I'm trying to save money, and one suggestion was to exclude children under a certain age from the reception. I am having a cocktail reception (full dinner, but cocktail style) so I don't think most children would last very long anyway. How do I word the invitation to not offend people, but ask/tell them not to bring children under a certain age? For out of town guests, I'd like to offer babysitting services at my parents house, any suggestions for wording that too?
