transitioning from swaddle-Merlin magic suit

Marissa
So my little lady is doing perfectly except for not being able to sleep without being swaddled she's starting to figure out how to rollover from back to tummy and now I'm panicking. I've tried not swaddling her arms and one arm and have had no luck won't sleep more then 2 hours without waking up and usually she sleeps 9 hours at night straight thru. 
Has anyone tried the Merlin Magic Sleep Suit or any other products to transition there baby? 
I kno soon we will just have to leave her not swaddles with her rolling over. Right now she can't do it without her arms but it won't be long. Help please?!?
