I’m a big fan of AuKids magazine that comes out of the UK.
It’s one of the richest and most accessible resources I’ve found. They address important issues in highly readable ways. The co-editor, Debby Elley, is the parent of twins with autism who provides perspective and good humour to the journey.
Disclaimer: yes, I do contribute to AuKids from time to time purely on a voluntary basis. I think it’s that good.
