How to keep four kids busy

I got this workout DVD, recommended by my sister-in-law, called Shred by Jillian Micheals. I use it when I don't want to get up early to jog. I really like it. My kids love it, too. All four of them stand around me and exercise. I thought it was so funny that I put in the DVD to show Josh and go this great idea. Use it to keep my kids busy before Lunch. It also wears them out and makes them extra tired for nap and quiet time! My kids are so cute. Notice how Olivia has her Cinderella slippers on.
