Hello Shubh.

Being the parent of a son with autism and and typically developing daughter, I share in your concern. I have done some reading about this topic, and found the following quote at www.childrensdisabilities.info/autism/interview-harris. I think it is good advice! I know it is not easy, but I wish you luck!

Sandra Harris: The best way to encourage interaction is to make sure both children have the skills to play together. I think it is a good idea from early childhood to find simple things your children can enjoy together. The child with autism should be taught some games he can play with his siblings. It may start with rolling a ball or playing catch and gradually become more elaborate as they grow older. Older children might jog or shoot baskets. If they have a tradition of spending even a small amount of time together the time can gradually be expanded. Older siblings in particular may enjoy learning some basic teaching skills so they can be "teachers" of play. David Celiberti and I did some research in which we taught older children to teach basic play to younger brothers with autism. The videotapes we made showed how much both children came to enjoy these play times. Beth Glasberg and I discuss that kind of interaction in the latest edition of the sibling book.
