Verbena17, that's great news that your Ds's care should continue post 18.
As far as I know our local adult ED team still don't treat ARFID. Although I've not checked for a while.
The psychologist at the Maudsley tried her very best to get some continued support local to us, but she came up against a brick wall. CAMHS were not interested and kept saying there was nothing.
I attended a talk recently at a group we go to for parents whose children have ASD. The speaker told the group that ARFID is not an eating disorder and it's autistic fussy eating.
There is still so much misinformation out there still about ARFID. Calling it fussy eating or people claiming to have ARFID, if they dislike just a couple of food items.
It really can be serious eating disorder that can cause a multitude of issues. When Ds started at his specialist college, a member of staff said to him "so you're one of those fussy eaters". It's so misunderstood.
We plod on, Ds is not as ill as he was, but we are far from in a good place. Getting Ds support for any of his difficulties including his eating disorders has been a huge fight, that still continues.
