I've got to say, what Nannyde describes sounds like it would make the lives of a lot of the other providers here much easier, but I've had several sets of kids over the years who met here and have remained the best of friends, many of them now are in junior high and high school, so the no interaction thing wouldn't have worked very well here
. It's very satisfying to know that I had at least some small part in creating some lasting friendships.
