One of my Specialties is relocation real estate.
For what you are considering, I would recommend the Westport area and parts of Waldo. There are many great shops, restaurants, and grocery stores! Not to mention both neighborhoods are not too far from the Power and Light District (which features concerts at the Sprint Center often), and the Kansas City Plaza (where there are tons of well known clothing stores and restaurants as well!) I would say that these neighborhoods can be Kid Friendly but again, you would get a better sense after visiting the areas. Also there are some townhomes that are on the newer side as well as updated homes that have great character if your interested in looking!
