One reader asks:
I sometimes look after a friend's three year old. I have worked with a few autistic children that were age 3 or older when I was preschool teacher's aid. I see some similarities in him that I saw in a couple of them. I believe that if he doesn't have early signs of PDD that he has some significant delays at least. Do you have any advice? Mom would be hard to talk to, but I know early intervention is important.What's your take on this? Is it appropriate to say something to a parent of a child who may be at risk of autism? If so -- what should you say, and how should you say it?
