I have a son on the spectrum and this was a part of every day life. When he was diagnosed, we basically did activities that provoked him and pushed him to the edge and then brought him back again. He learned tolerance for things that did not go his way and coping strategies for his frustration. I would not say that he is cured, but he is a different child. There are difficult days, but for the most he can manage most things very well. So, the key is how to get your daughter there. Well, you really need the help of a professional. You may want to start with your pediatrician or school system (even if she is not yet enrolled) to get some recommendations. I had a whole team of special ed. consultants, neurologist, speech, OT, and behavioral therapists and they all did frustration management skills, but I think you will likely need the help of a behavioral therapist. Your school system may offer assistance as this will affect your child's transition to or participation in the school.
Good luck,
C.
