I read and appreciate the comments on my invitation wording question. Keen pointed out that there is no gracious way to state that children are not allowed. After I thought about it, I came up with a possible solution.
What if I state that the party is 21 and up because alcohol will be served??? Everyone normally invited is over 21 and that would exclude the kids without actually pointing them out. Is that a polite way around the problem?
ETA: I am not asking to be told something is okay etiquette-wise if it isn't...I just really need help with finding a way if there is one!
