I was told off at the weekend by the lifeguard at our local pool, who said I couldn't let my children be naked in the changing rooms. They had taken off their swim things in the communal showers, and then there was a short delay before we could get a space in a changing room. I was really surprised. I guess I am quite liberal about these things - is it inappropriate though? They are 5 and 7. I suppose I feel 7 is borderline.
