My son has autism. He was diagnosed when the statistics were 1 in 100,000. Now it's 1 in 88 kids???? I think the spectrum has been diluted by over diagnosing. Now every quirk is being examined. When I see parents saying their child was "cured" of autism I know that the child never had autism. There is no cure.
I never had time to worry about my son having autism because i was too busy dealing with my sons special needs. I still am, and he is 19 years old. It seems a terrible shame that you are missing out on the joys of parenthood because you are worrying about this. My son didn't speak any understandable words until he was five. Was not, and still isn't affectionate. Does not, and never did, play with other children. Never initiated any sort of play with others. He lined up all the silverware on the window sill. Removed all shoes from the closets and lined them up in the hallway. Sensory issues? He would scream if a smoke alarm went off in the neighborhood...his hearing is that sensitive. Has an aversion to light. Cannot stand the feel of clothing. Too many words overwhelm him. The list of characteristics is endless. He needs round the clock care.
I have one child. I would give my left arm to experience any of the "normal" joys and milestones that a parent experiences. Why would you waste even one of those precious moments to worry because he isn't pointing at things? That is beyond sad. I hope you will try to reel in your worries and spend more time enjoying what you have.
