DS1 has a history of school refusal, but not in the past 3 years (since he started high school). When he was in Y6 we found the best approach was to let him have that day off, and start afresh the next day.
Today, rather than leaving for school he stood quietly weeping in his bedroom. I could see he was too distressed for school, so told him to take the day off, making it very clear he was going in tomorrow. I went to work, came home at lunch time, and managed to work out he had been so upset because DS2 had ruined something on his minecraft game. DS1 spent the day putting right what was wrong with the game, and is happy once again.
I emailed the school explaining the situation before I knew about the minecraft problem. I thought if he's going to start school refusing again, we need to be working with the school, rather than pretending he is ill.
Do I now admit to the school I know why he was off? Part of me is appalled and embarrassed my child missed a day of school because of a computer game. But a friend who is a SN TA assures me I did the right thing.
