DS1 was complaining the other day that I always choose the films - because I refuse to pay £xx to watch complete and utter rubbish. So I asked him to ask what the cinema guidelines are for children on their own.
Apparently unaccompanied children are OK before 7 pm at any age 
Later than that they have to be at least 12.
(Obviously they can't see a 12A without an adult with them.)
We went to see a film and the only other people in the cinema were two young boys, aged about 7 or 8: They were really good. They sat at the back and were so quiet we didn't even know they were there until the end!
So what age would you/do you allow your kids to go to the cinema without you?
