Babysitter Needed For 2 Children In Lancaster.

We are looking for an occasional babysitter for varying days and times for our 4- (soon to be 5-) year old son and 7-year-old daughter. We would need a babysitter mostly for Thursday nights for a few hours and during either the morning or afternoon on weekends, but we occasionally need a sitter for other weeknights and some weekend nights. A caretaker with CPR/First Aid training is preferred but background check is required.
