I was wondering this as I queued up with some parents and children last week. We were queueing up for autographs from the England Cricket team. The wait was about an hour.
Some parents were in the queue merely to reserve the position for their children (age approx 8 - 15) while they did other fun cricket activities nearby (within sight of parents).
Other parents had their children standing right by them for the duration.
I did a bit of both with my ds and his friend (both aged 14). They were in the queue for much of the time, as I needed to wander off, but sometimes I stood in for them while they wandered off. I did not want any autographs so none of the waiting was for my benefit.
So what's the mumsnet etiquette here? There are so many instances where queues are common - theme parks, cinemas, ice cream vans - do you/should you on principle make your children queue in line with you?
