They're counting. It's part of this game we play in the front yard. Each time we play the rules change, bend or it becomes more complex. I chase them around the yard as they try to get to the safe zone (any spot with mulch). They work together as a team to keep each other safe..{ big boy little } pulling me back to keep me from grabbing his brother. If I catch them, they sit on the step until the count of 10 then they are back into the game. It's simple but they love it....and I love their giggles as they run. Win-win I'd say.
