Nanny Needed For My Children

I am in Columbus going through cancer treatment at The James (OSU). Right now in radiation that is Monday through Friday for about another 4 weeks. I would need someone that is very reliable to come during my designated appt time to sit with her in the waiting room. Once I am called back radiation takes about 15-20 mins. Sometimes they run on time and other times I have waited up to an hour before they call me back. So watching my child anywhere from 20 mins to 1. 5 hrs each day. I can not have the sitter cancel on me because then I can not get radiation and can cause health problems. My child should be very easy to watch. I can have my child watch tv off my phone during that time. Thank you
