All four-- that must be very stressful. My son was not diagnosed until after my daughter was born. He really didn't show symptoms until then. My daughter doesn't have autism but it affected her in the sense of having to defend her older brother when other children made fun of him. So to this day, she has some trust issues with people outside the family.

I hope you're right. I often wonder who my son would have been had he not been afflicted with autism. I can't wait to find out someday in the hereafter when I hope he will be whole and I will finally find out.
