Mother's Helper For Brooklyn Family - Morning Hours

We are looking for a mother's helper to assist in the morning hours before our regular nanny arrives at 9 a.m. and for a few hours after. The mother's helper would assist with breakfast/childcare for our two girls (ages 2. 5 and 4 months) while my husband and I are either working from home or getting ready to leave for the office. In addition, the mother's helper would assist with light housework - kitchen/living room clean up and family laundry after our primary caregiver arrives at 9 a.m. Once a week, the mother's helper would go to the grocery store and make a family meal (after the primary caregiver arrives). The mother's helper may also assist with neighborhood drop offs for our older daughter. Looking for someone kind, responsible, detail-oriented, and great with children. Must be fluent in English.
