My daughter is turning 15 (y10) and wants a houseparty - we'll hide upstairs, but now we are questioning whether or not alcohol should be allowed - its invitees only and my 17 year old son will act as bouncer - her friends are generally responsible so we were thinking cider/WKD's/punch ? not a lot and confiscate vodka or anything stronger. Also finishing times? She's begging for 1am or something similar but we think unwise to end after midnight, let me know your thoughts.
