My girls are 8 and 10, and when they were 4-6, we were totally involved in the playdate dance. They got invited to many, and I felt it my duty to reciprocate back. So I did for the most part. Mostly, the kids enjoyed it, and I didn't mind. BUT. . . if you get into this with multiple friends and have multiple kids yourself, and everyone expects a weekly back and forth, it very quickly can fill up your calendar and become hard to keep up with (especially for a more introverted, anti-overscheduled personality like myself). Then I started to feel like as my daughters got older, THEY should be in charge of their social calendar, not me. And really, they each have a handful of friends in the neighborhood, so their social needs were pretty easily be met the old-fashioned "go out and play" way without all the scheduling. I think parent-directed playdates can be overdone. Little kids are happy playing with most anyone, and big kids need to be guided to make their own friendship and free time choices. So I stopped the playdate madness. Yes, I know I ruffled a few feathers, because we were very entrenched in it, but it all got to be too much. And we are busier with a few activities, and with family, and just plain downtime. Now, if my girls want to invite a friend over, THEY need to ask me, and take some initiative to make it happen. And I know they are choosing people THEY really like to be with, not just the friends I can easily call up because I am comfortable with the mom. I will help, advise, and encourage, but I will not orchestrate their friendships. We've lost touch with some old friends that no longer run in the same circles, schools, activities, etc, but that is a learning and growing experience. Also, sometimes as kids get older they grow apart, even though the moms still feel an obligation to "keep it going" I do tell my kids it is nice to reciprocate playdates, that is what good friends do, and if they like playing with so and so, they SHOULD invite them over here next time. But I don't force them to. I tell them they will get out of friendships what they put in to them. And if I notice a certain friend hasn't invited or called my DD for a year, though my calls/invites her out movies, outings, playdates, sleepovers, etc., it's time to think about the balance of give and take in the friendship.
