So, fully prepared to be told I'm being unreasonable, that it's disruptive to other students etc, but if your year 9 daughter has her period and is flooding, surely it's BU for teachers to say you can't use the toilet in lesson time unless you have a medical exemption for bladder problems? She had to sit for the entire lesson, refused permission even when she had to describe the problem to the teacher. I mean, really? I knew it was a new policy that the school had introduced, but I think it's ridiculous.
