We do both! Sometimes during the summer, when the weather is
gorgeous and we can be outside, playgroup is outside, and we have a
mommy happy hour with wine and the kiddos.
Sometimes, like now, when the weather is cold and the days are
short, we plan a MNO (Mom's Night Out) and let our hair down.
All of our activities are really fun and help to incorporate all
of our group, especially the ones that may be pregnant at the
time.
I don't actually have any friends up here that don't have kids,
so I don't even REMEMBER what that's like :-)
