Welcome to the neighborhood! We are recent relocators as well. Our daughter is too young yet for school but we have bounced around the Waldorf/Montessori (basically alternative) school options. I haven't heard of any in-home programs, but Mequon has a Montessori school that's easily found online. If you haven't already, pop into the MDC board for Montessori - there might be connections there to be made. I'll be watching to see if anyone responds to this post and will certainly let you know if I find anything. I'm wondering if there might be something further north (Cedarburg or Grafton). Good luck!
