Has anyone organized a co-op? I am working on one now with a few others in my area... our kids are all 5 and under pretty much (1 6 yr old). I am doing a monthly "extracurricular" meet up for those who can't meet more often but want the networking, etc. An every other week to intro something in social studies or science (I think) and a weekly to go deeper into the SS or science that was intro-ed previously. Any tips?
