Babysitter Needed for my Children - Full-time / Part-time

We are currently looking for an on call babysitter to fill in on days that our regular nanny is unavailable. You will be responsible for caring for our outgoing and silly 19-month-old. Ideally candidates are experienced babysitters with CPR training and interested in picking up extra week day shifts when our babysitter/nanny is sick or not available. There may also be future opportunities for weekends and date nights. Ideal availability will start in September. Both parents work from home w/ on a cat who naps all day.
