Talking to Your Preteen About Puberty and Growing Up
The years between eight and twelve are when the questions get specific. Here is how to answer them calmly, accurately, and in your own family’s voice — so the right information comes from you.
Quick answer: Talking to your preteen about puberty works best as a series of small, calm conversations rather than one big “talk.” Between roughly eight and twelve, children’s bodies begin to change and their questions grow more specific. Answer them accurately and without shame, rooted in your family’s values — so the right information comes from you, not the playground.
This guide follows on from my earlier one on talking to your toddler about their body, and leads into the conversations of the teenage years. Think of it as one long, gentle thread that runs through your child’s growing up — not a single, dreaded event.
Why the best source of this information is you
Many children learn about puberty and sex from almost anyone except their parents. Playground talk is, at best, incomplete, and it usually leaves a child misinformed — and without any of the values you would want to pass on. You are far better placed to give your child accurate information and to frame it within your family’s beliefs. Stepping into that role, rather than leaving it to peers or a search engine, is one of the most protective things you can do as a parent.
The window is also earlier than many parents expect. Puberty does not politely wait for secondary school — for some children the first changes arrive at eight or nine. If you plan to have these conversations “when they’re older,” you may find the body has moved faster than the plan.
Puberty by the numbers
Sources: onset ranges — U.S. National Institute of Child Health and Human Development (NICHD); menarche timing — American Family Physician review of pubertal development (2017); duration — peer-reviewed paediatric pubertal-development research.
It is a conversation, not one big “talk”
There is a common misconception that this is a single, daunting, hours-long discussion — a set-piece to be got through once and never repeated. It is not. It works best as an ongoing series of small, everyday exchanges, delivered in manageable pieces as questions come up. Answer the question your child actually asked, simply, and let that be enough for now. There will be another chance tomorrow.
If you feel uncomfortable, a good age-appropriate book on puberty can carry some of the load. You and your child can read it together, which takes the pressure off you to find every word yourself — and gives them something to return to privately.
The questions your preteen is likely to ask
Here are the questions I hear about most often at this age, with calm, age-appropriate ways to answer them. Keep your face and tone even — your reaction teaches your child whether it is safe to come back with the next one.
“What is a period?”
Explain that a period is a natural sign that a girl’s body is growing up and will one day be able to have a baby. This is a good moment to talk simply about bleeding and sanitary products — which also makes it far less awkward the next time such an advertisement appears on television. Boys benefit from this explanation too; it builds understanding rather than teasing.
“What is an erection? What is a wet dream?”
Explain that a boy’s penis is usually soft but sometimes becomes hard for a short while — that is an erection, and it is a normal part of growing up. This is also a natural moment to mention that wet dreams happen on their own during sleep, are completely normal, and are nothing to feel embarrassed about.
“How are babies made?”
Keep it factual and simple, pitched to your child’s maturity. A calm explanation that a baby is made when a man’s and a woman’s bodies come together is usually enough at this stage; an age-appropriate book can help you fill in more detail at the right level when they ask for it.
“What is masturbation?”
Explain, simply and without shame, that it is a normal thing many people do, and that it is private — something done in one’s own space, not in front of others. Framing it as normal-but-private removes the secrecy and guilt that cause far more distress than the act itself, and it quietly teaches the idea of privacy and personal boundaries.
“What does it mean to be gay?”
Explain that being gay means a person is attracted to, or falls in love with, someone of the same gender — and that this is simply one of the normal ways people can be. Keeping your tone matter-of-fact and accepting teaches your child that all people deserve respect, and makes it safe for them to talk to you about their own feelings as they grow. If your own child later shares that they may be gay, my guide on supporting a child who comes out may help.
Open conversation is also a form of protection. A child who knows they can ask you anything is far more likely to tell you if a person or situation makes them uncomfortable. Alongside these talks, teach the simple ideas that their body belongs to them, that no adult should ask them to keep secrets about their body, and that they can always come to you — you will not be angry. If your child seems unusually withdrawn, anxious, or as though they are carrying something they cannot say, treat it gently and, if it persists, speak with a qualified mental-health professional.
Reassuring them their body is normal
Preteens often carry real anxiety about whether their bodies are “normal.” Girls may worry about their breasts, boys about how their bodies are developing — and almost every child worries about changing at the “right” time. The single most reassuring thing you can offer is the truth: puberty arrives at different ages for different people, everyone changes on their own timetable, and there is no such thing as being behind.
The most reassuring thing you can tell a preteen is simple: everyone changes on their own timetable, and there is no such thing as being behind.
Use everyday moments — a scene in a film, an advertisement, a friend’s news — to talk naturally about bodies, relationships, and growing up, so the topic stays ordinary rather than becoming taboo.
