Sitter Job in Andover, Connecticut

We are looking for after school sitter from 3pm to approx. 5:15 pm Monday to Thursday. Pick up required for pre K son at 3pm, then Kindergarten son and 4th grade daughter get off the bus at 3:20. Homework help and play time with snacks until we get home, usually around 5:15. We are 2 minutes from the school so the driving is short and we have a car seat. We prefer someone who could maybe do extra hours if possible if children are sick or for other reasons.
