Nanny Needed For 4-Month Old In Kalorama Neighborhood Of DC

My wife and I are looking for a nanny for our 4-month-old son. To start, the position is part-time for 5 hours in the afternoons Monday - Friday. Starting in April, we will need a full-time nanny. Monday - Thursday the hours will be from around 8 a.m. - 6 p.m. On Fridays the hours will be shorter, maybe 5-6 hours that are more flexible. The person who takes the part-time position could certainly become the full-time nanny, but we are also interested in applications from individuals only interested in one or the other. Duties include feeding, playtime and age-appropriate activities, handling baby's laundry, and maintaining/organizing his things (bottles, toys, supplies, etc.).
