Just sharing the magic. We recently had to stop using swaddles due to the first signs of rolling. Sleeping for Ophelia became a nightmare until I tried this sleep suit (Merlin's Magic SleepSuit) out. It was my last resort. Lol! It semi immobilizes her through "weight"... like a thunder shirt for dogs. It's supposed to feel cozy and womb-like to help her sleep without the swaddle. So, it's safe for rollers. I hope it wasn't luck, but it worked. Really, it's just a thick blanket suit that looks both cute and hilarious. If you're desperate like we were--know there are options out there!
