Always remember that every child with autism is different, so don't worry about the things on general lists that don't apply to her, just deal with whichever presentations she has and know they will probably change over time. Some things that are a huge issue now won't cause her distress in another 5 years. Other things may also come and go, just take them in your stride.
Read as much as you can, not just about ASD but all its co-morbids so you're aware of the different presentations of different conditions.

Stop this in its tracks, children with AN often present as emotionally about two thirds of their chronological age.
