everything from food items to toys to eating utensils.
Each photo has a piece of velcro behind it and
this helps it to stick to the communication board (bottom left).
Matt seems to be getting the hang of the whole exchange thing. However he does need to be reminded to pick up the picture rather than just reach for the item. And he struggles a bit to get picture off the velcro as it is stuck to the communication board. But once he has it in his hand he is happy to pass it to the communication partner.
