We are new to the area, and have a first grader, so I don't know what resources are for younger kids, but our dd is in first grade at Emerson Waldorf in Chapel Hill, and I KNOW some families of younger ones do play groups, etc. in the wider area. You might try calling the school for information on local play groups. They're super friendly! 919-967-1858 Good luck!
I'm also a 1st grade parent at EWS, and I highly recommend contacting someone in the Triangle Home Nursery Association. DD attended Morning Song, and I can't sing Ms Joya's praises enough! I'm sure she or someone else would have some ideas. Good luck!
