My DS is 3 and has asd. We started doing PECS within the last couple of weeks and he is (luckily) picking it up very, very quickly. We are currently working our way through the stages (I've heard there are six) and about to start stage 4. I was just wondering how long it took other people to fully implement PECS i.e. where the child is using it on a daily basis to ask for everything they need.
Also, once using PECS, did it help you child to eventually communicate verbally? My fear is that DS will become reliant on the cards and never actually feel the need to speak.