How to start — and keep — the conversation
- Use everyday openings. A television advert, a storyline, or a question out of nowhere is a better starting point than sitting your child down formally.
- Answer the question they actually asked. Give a simple, honest reply, then check whether they want to know more. Often they don’t — yet.
- Use plain, correct words. Naming body parts accurately reduces shame and confusion, and makes it easier for a child to describe anything that worries them.
- Let a good book help. Choose an age-appropriate book and read it together; it shares the load and gives your child something to revisit privately.
- Keep your reaction calm. Even when a question surprises you, an even tone tells your child it is safe to come back with the next one.
- End with an open door. Finish with some version of, “You can always ask me anything” — and mean it.
Above all, keep that door open. A preteen who knows they can ask you anything and get a calm, honest answer is far safer and more confident than one who learns to keep their questions to themselves.

Frequently asked questions
At what age should I start talking to my preteen about puberty?
Sooner than most parents assume. Because puberty can begin around eight in girls and nine in boys, it helps to lay simple groundwork before the changes arrive, rather than after. You don’t need one big talk at a fixed age — just start answering questions honestly whenever they come up, and add detail as your child matures. Early, low-key conversations are far easier than catching up later.
What if I feel too embarrassed to have these conversations?
Embarrassment is extremely common and nothing to be ashamed of. You do not have to be perfectly composed — you only have to be available. A good age-appropriate book can carry some of the words for you, and reading it together takes the spotlight off you. What your child remembers is not your polish, but that you stayed calm and did not shut the topic down.
My daughter hasn’t started her period — when should I explain it?
Before it happens, not after. A first period can arrive as early as nine, and a child who is unprepared can be frightened by it. Explain simply that it is a normal sign of growing up, show her what sanitary products are for, and let her know exactly whom to tell and where supplies are kept. Preparation turns a potentially alarming event into an ordinary one.
How much detail is too much for a preteen?
Follow your child’s lead. Answer the specific question they asked, simply and honestly, then pause. If they want more, they will ask; if they change the subject, they have heard enough for now. You are not obliged to deliver a full biology lesson in one go. Little and often, matched to their maturity, works far better than one overwhelming download of information.
My child asked how babies are made. What do I say?
Keep it factual, calm, and pitched to their age. At this stage, a clear explanation that a baby is made when a man’s and a woman’s bodies come together is usually enough. Avoid inventing stork stories — accurate, simple language builds trust and means you won’t have to un-teach anything later. An age-appropriate book can help you add detail when your child is ready for it.
Is it normal for my preteen to ask about masturbation?
Yes. Curiosity at this age is completely normal. Explain, without shame, that it is something many people do and that it is private — done in one’s own space, not in front of others. Framing it as normal-but-private removes secrecy and guilt, and gently reinforces the idea of privacy and personal boundaries that protects children in other situations too.
How do I answer if my child asks what “gay” means?
Answer plainly: being gay means a person is attracted to, or falls in love with, someone of the same gender, and it is one of the normal ways people can be. A matter-of-fact, accepting tone teaches respect for others and, importantly, makes it safe for your own child to talk to you about their feelings as they grow up.
My child seems worried about developing earlier or later than friends. How do I reassure them?
Name the worry and normalise it. Explain that puberty runs on its own clock for every person, that a range of several years is completely normal, and that being “first” or “last” says nothing about them. If a child is markedly out of step with peers or the worry is intense and persistent, a quick conversation with your paediatrician can offer reassurance and rule anything out.
Should I use a book, or just talk?
Both, ideally. Conversation lets you tailor answers and share your family’s values; a good book gives accurate information in words you may struggle to find, and something your child can reread privately. Reading it together also eases the awkwardness. Think of the book as a support to your conversations, not a replacement for them.
My preteen shuts down whenever I raise these topics. What can I do?
Don’t force a face-to-face talk. Many children open up more easily side by side — in the car, on a walk, while cooking — where there is no eye contact and an easy exit. Keep your comments brief and low-pressure, leave a book where they can find it, and make it clear the door is open. Consistency matters more than any single conversation.
How do I keep my child safe online without frightening them?
Frame it as ordinary safety, like crossing a road. Explain that people online are not always who they claim to be, that they should never share photos or personal details, and that they can always come to you — without getting into trouble — if something feels wrong. Pair this with the wider message that no one should ask them to keep secrets about their body. Calm, clear rules protect better than fear.
When should I be concerned enough to see a professional?
Trust your instincts. Passing self-consciousness is normal, but persistent low mood, marked withdrawal, sudden changes in behaviour, or signs that your child is carrying something they cannot say are worth taking seriously. If these last more than a couple of weeks or interfere with daily life, speak with a qualified mental-health professional. Seeking guidance early is a sign of good parenting, not failure.
