Looking For A Nanny For 2 Children

I am currently looking for a nanny to help watch my two young children (ages 3. 5 and 1. 5 years old). I am also pregnant and due mid-July. We need someone to work most mornings, but my schedule is somewhat adjustable. Ideally, we would love to have someone work for approximately 20 hours per week and then be available for occasional date nights.
