Mother's Helper Needed 3 Times A Week

Hi, we live in Washington, DC and are looking for a "mother's helper" for three afternoons each week - Tuesday, Wednesday and Thursday from 3:30-5:30. You would come over and help take care of our 2 and 6-year-old boys, either by playing with one/both of them in the house or taking them outside to the playground, library, park, etc. The older boy has ADHD and is very active. We are looking for someone who is energetic and patient and will work with us to use positive language. Wife and husband both work from home and would be in the house during care (mostly upstairs but maybe downstairs to prepare dinner, etc.).
