My daughter has been invited to go on holiday abroad with her best friend from school. Apart from sleepovers she's never been away from home and never been on holiday with another family. She's 11 years old, and too young in my view. Her friend is lovely but I don't know the family well, it's been a term at her new secondary school and parents don't meet up often. Once she's older and more confident I wouldn't mind. Am I being unreasonable? Your thoughts/advice would be welcome.
