Most years we (as a family) go to a friends house for NYE. Lots of families go, all with kids of varying ages who have known each other all their lives. It's a great set up and works well. However this year DS14 has now said that he wants to go to a house party with friends from school. Parents will be in upstairs and kids can all sleep over. Trouble is if DS goes to this house party this will leave one other 14 year old (son's friend, but not as close) the only teenager at our party with a load of 8-11 year olds. I've said that it is too late in the day to change plans, but understandably DS is desperate to go to house party with all his friends rather than one with a load of family friends. Should we let him go?
