7 month old moving around on her back

[ewiex]

My 7 month old has started moving around on her back by pushing herself along with her legs.
Has anyone else's baby done this? Will this prevent her from learning how to crawl? I've had a look online but can't see anything that is similar.
I'm not the biggest fan of it as it does mean she is rubbing the back of her head on the floor and it does get a little red but she does enjoy doing it! I don't know if I should allow her to continue with it or get her to be on her tummy more to try and encourage crawling.

DD did this and crawled and walked fine. I was impressed with her ingenuity, though she couldn't manage a straight line so scooted along in a curve.

Yes my DS used to do this and would cry when he’d shuffled all the way to the sofa and couldn’t go any further!

He crawled and walked very early.

Don’t worry, she’s just trying out all the different things she can do.

Thank you both, it's nice to have the reassurance as a FTM.

She will be fine! Maybe try lots of tummy time too?

Like body popping? My DS did this, it was quite funny (but he didn't get stuck).
He was slow to walk but I think that had more to do with his enormous legs being too heavy to carry.
