Sittercity hiring for Occasional sitter for when son is sick. jobs in Harrisonburg, VA, US

Hi! My family consist of me, my fiance, my son, and my puppy. My son is 18 months and puppy can be put in the room if needed, he is a shipoo and usually lays around all day, he is 3 years old.
I am looking for someone to watch my son if he is ever sick. I am a graduate student and I have a graduate assistantship and my fiance works so when he is sick and I cant send him to daycare, I would like to have backup.
Whenever needed, the schedule would be Tuesday-Thursday 8am-5pm (the time could be flexible depending on the week)
