my baby is now 9 months old but she is still not crawling.. what to do

A. It can happen by the time of nine months or 10 months right now there is no problem but still since a parent you must be too concerned about it I would say the teacher child how to crawl you also take a crawling position this way you can teach a child that you should be like this and then just for all I’m sure that is going to be helpful
