I'm looking for a great on-call/ back up babysitter for 2 children. Some light meal prep is needed & we have a large dog. After school duties include homework help when needed & playing with the children. Specifically looking for 4-7 p.m. on the weekdays & then as needed availability on a weekends. No specific day as we have a regular part-time nanny but need fill in help with she is not available and don't want to have ad hoc help!
