Babysitter Needed for my Children

We are seeking care for one toddler and three older children. The older children only require supervision, the primary role will be watching the toddler. My shifts vary from week to week. I would like to find someone to use at least once a week. On the weekdays, the older kids go to school from 9:00-4:00 and ride the bus back and forth to our home. They would need help with breakfast, getting to the bus stop, and then care in the afternoon until my spouse or I get home from work. Some days this may include more hours and bedtime.
