The waiting game(s)

I am not a patient person, so I get it when toddlers are bored in doctor's waiting rooms, grocery store check out lines, or restaurants before the meal is served. My Iphone and the toddler-friendly songs, games, and video apps have come in handy more than a few times. I also resort to keeping a small collection of new dinky cars or other items I can pull out of my purse in an emergency. When I saw this little kit I couldn't resist sharing.  What tricks do you have to keep your toddlers happy in a pinch?
