Kids' entertainers like a magician, a bubble man, or a balloon artist is always a hit. This way the parents get to enjoy the wedding and the kids get to be kids without interrupting the events of the night.
1. Coloring activities are the most popular way of keeping kids occupied, which is your goal, because, really, weddings are mostly geared towards adults. Providing them ample opportunity to get creative will keep them (and you) happy. Supply crayons, coloring books, (you can find wedding-themed ones online, or check out these customized wedding coloring books on Etsy ). Paper place mats, with crossword puzzles and mazes, are a great option too.
