Unfortunately, I don't, but I'm looking in the same general areas-
White Plains, Mamaroneck, Larchmont, Pelham
(I live in White Plains, work in Pelham)
I'd love to learn along with you!
I'm considering trying to find a nanny and split the cost with a friend who's also in white plains and due any day. It might be cost effective, but I have no idea how to go about finding someone reputable!
