Babysitter Needed For 3 Children

We are looking for a great babysitter for 3 children d. We would prefer someone who could help out with light housekeeping (meal/toy clean up). We would prefer a babysitter who does not smoke and who is CPR certified. Every Wednesday from 11AM-4 p.m. care for our 6-month-old and 2-year-old. My 8-year-old would need to be assisted getting off the bus right at corner of our house at 4 p.m. Mom would be home around 5 p.m. My 6-month-old is easy going but we would love structure for her development. My toddler is very energetic and fun loving. Looking for someone to keep him entertained on a physical and educational level, as he loves to learn and play. My 8-year-old is self sufficient and a great big sister. She would just need to be greeted when getting off bus. She can then start homework.
