Babysitter Needed for my Children

Looking for help on the weekends for a couple hours with our 2 kids, a 1-year-old boy and 4-year-old girl. The caregiver should prepare activities, play games, help with changes, and prepare children for naps. This position is more like a mother's helper position for several hours for one or both weekends. One parent will be always present and nanny would care mostly for one child at the time, occasionally both.
