You can fill in your nanny job however you want. Maybe you'll babysit every Wednesday afternoon or all day on Fridays. Set it up in a way that suits you best. For example, play games with the kids, do crafts, bake something, or go outside. Watching a movie once in a while is of course also fine ;-) You get to decide what you are going to do and you just coordinate it with the parents. After each babysitting shift, you will receive your earnings paid out to the exact minute via the app.
