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

I am looking for someone to watch my kid(s) from roughly 9am-2 p.m. two days a week. I can be somewhat flexible on the hours and the days, but would prefer Tuesday, Wednesday, and/or Thursdays. From 9-11:45, it would just be my 2-year-old son at home. Then, my 4-year-old daughter gets off the bus at our house at 11:45ish so the care would be for two children for the last 2ish hours.
