I think this episode was great. Periods are not inappropriate for kids to learn about. They are not an adult subject. You literally start getting them way before adulthood. It's a part of childhood for most women. It's something half the population experiences. I am male, and I learned what they were very early on due to growing up in a house with a mom, two older sisters, and one bathroom. And I learned again what the were in more detail in my middle school health class. Young boys should know what they are and as a society we need to stop acting like it is an embarrassing thing. Sydney is like what, 12 or 13? Many girls get their first period way before that. Periods are normal and nobody should be embarrassed to have them. To the person in the reviews that said that boys might look up what a period is and then it will embarrass girls, let me just say that if anyone makes fun of you having having one, they are an absolute loser. This was a good episode, and it annoys and frustrates me that people got angry about this episode being too "adult."
