Is it normal for a typical 4th grader to know about sexual stuff?
I am living with my family, which includes my sis. She is currently in 4th grade, same as her friend. They are studying the same school, hang out a lot. However, once, my sis told me that her friend knows a lot about sexual stuff. My sis oftenly talks about that with her friend, but I think that it is influencing her the wrong way. So, is it normal for a 4th grader to know about that kind of stuff? I mean, like, isn't the friend to young to know that?
