How did you transition from a swaddle?


We tried to transition him by going cold turkey and using a sleep sack. He woke up every 30-45 min the two nights we tried it. Last night we tried the magic Merlin sleep suit and he woke up twice from 7:30pm-8:45pm so we just put him back in the swaddle. But when I went into his room to feed him at 4:30 this morning, he’d broken out of the swaddle again. It’s always his left arm. Any tips? Is it normal for them to wake up so often during the transition or is there something else i can try? And if so, how long did it take for them to get used to sleeping without the swaddle?

Edit: I should also add that he’s 3 months old.
