I’m scared :(

Baby drops her head during time mostly just when she’s tired but also sometimes just for fun, she never hits the ground she just drops her head down for fun.

But just know I was watching her do tummy time and she dropped her head and hit the ground (not hard/thick quilt plus rug) and the. She looked at me and giggled like she thought it was funny fun.

She’s 7 months old and this behavior is freaking me out so much….

Is anyone else experiencing this.

When she’s on a hardwood floor she’s very careful and her behavior is totally different
