Shared attention!
It is very therapeutical to pay attention to whatever the child does. Just looking at the object he is playing with, gives him the feel of togetherness, which is the first step towards sociability. If you add enthousiasm as well, then you are very effective in helping your child getting out of his autistic isolation!
As long as we try to change the child and his behaviours, we will make him angry, anxious and he will r3eceive the feeling from us that we edon't appreciate him. That is not what you want to give your child!!
When there is another person near him, who is interested in whatever he does, that is very very beneficial!!
