School Routine

How in the world do you change a child who likes to stay up all night? She Stays up late Doesn't want to go to bed early. She Does however Get up pretty early in the mornings. She starts Kindergarten next Wednesday. I am Really Worried about her not being able to focus because she hasn't had enough sleep. I just Need top be able to stick it out another week I guess. Maybe school will wear her out enough to sleep at night one can only hope. :)
