Just wanted to let everyone know about these great playgroups run by the Waldorf school for under 3-year olds. Friday afternoons at the school in Lexington, and Tuesday and Wednesday mornings at churches in Arlington and West Concord. There is free play (with great toys!) then Waldorf teachers sing songs, do puppet shows, and have snack time. It's our favorite drop in playgroup we've found anywhere. See the link above for more details.
