I've been a fan of the site ModMama.com for a few years, but didn't think to check their site when I was looking into eco-friendly toys. We have a few of the toys they sell (my girls love the cutting food box, and I think the toaster may be under our Christmas tree in a few short weeks) -- it really is a comfort to know that the paint is lead-free and that the toys are solidly built from natural materials.
If you know of other sites that feature eco-friendly toys, please drop me a line.
