The reason I ask is that one of my sixth-graders at church was in an unusually sour mood last night; very out-of-character for her. She is normally a very polite, calm, obedient and chipper girl. Last night she was irritable, ornery and short-tempered, and she kept squirming around. I think her Big Moment may be coming up.
So anyway, is PMS something that only girls who have had regular cycles for a while experience?
I note the episode of King of the Hill where Connie got her first period; she was pretty hateful to everybody for a couple of days leading up to the Big Moment. Of course, King of the Hill isn’t exactly an unimpeachable source when it comes to pediatric endocrinology :D.
