We are located in La Jolla. We are looking for an afterschool babysitter for our three kids ages 5, 7 and 11 from 3-6pm. Duties would include picking up from school and bringing kids home and or to their scheduled activities. Most of the time it would be two of the three as one parent will be bringing one child to a different activity. Compensation is $30 per hour. We would require someone with a car and clean driving record. We would prefer someone that is open to staying for a date night once every other week.
