A groups of parents who trade off babysitting instead of always hunting down a babysitter and paying $10+ an hour. For example; The Jones's babysit for The Smiths, The Smiths babysit for the Jacksons, and The Jackson's babysit for The Jones's. We can get together, get to know each other, ours kids can get to know each other and hopefully help each other out and save a buck.
