Rolling from back to tummy

Carly

My sweet girl is 5 months old and has been rolling from back to belly since she was 4 months. Out of no where, she’s been rolling onto her tummy during the night and during naps. She can’t roll back onto her back on her own she she just cries. But she keeps waking herself up because she’s constantly rolling onto her belly. Is this just a phase? Is there something I can do to help?
