I live in Liberty and love it. The school district is top notch - not a bad elementary in the bunch. While my kids are in elementary school (Lillian Schumacer), I have friends who love the following preschools:
Second Friends (in the 2nd Baptist church just off the Square)
Second Baptist Church, Liberty - Home is the church URL 816-781-3882
the preschool at Pleasant Valley Baptist Church church URL is
www.pleasantvalley.org
St. Stephen Lutheran Pre-school 816-781-6994 (neighbor teaches there - friends love, love, love this school)
Liberty Montessori 816-781-6295
Hilltop Preschool at Liberty United Methodist Church 781-5942
We live in the Clay Meadows subdivision which is in south Liberty on 291 - basically the farthest away in Liberty you can be from the airport and still be in Liberty. It takes me 25-30 minutes to get to the airport, but 10-15 can be crossing Liberty. If you live on the west side of I-35 you can be to the airport in 15 minutes.
If you/husband is not working in Kansas City proper then you may want to avoid the west side of I-35 which is technically Kansas City but is in Liberty school district. If you live or work in Kansas City you will pay a 1% earnings tax. If you don't work or live in Kansas City then you can avoid that tax. So if the work is in KC then it doesn't matter where you live, you'll be taxed. If you work in Liberty or North Kansas City for example, and choose to live in KC, you'll still be taxed.
From where in Ohio are you moving? I grew up and all of my family is in Greenville OH just NW of Dayton.
