Young family of 4. We have 2 sweet daughters that are the best kids ever! Not just saying that lol.
Play, feed, and uphold daily schedules, ie, naps, quiet times, getting to and from school (walking distance).
My wife and I are planning a trip out of the country and we live with my in laws. At least one of them will typically be home and be available to help in some capacity while you are there, but we felt hiring a nanny like yourself would be best to share the load.
