Babysitter

I'm looking for a great nanny for 1 19-month-old healthy little boy! Our current aupair is leaving later this week, and our new one doesn't start until later in August, so we are hoping to find someone who could cover the transition time. We'd like to avoid having a revolving door of people, so please check the hours that we are looking for. Thank you very much! We're in a good location , close to the Metro, nice area for walking and playing outdoors and going to museums if you'd like!
