I'm a single mom with a 5 year old daughter. I work 6 days a week and need someone to watch her when she gets off the bus after school till I get home from work.
Get her off the school bus, make her dinner, get her bath done, maybe play games or watch tv then put her to bed by 730 or 8pm.
There would only be a few hours of actual child care. The rest of the time would be the sitter watching tv or doing whatever they wanted while my daughter sleeps as long as they don't leave the house.
