Babysitter Needed for my Children - Now Hiring

We're looking for a reliable backup babysitter for our infant twin girls during the week when our full-time nanny is unavailable. Immediate coverage is needed on August 12, 13, 14 and September 17, 18, and 21 for 68 hours each day. We'd also love to find someone available for occasional weekday coverage, evening babysitting, and weekend help as needed. Experience caring for infants is required, and experience with twins is a plus. You must be comfortable managing two babies independently, be dependable, nurturing, and have reliable transportation. CPR certification is preferred.
