Found these gems on style me pretty a while back and I love their ideas. We'll have a handful or two of kids at our wedding so a their own table/activity area would be great!
These look so fun, paper crowns, adorable hand puppets and crayons, whats not to love? The flowers aren't so practical, maybe some cute pinwheel bouquets instead, and I'd probably go for a craft paper table cloth so they can draw on the whole thing. {fun fact:we love going to restaurants like jack astors where you can do this.. we always turn ours into a massive work of art and have even kept a few}
Also maybe some board games/activity books/little things for them to do like a photo scavenger hunt.... all the grown ups are going to be jealous!
