he was fighting the swaddle so we had him unswaddle in the bassinet. Poor dude only wants to lay on his side!!! So then he rolls into side of bassinet and cries!! Should I test him in the crib? Just worried about him hitting his head
