Nanny Needed For My Children - Full-time / Part-time

My wife and I are looking for a sitter to come to our home and help out with our 2-year-old son. My wife works from home so she will always be present but is busy with meetings most the day. The schedule will vary from week to week as I work an irregular schedule but sitter is garunteed atleast 2 days a week. Our son is basically a typical 2-year-old boy .
