Puberty & Body Changes

Tough Talks · about 5 minutes to read or listen · Ages 10–12, 13–15

When their body starts changing and you’re not sure what to say

Your child is growing fast. Maybe they need deodorant, or their voice cracks, or they got their first period. If you never had these talks with your own parents, you might not know where to start. That is very common.

Puberty usually starts somewhere between about 8 and 14, and every child moves at their own pace. Bodies change, and so do moods. It can feel awkward for both of you.

Talking early and often helps. When you keep it light and matter-of-fact, your child learns that their body is normal and that you are a safe person to ask. Otherwise they will get their answers from friends or the internet.

What you might notice

• Stronger body odor, oily skin, or acne
• Growth spurts and bigger appetites
• Breast development, hips, or a first period for girls
• Voice cracking and deepening, and facial hair for boys
• Bigger mood swings or more need for privacy
• Worrying about how they look or comparing their body to others

One sign on its own is often just normal teen life. Look for patterns and changes that last.

Before you talk

• Get your own facts straight so you feel calm. A trusted medical site helps.
• Keep it short. Many small talks work better than one big one.
• Use side-by-side times, like car rides or cooking, so there is less eye contact.
• Have supplies ready, like deodorant, pads, or a razor, so it feels practical.

Things you can say

• Your body is going to change a lot over the next few years. That's normal, and everyone goes through it.
• You can ask me anything. If I don't know, we'll look it up together.
• I put some deodorant in the bathroom for you. It's a grown-up thing we all use.
• Getting your period is a healthy part of growing up. Let's put a kit in your backpack just in case.
• Your voice might crack for a while. It's just your body growing, and it settles down.
• Everyone grows at a different speed. Your body is right on its own schedule.

Try not to

• Teasing about their body or voice, even as a joke
• Commenting on weight or shape, which can hurt body image
• Making it a big serious sit-down, which makes it awkward
• Only talking to them about their own gender, since both need the facts
• Brushing off moods as just hormones, which feels dismissive

If they open up, or shut down

If they open up, answer simply and truthfully, at their level. It is fine to say I'm not sure, let me find out. Keep the door open by bringing up small topics now and then. If you notice very early or very late changes, or your child seems very upset about their body, check in with their doctor.

If they shut down or roll their eyes, that is okay. Leave a good book or a trusted website for them, and let them know you are there when they are ready.

By age

• Ages 10–12: Talk before changes start, using correct body words and simple facts. Keep supplies ready, like deodorant and pads, and keep talks short and calm.
• Ages 13–15: Changes are in full swing, so focus on hygiene, moods, and body image. Give more privacy, and let them know they can still ask you anything.
• Ages 16–18: Most changes are done, but questions about bodies, health, and self-image can remain. Help them start handling their own doctor visits and health care.

Where to get more help

• Your child's doctor or school counselor. A good first call. They know your teen, can check for health or learning issues, and can point you to local help.
• HealthyChildren.org from the American Academy of Pediatrics. Pediatrician-reviewed articles for parents on puberty for boys and girls.
• KidsHealth from Nemours. Easy-to-read articles on puberty and growing up, with sections for parents, kids, and teens.
