Wooden flooring - crawling

We have just moved into a new place and the flooring is wooden. My 9 month old is crawling but we were quite lucky where she stuck to the rug we have which now she wants to explore more. I love the wooden flooring we had it all sanded and varnishes so be a shame to ge thick carpet.

What have u done in this situation?

She is crawling fine im just worried about head banging and teeth hitting on floor

We have a big rug but there the living area is quite big so plenty of crawling space which worries me
