Hire an Event Sitter! I am the owner of Your Event Sitters, LLC; and enjoy the idea of having an on-site babysitting/entertainment service for children at adult events. We provide activities for children with age appropriate games, puzzles, arts & crafts, and so much more! We alleviate the stress of "mommy guilt" for leaving the children behind, allowing parents to bring them along for us to tend to on-site while they enjoy a family friendly event!
That's a great idea!
