No not really, its nobodys business if the daughter doesnt want it to be. it also depends on the relationship between father and daughter, if they are close and she feels comfortable with him knowing then its fine, but otherwise only the people she wants to know has to know
No I would not think you would need to know when your daughter period is. Maybe you can just tell that sh is being extra cranky. If it was like the first period or just got it the mom mighh tell dad hey our daughter finally got her period...beyond that no none of dads business.
