Babysitter Needed for my Children

We are looking for a part time nanny for 1 child in Chevy Chase, DC. Pick up from school at 12 M, W, F. You can walk, bus, or drive back to our home or stay out for the day at the multiple playgrounds near the school. My husband works from home on Mondays. We have a large, old dog. No dog care required. My son is 2. 5yo. Im hoping to get him potty trained at the end of summer, so he might still need help with that. He still naps, but can nap anywhere (stroller, bed, car). He is very physical and loves playing outdoors, at playgrounds, with balls.
