Babysitter Needed for my Children

Experience with infants is a must. We are looking for a flexible and reliable nanny primarily for our (currently) 6-month-old son and our 4-year-old daughter. Half the time will be spent solely with our son, and the other half with both children. My scheduled days/hours of work varies which includes weekends approximately once per month. My work schedule is published typically 2 months in advance with 3 month increments. Flexibility would be key in this position.
