Sorry, if your title says it, I'm mobile bumping... But where in the cities are you? Also, I think that if you are looking for a preschool, many start between 2.5 and 3.5...
I know of a Montessori Preschool in Minneapolis Uptown that takes children starting at 16 months. It's called Kumi's House Of Children. I don't know exactly what part of Minneapolis you are looking in, but if that area is what you want, then I'd try there at least to start.

Re: Preschool/Montessori MPLS/western suburbs?
All the pre-schools I know of you need to be 2 by September 1st, which it doesn't sound like your daughter will be.
