Baby not crawling yet

My baby girl was born April 14 and isn’t crawling yet. So she is almost 9 months old.

She can army crawl and scoot her body well but not like fully on all fours crawling across the room fast.

She has enough space to crawl and I encourage her, but she doesn’t seem interested. She just likes laying around playing with dolls and babbling looking at picture books haha.

Anyone else’s baby not fully crawling (I’m not talking about army crawling I’m talking about fully on crawling across the room)?
