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

We have a 1-year-old and a 8-year-old, the oldest goes to day camp and is gone till about 6:30 so he wont need to be watched our biggest worry is finding someone to watch the little one. Someone that can feed him, change diapers, lay him down for naps, walks etc. I leave around 6 a.m. but my girlfriend does not leave until around 10:30-11 most days. We only need someone for Tuesday-Friday 10:30-4:30/5:30 as I sometimes get off later than other days
