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

We are looking to replace our longstanding incredible nanny who has been helping us with our two children for the last 3 years! We have a son who is almost 4 years old and a daughter who is almost 1-year-old. The majority of the time, the nanny will be focused primarily on our daughter while I handle my son. Occasionally, after getting to know our 4-year-old we would hope to tap you for one off babysitting jobs for him here and there! We do have 2 (extremely friendly) cats--something to consider if you're allergic!
