Question by lysistrata411:
Autism: do babies display symptoms at an early age or later?

Just wondering if it is possible to notice symptoms of autism when your child is a few months old or when it can be diagnosed. What are the signs? I have seem a bit about it on the news recently and it has me interested. Thanks.
My son doesn’t seem to have any symptoms, but I have heard they can develop later. When does that happen if it does? What should I look for?
