My son (2.5yo, suspected ASD) has just started speech therapy with a lovely woman. She is using the PECS system which I can see is a great tool for communication.... but my sons problem isn't communication, it's speech iyswim. If he wants something he makes it known by taking me to it and putting my hand on it or more recently (with a lot of work, pointing to it).
I just can't see at the moment how PECS will translate to speech.... would love to hear any PECS success stories or alternative therapies. We are abroad and paying privately so don't want to pour money into the wrong approach...
