Depending on where you are in Prairie Village, there is Pete and Repeat at about 78th and State Line. My kids are way past that but when there were little there was one in Olathe, (Not Children's Orchard, it came along later) that was outstanding. I also would hit garage sales. Sometimes it's a lot of junk, but I also hit on some great deals. *Gymboree at a fraction of the cost.
Good Luck and welcome to the area.
