Well first, I'm glad he's ok! Second, I'm surprised the ortho didn't give a cads or a brace. The radius is one of the two bones in the forearm, even if it had a small fracture at the wrist it still seems like keeping it immobile would be best. But, that's just my two cents.As far as crawling goes, you'll just have to wait and see. I'm sure you already know this, but plenty of kids never crawl at all. Crawling isn't a very important milestone because there's no standard way that all kids do it, if they do it at all. At this point, there's still a few months before your son will start to walk on his own, so his scooting may turn back into crawling, or it might not. It will mainly depend on how well he feels he's getting around and how much his wrist hurts.Don't be surprised if his wrist causes him some pain throughout his life. Both my mom and my husband broke their wrists at different times in childhood and now as adults they still have pain.
