Anyone’s baby crawling?

We have been practicing with our girl to sit up on her own and she will be there soon I think, but the last couple days she has been on her hands and knees rocking back and forth!

Our older daughter sat up with no support right around 6mo but then didn’t crawl till 7.5mo! But then all in one month she crawled, pulled to standing, stood alone and began taking steps with a walker all within that 7mo age range.

Anyone’s babies crawled before sitting up??
