9 month old and not walking or crawling

Hey mamas

I am beginning to get a little worried

My baby boy is 9 month old now

He is unable to crawl, he doesn’t pull himself up,

If I put him in a standing position he will hold on for a few minutes at best.

He doesn’t army crawl

When I put food in front of him, he still only just squeeze it, and doesn’t know how to put it in his mouth.

I want to know is anyone else in the same boat?

And for all the other mamas with babies who crawled and walking already, did you do anything in particular? Like exercises with them? Practice walking etc?

We do play a lot and he’s on his tummy most of the time; he will just try and get frustrated and cries 😓
