We have three children. We typically would like a sitter on the weekends and evenings as it will give myself and husband time to do things together and have more date nights. This would also include some weekend travel.
The sitter would only need to keep kids entertained and feed them their meals will be partially or completely prepared already. They will nap and snack as needed. Maybe light cleaning which only include messes made during sitting time nothing else.
East indy and schedule includes weekends and evenings and some overnight.
