Baby only sleeps swaddled?!

Ni

If you had a baby that would only sleep swaddled, how did you make the transition once they were too big for it? My baby has almost outgrown his swaddles and he won't sleep for more than 30 minutes at a time without being swaddled. I'm so not looking forward to when he either completely outgrows his swaddle or starts rolling over and I have to quit cold turkey.
