Vent Away

So I cant stop thinking about the "what if's" and they happen to be driving me batty.
What if Connor's peditrician had noticed the ridge in his forehead sooner? I noticed it pretty much at birth (they think his sutures were already closed then) but I didnt think anything of it because I didnt know it was something to be concerned about. Would Connor's brain NOT be underdeveloped if we had noticed sooner?
What if we had gotten Con into the Regional Center at an earlier age? Would he be making even more progress?
What if I had done something differently? Maybe I was too old to have a child? Did I cause this chromosome to be missing?
I cant find any support groups out there to help ease my mind and everyone around me seems to think he is just fine. I KNOW he is fine but at the same time, he needs lots of help and work just to do what other 17 and 18 month old children do on there own and even then, he cant really do them.
He was saying a few words a few months ago and those seem to be foreign to him now. He does pick up words here and there but, will they leave his vocabulary?
What does it mean when they say his brain is underdeveloped? I assume there is no damage so then-FIX IT! Develope that brain.
What if Connor gets teased? What will I do? I cant tell that child to stop. I cant talk to his/her parents but that is about it. All I can do is tell my child that he is absolutly the way he should be.
What if I didnt worry so much?
