I have 2 preschool age daughters, Phoebe (4) and Coco (3), and very much understand your trepidation. The families i have met through this coop are warm and welcoming, and the seasoned families with older children have helped answer many of my questions along the way. I also checked out every book from the library on home schooling, and especially liked books by Linda Dobson. Two books that pleasantly surprised me were "The Homeshooling Option", and "The Everything Homeschooling Book".
Summer is always a busy time for us, but we hope to make it to the park day this week. There are quite a few other families with preschoolers, many of whom my girls have built friendships with. Hopefully we will meet you and Imala on one of the park days.
