We are a 2-language family, living out of the UK (not my native language). DD1 experienced a regression in the months after our move and is now on the pathway for an autism diagnosis. She is attending DN daycare and receiving speech therapy etc - currently all in the language of the country we live in.
I know that even for autistic children, keeping up both languages is encouraged and apparently not expected to add to delays. I can't help but think by focusing on one language only, DD is more likely to progress to communicating via language than if we try with 2 (she's currently non verbal apart from echoalia etc). My language is good enough to learn along with her, although much worse than my native English.
Does anyone have any lived experiences / helpful views to share?
