Arms out?

Did anyone just cold turkey the arms out situation? Baby is about to be 3 mos but has been sneaking his hands up the snoo sack every night! We swaddle pretty tight but he still figures it out. I don’t know why I’m adverse to the one arm out then both arms out I just feel like going for it lol. Anyone else do it that way? Going to try just naps for now. He only naps 30 mins anyway.
