Hello! I'm a 33 year old mother with two Aspie children, the youngest of the two just being diagnosed. I have a couple questions that I would love to hear from others on. First, have researchers found that autism or more specifically aspergers been linked to being hereditary? I ask this questing because I now have two Aspie children and a possible third, which leads into my second question. I have a son who will be two years old soon, that isn't talking, he seems to hear fine but is scheduled for a hearing test. None of my other three children have ever had a delay in speech. Macen, (my two year old), has always developed quickly and exceptionally in all his milestones but speaking. He does communicate, he will follow all directions so his comprehension is there, he also points and gives other cues when in need of something. I'm concerned Macen might also be autistic? I say concerned because my husband is having a hard time with this. Can anyone help with theses 3 questions? What are early signs of autism in babies and is delay in speech one of them? Is it carried by patents, genetic?
