Challenging Shot

I didn't have a good idea going into this one. I was thinking maybe something with water droplets, or maybe a series of jumps. In the end, I opted for the following pictures. What is more challenging than capturing three little kids (ages 2, 3, and 4) looking in the same direction at the same time? Especially on Black Friday. At the fourth store (5th if you count the restaurant). Over an hour into the last store - a suit store (I think you are getting my idea here).
