Not being a parent or someone who has spent much time with kids, I need advice on how to entertain some children who will be present at our reception. We'll have about 5 children ranging in age from 2-7, and most of them are known to be extremely high-strung and one of them is downright destructive. Due to their ages we won't have a separate kids' table, they'll sit with their parents (but most of the parents are in the BP). I want the parents to be able to have some fun but I don't want the kids running wild, knocking things over, etc. I was thinking about bringing a basket full of kids' activities but crayons or other coloring implements are out of the question, as I wouldn't want to risk them coloring on the floors/walls/tables which some of them do in their own homes. Any ideas for activities that would be neat but keep the kids entertained and calm?
