You may have missed the part where I explained that she is 9 years old now and perfectly fine.
And you may have missed that my post refers to that same now-protected child when she starts going out into the world, especially the world of work, which will be some years from now. That is why her coping skills need to be developed now, not after she experiences intense frustration and rage when she gets out there and discovers how disorderly and challenging society can be for the differently abled. I speak from family experience here. Our family denied the impact of ASD on two individuals, who then struggled greatly as adults after leaving the protection of home and parents who had understandably catered to their uniqueness in a way the world outside cannot be expected to.
