I came upon this older, but relevant and great article from Time’s online site–>http://www.time.com/time/health/article/0,8599,1698128,00.html

I have 3 autistic kids, 10, 15, and 15. They argue, they fight, but I think that they love one another and care for each other as well.

And they have to be, given the myriad challenges they face: parental responsibility; a feeling of isolation from the rest of their family; confusion, fear, anger and embarrassment about their autistic sibling. And on top of all of it, guilt for having these feelings. (See six tips for traveling with an autistic child.)
