Sex education for nine year olds | Sex Educator

Puberty is around the corner

At age nine, many kids are starting to notice the first signs of puberty – or they will soon. They’re also hearing new words at school and asking bigger questions about bodies and relationships.

This is the perfect time to prepare them before changes begin. The goal is not to overwhelm them with detail, but to give them confidence and reassurance that what’s coming is natural and manageable.

Feeling overwhelmed? Start small

Seeing puberty topics on the horizon can feel daunting. Remember, you don’t need to explain everything in one go.

Mindset shifts to help you breathe

Knowledge is protection: Talking before changes happen reduces anxiety.
Permission to go slow: One small chat is better than silence.
Connection over content: Your child just needs to know you’re a safe person to ask.

Puberty overview (changes happen at different times)

What to teach (with scripts)

Puberty Basics: Explain: “Puberty is when your body changes from a child’s body into an adult’s body. You might grow taller, get hair in new places, or start to smell different. Everyone’s body changes at its own time.”
Periods (First Conversation): Keep it simple: “A period is when blood comes from the uterus, usually once a month. It’s how the body gets ready for a baby – even though you’re too young now. There are different products people use, like pads or period underwear.”
Erections & Wet Dreams: Explain that erections and wet dreams are natural and not something to be embarrassed about. “Sometimes the penis gets hard by itself – that’s called an erection. People with penises might also release fluid at night while sleeping – it’s called a wet dream. Both are natural.”
Hygiene Basics: Encourage regular showers, using deodorant if needed, and clean clothes every day.
Consent in Friendships: Teach them: “It’s only fun if both people want to play.” Practise asking before touching or borrowing things.
Healthy Friendships: Talk about what makes a good friend: honesty, kindness, respect.

TIP. Not sure how to talk about one of these topics? If you’re thinking “how the heck do I explain that?”, don’t worry — you’re in the right place. Just scroll down and you’ll find blogposts that show you what to say, when to say it, and how to keep it age-appropriate. You don’t have to figure it all out on your own — I’ve got you 💛

Tips for talking

Use everyday life: “You’ll need deodorant soon – let’s pick one together.”
Keep answers short and clear.
Use books, diagrams, or videos as conversation starters.
Don’t wait until puberty starts – talk before it happens.

Common parent fears (and reassurance)

“Won’t puberty talks scare them?” → No – early knowledge reduces fear and confusion.
“Talking about periods with my son feels awkward.” → All kids need to learn about periods, regardless of gender – it helps them understand themselves, their friends, or future partners.

What if I do nothing?

If you avoid these talks, your child may face their first body changes feeling scared, ashamed, or unprepared.

Next steps

At age ten, you’ll build on this foundation with more detail about reproduction, consent skills, and body image.
