My daughter is 4. Yesterday she told me in school, her classmate pee in class. She asked me to guess who he was and then told me that when he pee, something sticks out and it's straight. I just told her that he's a boy and he's different from girls. Should I have talked more? Is this the right time to tell her the difference between boys and girls? How did you start talking about it? So far, I've only told her that her body is her own business and only those who take care of her can touch her when she takes a bath or goes to the bathroom, e.g. mom and dad and our helper.
