Play groups

Now that summer is (almost) here, a lot of us are finding our way to the park to outside to enjoy the sun. In my little neighborhood, a few of us like to take our kids and walk to the park. We do a few laps around the park, then we let the kids play for a while. That's what we do for social interaction and exercise.

Some moms have successful play groups and play dates. I'd like to know all about those.

Do you have them scheduled weekly? Do you call and set them up whenever you want to play? Do you have snacks and games or just let the kids play? Do you rotate houses?

Come on. Give me the goods.
