Nanny Needed

I need a nanny for 1 child in San Antonio, one who is willing to work overnight. My schedule varies from week to week, and you would only be needed on the days I'm working. I pref someone who could help out with light housekeeping. After school, duties including helping with homework when needed. The actual times would be 5pm-6:30 a.m. 2 days a week and 9pm-6:30 a.m. 2 days a week. Also other days as needed. My other daughter would be home but can take care of herself. My daughter loves anything having to do with the planets, animals and slime.
