Thats true. But, what also is true is that the "experts" put things in parents heads, too. "With this technology, this surgery, this brace, this whatever, your child will walk." So, the parent does whatever is suggested, and it often just screws the kid up.
I can still remember very clearly the day that I came home from school, threw my crutches down and told my Mother I was NOT going to walk anymore with them, and that was that! She wasn't quite ready to appease me, however, and it was another two years before I finally was listened to, and it was "OK" that I didn't use the braces and crutches anymore.
As for me, I knew I was different and I was OK with it. As I grew into a teenager, I became angry and had this atitude that I didn't care what others thought of me, and I didn't. I became a loner and talked myself into the idea that I didn't need anybody. I had sort of a false confidence. It became my protection against all the crap I had been put through. It was years before I actually learned to trust people.
