What is the protocol for a dad taking his daughter to a public restroom? Does she go into the men's room with him? Sorry if this sounds dumb, but I've only ever seen mothers taking their children into the ladies room with them and I'm wondering if guys ever take their kids into the mens room (and if so what to do about all the exposed man parts), or do they go into the ladies room with their little girls and apologize to the grown women...?
