Baby pushes head against crib bars

Six m/o

I'm worried about her soft spot?

She'll spin her body until she's laying "the wrong way" (like short side long ways lol) in the crib then push the top of her head against the crib bars.

This doesn't wake her up, but I'm worried about her soft spot?

I tried having her sleep in a packnplay until her movement lessened(since it has mesh sides) but she HATES that.

Any mommas dealt with this? What did you do?

Idk what to do :(
