Is your baby crawling ??

Kesh
My daughter is 7 months she will be 8 months on the 16th she is not crawling .. is that kinda normal?? She sits up and acts like she wants to crawl but then cries or grabs somthing to chew (teething) lol tummy time is 50/50 .. I stay at home so I just don't want her to be behind .  😔
