Talking to Your Child About Their Changing Body

Navigating body changes in puberty can feel confusing for both kids and parents.

As your child starts growing taller, gaining weight, or noticing new physical changes, it’s normal to wonder what to say—and how to say it in a way that builds confidence instead of embarrassment.

In this short video, Dr. Katie Loth, licensed clinical dietitian and WithAll Expert Advisory Panel member, shares how to talk to kids about puberty and body changes in supportive, shame-free ways.

Start With General Conversations About Puberty

When your child’s body starts to change, avoid commenting directly—like, “You’re getting so tall!” or “You’ve put on weight.” For many kids, even well-intentioned remarks can feel uncomfortable.

Instead, start general conversations about puberty and body changes. You might say:

“Puberty is a time when everyone’s body changes in different ways—growing taller, getting stronger, or changing shape. It’s all part of how our bodies grow.”

Framing the topic this way helps your child see what’s happening as completely normal and gives you a natural entry point for more specific talks later.

Keep It Ongoing, Not One-Time

If you’re wondering how to discuss puberty with your child, think small and consistent. A single “big talk” can feel overwhelming for both of you. Instead, offer short, casual check-ins as your child’s questions come up.

You might say:

• “There are a lot of changes that happen around this age. What have you noticed or heard about puberty?”
• “Do you have any questions about what’s happening with your body right now?”

Keeping the door open for future talks shows your child it’s safe to ask questions anytime.

Try a Shared Journal for Sensitive Topics

Some kids feel embarrassed asking questions face-to-face about puberty or body changes. A shared notebook can help. Encourage your child to write down questions, and you can write responses later.

This approach removes pressure from the conversation and gives you both time to think. It’s a great way to show that no question is off-limits.

What to Say

When you’re talking to your child about body changes, try language that’s reassuring and open-ended:

• “Everyone’s body changes in its own time. There’s no right or wrong pace.”
• “Your body is doing exactly what it’s supposed to do.”
• “You can always come to me with questions—even if they feel awkward.”
• “It’s okay if your body feels different right now—that’s part of growing up.”

These small phrases reinforce that your child’s experience is normal and that you’re a safe, trusted guide.
