Week of sitter care for a baby and a toddler - Full-time / Part-time

Hi - Two families (each with 1 young child) vacationing together and looking for another pair of hands around the house. The goal is to have someone to look after the kids, allowing adults to go out to lunch, work from home without interruption, etc. But parents will be in the vicinity regardless. Diaper changes and playground time expected. Just trying this out, should be a reasonably laid back job. Elder kid (almost 2 years old) might be a bit clingy with parents, which we'll deal with together. Experience with babies (6 months old) also necessary.
