I have a friend who has a gorgeous 13 month old son. He isn't crawling or walking or even making any attempts to do so. The child nurses have put the fear into her saying that he should be at least getting himself about. She asked me if I would be worried if it was DD. I didn't really know what to say as I'm really not sure. In my opinion babies do things at their own pace - which is totally the correct thing to say but didn't make my friend feel any better as the nurses have really worried her.

What do you think? Should she be worried?
