Right, I run music classes for littlies and am taking a child who's non-verbal, seems to love and respond to music and doesn't sign yet. I think he has limited understanding, a couple of words and I want to help in any way I can. How can I help him, do I use a couple of PECS, how do I start to use them, where do you learn them and should I sign too? He will be in a big class of kids, but his mum sounds lovely and I need your advice please.
