Other than wooden blocks, palumba.com has a good example of the kinds of toys Waldorf families keep around. We have corn brooms big and small, wonderful wet on wet watercolor supplies and their gorgeous knitted wool food that was worth every penny. We also love hand puppets here.
This year, I bought my four year old a metal slinky, a glass straw, canvas ballet shoes and tickets to see The Nutcracker with her grandma. She pretty much has enough stuff. My son (were we in the same due date group?) is getting a Plan Toys ball box and a Guidecraft screw block, along with a glass straw.
I run the Frontier Wholesale co-op in February, May, August & November
