I need a reliable babysitter to look after my two children, ages 4 and 7, on an occasional basis. This would mostly be for evenings when I have work commitments or social events. The ideal candidate should be experienced with kids, patient, and able to engage them in fun and educational activities. Light meal preparation and bedtime routines will be required. We live in a quiet neighborhood and prefer someone who can start around early evening. References would be appreciated.
