We had our first meeting with Ed Psych who suggested PECS for DS (aged 3 currently being assessed for ASD). He has high levels of understanding but low levels of output if you see what I mean. He is still at 2 word sentences, mainly requests but we are working on that to try and build on it. The SALT has never mentioned PECS as an option and I am not sure how useful it would be. I admit I dont know that much about it but wouldn't he stop verbalising and rely more on giving me a picture?
