Thanks, kcab, and I hope your son's anxiety eases. DS came home today saying that his teacher had had a new idea: she's given all the children two laminated cards, one saying "I'm OK" and the other saying "Help" so that if they need help but daren't ask out loud they can just display the Help card! This in reaction to DS having *three* such occasions yesterday when he just sat and did nothing because he wasn't sure what to do next. Seems like a good idea, and I'm very happy to hear that his teacher isn't out of ideas yet!
