charges for letters and unnecessary waiting

Summary: charges for letters and unnecessary waiting

My friend has a ** year old child. She started long periods of bleeding early and her body is more grown than other girls her age. She is being bullied. She is anxious in school needing to go the toilet more often as worried about staining her clothes. The school have demanded a doctors note to let her out of lessons for the toilet. The surgery is charging £50 and said the letter will take up to 30 days to be ready. This is so not fair on the child and why do you need to pay for a letter for a child? At the moment she is having to walk out of lessons with the punishment of detentions.
