sleeping on tummy

Va
My four and a half month old decided she is definitely a tummy sleeper recently. She just keeps waking herself up because she can't decided how to make her head comfortable. Lol she's a nut 
I know that when they can roll there on their own it's safe and I still put her down on her back but man back sleeping gets drilled into you so much it still wigs me out  😳😊
