Yeah, high-functioning ASD.
If I were to give advice, the first three tips would be:
-Trust what your child is telling you, over what common sense is telling you.
-Never hesitate with getting a skilled psychiatrist involved if there are any issues with school, medical issues, eating, etc. Because their standard playbook is usually insufficient and by the time they manage to dial in to your child enough to help, a long time may have passed.
-If someone tries to tell you how to "cure" the child, hit them in the face with a pickaxe.
