Babysitter - Full-time / Part-time

We are looking for a part time nanny to start with us in August to help with our 2 and 1-year-old until our twins arrive (anticipated October/November). The two older children will be at daycare and preschool so to start we are looking for someone to help in the evenings between 4-7p. Once the twins are here we are looking for someone full time during the week days. We would prefer someone who could help out with light housekeeping and cooking. Please be comfortable with pets.
