Earlier than you probably think. Girls now commonly start their periods as early as age 10, so even if your daughter looks as though she's nowhere near puberty, her schoolmates' accounts may confuse and upset her if you haven't given her the basic information first.
She needs two things from you: first, the physical details of menstruation, and second, the security that when her period does begin (or her best friend betrays her by getting her period first),
She can tell you about it without having you get embarrassed or weepy on her. You might want to start this conversation off (or simply let her know that you're willing to have it whenever she wants) with a casual question or remark: "Do you know if any of the older girls at school have started their periods yet?" Or: "You know, when I was your age, I didn't understand about periods and I felt too embarrassed to ask anybody."
Another useful approach for a child who's reached the age of 10 or so is to give her a good, readable children's book on puberty and sexual development. Before buying, look it over yourself to make sure you like its approach. Then put the book in your child's room, where she can look at in private, and casually tell her that you've left it there for her to look at if she wants to.
You can be sure the book will be read, and it may ease her fears and help her feel more comfortable about talking to you about sexual issues and feelings. A good choice would be Where did I come from? by Peter Mayle. Books for parents looking for guidance on the subject include How to talk to your child about sex by Michael and Terri Quinn and What is love? Sex education for children by Patrick Berry.
Boys may notice the erections of other boys (even babies), wonder about their own erections and physical responses, and hear "boner" jokes or other crude references at an early stage, so it's a good idea to explain erections even to very young boys in a low-key way, making sure they understand that there's nothing shameful about a natural body response that they often have no control over.
This should be easier if you've used the correct terms for body parts from the beginning; if you haven't, start getting your child comfortable with saying "penis" and easing him away from the euphemistic terms he's used until now.
Boys begin to have wet dreams when they reach puberty, usually between the ages of 9 and 15. A boy's first ejaculation may occur during a wet dream, and when he wakes up, he may not realise what happened.
Thus it's important to let your son know well before puberty that wet dreams are a normal part of growing up and nothing to be ashamed of, that he can't control them, and that ejaculation is just a physical sign that he's growing into manhood.
Talking about masturbation is embarrassing for both you and your child, but it's important to let her know that there's nothing shameful or abnormal about masturbation. By this age, your child should be long past touching herself in public, but both boys and girls may continue to masturbate in private, some of them quite often. Your child may feel guilty about this unless you reassure her that it's not only normal but healthy to have sexual feelings.
By being as inquisitive as you can, without tipping off your child that you're snooping -- at this age, children absolutely don't want to feel that their parents are looking over their shoulder. At school, ask the teachers exactly what they're teaching at each class level. (When and how do they discuss the reproductive system, sexually transmitted diseases, sexual harassment, and so on?) If they use textbooks or handouts, read them yourself.
You probably worry about what comes at your child on the Internet, but watch her television programmes, too. Pick up the magazines she's looking at.
Be aware of what registers at her eye level on magazine stands, particularly the ones that hold adults-only publications. If you can stand it, listen to your child's favourite radio stations for a while.
You'll probably see that from school age on, children are inundated with sexual references -- most of them sniggering, disrespectful, or misleading. The more you know about what your child is seeing and hearing about sex from other sources, the better equipped you are to make sure she knows what you want to tell her.
Unfortunately, she probably does. She's likely to be hearing or reading references to AIDS and other sexually transmitted diseases in the news and from her schoolmates. You might as well make sure she's getting information that's accurate. And answering her questions matter-of-factly is one more way of reassuring her that she can trust you to discuss sex calmly with her.
If she's 6 years old, no. However, you'd be wise to prepare yourself for a question or conversation about oral sex, especially since it continues to be a perplexing subject for children in school. It's not too early to start talking to your child about the important connections among sex, love, and responsibility. You may want to explain that kissing another person's private parts is another way of having sex; that even though a girl can't get pregnant this way, it's possible to transmit dangerous diseases through oral sex; and that oral sex, just like the other kind, entails feeling love, commitment, and regard for the person with whom it's performed.
