There are many trainings out there who are catered for Autism children. Don't need to worry much, just cooperate with the specialists and try to understand the children's inner self. Show her your love, she will understand. Generally, Autism children are more sensitive than the others. So try not to say something to hurt her feelings. Stay positive. You have done a great job already as many parents, basically don't even 'notice' their kids have Autism and that's why many of those were being delayed and missed the golden time to cure the disease. Autism is getting very common nowadays and some kids with mild symptoms, may easily be missed.
