rotating baby

Shelby • Baby girl born may11 wasn't due until june2. Love my princess
My LO constantly lays on the one side of her head whether she's in the car seat,play pen or her bed. I'm just wondering what I can do get  her to lay on the other side willingly, everytime I catch her laying on the one side I make sure to move Her head to the otherside but then she stretches and moves back to how she was
