That makes sense. There's a lot of good coping mechanisms and therapy that can help the kids to learn to manage their autism and grow into happy adults - doing theatre or improv is a good way to learn and practise how people express different feelings, and playing sports or card or board games helps them learn to take turns and interact with people in an easy context with nice clear rules. And resources for other special needs kids can help, and therapy and breathing exercises for managing phobias, panic attacks and anger work pretty well for managing meltdowns. But it's a long process of accepting and managing the condition rather than a cure.I think because it’s something that can’t be cured or even treated medically, it’s something the kid’s never growing out of and the chances are that there will never be a cure. Parents are easily suckered in by false hope.
Basically just take them to real qualified professionals and keep them away from Sonic the Hedgehog and you can't go far wrong.
