Hello, I am new to this forum and would like to ask advise from adults who are diagnosed  with asd. Do you think it is better if children understand their diagnosis early, we are in the process of getting my 11 year old daughter diagnosed. I am getting some critisim saying I am labelling my child and this will be negative for her. My gut instinct is that she is a clever individual and that if she has the right support from us she will better understand why she feels the way she does. Would you have preferred to know or would you have prefered not to know as a child? Thank you for your help :)
