Rollie pollie in her crib paranoia

Alrighty my mommy friends. My 6 month old has learned to roll from tummy to back and back to tummy. However only on the right side. I am very huge on sleep safety (sleeping on her back, nothing in the crib with her, and no bumpers). However she is constantly rolling around all in her crib, little extremities reaching between the rails and not sleeping on her back. I am super paranoid about SIDS or her suffocating herself. She wakes herself up by rolling so much or I do by putting her back on her back. Any advice?
