I am aslo a pagan mom, with a christian husband, lol. We attend the UU church in Hagerstown MD and our pagan group is called the Queen of Heaven Circle. It's a great group. We also started a chapter of SpiralScouts for the children.
My kids know both, actually very basic with both. My husband is not very active in his church and I respect his wishes and tell the girls some, but not in detail till they are older.
I have the circle Round book and CD and love it. My girls love the songs.
Blessings and Luck,
