Hi! I am new here and i started this site in hopes that i can get some help, I have an 8 month old baby boy who is showing no attmepts to crawling, I put him on his belly and he crys i put him anywhere and he cry's, I always have to be holding him. My thing is how far behind is he? My 9 yr old was crawling by 8 months, Is something wrong with him?
