When I was a kid/teen, my father would open my bedroom door and let the dog into the room. The dog would jump on my bed and lick my face until I sat up. Worked like a charm.
When we lived in the states, my rule was we left at 7:28 for school; if a kid wasn’t in the car then she was responsible for getting herself to school. In Israel, the rule was if a kid missed the bus then she had to tremp, as we don’t have a car.
