Babysitter Needed

Seeking a babysitter in Fairfax, VA for 2 children (1 & 3 years old) while mom works from home. Some days, I may need help with my older children (ages 7 & 9) when they are not in camp. These days will be identified in advance and compensation will be higher to reflect the number of children the babysitter is responsible for. This is a temporary role backfilling another regular sitter. Hoping you can start immediately!
