How to say NO KIDS politely
We are hosting a 60th birthday party for my father. I have 2 kids, I also have 2 nephews. We would like to say NO KIDS to our guests (who have mostly toddlers), however our kids (whom are all 9-12 yrs) will be present for their grandfathers party. Is there a polite way to say no kids, when yours will be there? I have found that addressing the invitation to just the parents does not work and most people overlook who it was addressed to. HELP!
