Kirby reminisces fondly about her mom being the only parent who got out and played with the neighborhood kids. Kirby followed in her footsteps. The kids noticed. "You like being with us!" 

Outdoor play can be for parents and children. It's really important to play outside with kids, not just to send them out and invite neighborhood kids over. Their development will leap ahead -- socially, cognitively, physically, relationally (especially toward the parent playing with them).

But you may not have had an experience like Kirby's. And if you have not seen it modeled, you may not be able to picture it.

Do you have trouble getting your preschooler to cooperate? (That was a joke…of course you do—they're preschoolers!)

One simple change you can make--without much effort, without discussing parenting philosophy with your spouse, without brainstorming rewards or meting out punishments— can make a significant change in how cooperative your preschooler becomes.

And don't tell, but it will probably work on the adults in your life, too.
