Anyone used Merlin's Magic Sleep Suit? Someone recommended that it might help prevent baby from rolling and waking himself up. 

**he can roll from back to belly but not the other way around, when he rolls in bed, he pretty much shoves his face on the mattress and stays stuck there. He doesn't do this during daytime. Just when he is sleeping ** 

I am trying to find the safest way there is to help him through this phase. Any input would be absolutely appreciated.
