I'm trying to brace myself, need to start this soon. DS1 is 4, mostly non-verbal. I do think he understands basic commands but I'm not too certain how to communicate such a complex message. We use PECS but are at pretty early stages- choosing food items, etc.
I was expecting his pre-school to initiate, but his class-mates are in their first year, I have a feeling his teacher CBA.
Can anyone recommend useful resources? Thx
