Baby can’t get comfy

My daughters almost 6mo and she usually sleeps on her tummy.

The past few nights it’s been so hard to get her to stay asleep or fall asleep because it’s like she can’t get comfy. Not on her back tummy or on either side. I tried to lay he with her head turned to the left or the right. Nothing.

And when I watch her move around tryna get comfy it’s like she wants her head straight down in the crib or with her hands under her face.
