My daughter is 16 years old. She has asked to go to reading festival for the entire weekend. We were initially unsure but did agree we would think about it but in the meantime she would need to revise and work hard at her AS level exams in May. We said we would review the situation then. She has now gone ahead and booked her ticket (albeit with her own money from her Saturday job). We are really disappointed that she has just gone ahead anyway regardless of how we feel about the situation. Please can I have some advice with how to move forward.
