A group of us have a Cloth Diaper Meet-up every Saturday that generally turns into an attachment parenting Mama hang-out. We meet at Sugar Snap Consignment, which is in the Staples shopping center. We meet at 10am and generally hang out for a few hours.
Attatchment-parenting minded people new to Charlottesville might enjoy the Holistic Parents Network and/or Birth Circle.
Not incidentally, Sugar Snap sells new and used cloth diapers and baby carriers, and is a very breastfeeding-friendly place!
