My DD (aged 7) told me that because she had to go to the toilet during a lesson she lost 5 mins of Golden Time and had to stand facing the wall in the book corner. My older DD said that the rule is you lose 5 mins of Golden Time (which I can understand as there are plenty of children who no doubt love getting out of lessons).
I think facing the wall makes it a form of punishment and feel I should write to the Head. What do they do in other schools?
