I agree with those above who say that it is a little early to get your baby evaluated. Very normal to begin to crawl at 10 months. And some babies never crawl, but just scoot around on their bottom, leaning on one hand – kind of propel themselves along while in a sitting/leaning position. (Hard to describe, but anyone who has seen it knows what I mean!)
Also, now that pple are putting their babies to sleep on their backs, rather than on their tummies, crawling later or not crawling at all, is much more common. This was the case with my own daughter, who is now perfectly fine B”H. I would just make sure she gets plenty of floor-time and plenty of tummy-time too. The therapist who evaluated my daughter advised that every time I change her diaper, give her tummy-time. I would put her on her tummy and put toys around her out of reach to give her incentive to move.
Hope that helps!
