You might not be emotionally prepared for nine-year-olds to have breast buds, but it is perfectly normal. Just as in so many other corners of the world of parenting, our experiences are not their experiences.

This is especially true for puberty: your timeline will almost certainly not be their timeline. Reading some recent research, or even just looking around at classmates, will reassure you of this fact.

It’s easy to confuse the way a child looks with their chronological age. We’ve all accidentally babied a kid who looks very young for their age or done the exact opposite, incorrectly assuming a level of maturity in a kid who looks particularly old. As the onset of puberty has marched earlier and earlier, girls especially look older.

But they’re still young — chronologically and mentally. They may still love imaginary play or cuddling while watching an old (almost certainly animated) movie. It’s our responsibility to treat kids according to their chronological age, because that’s emotionally and socially appropriate. Do your best to avoid falling into the trap of treating a more mature-looking kid as if they are more mature.

While openness and honesty within a family can be massively valuable, this is a great moment not to share all of your feelings.

Some parents are surprised and maybe even scared to see the beginnings of puberty. It marks the start of a path to sexual maturity and that feels incomprehensible. If you’re going through this thought process, discuss it with other adults — privately and not in front of your kid.

If your kid is feeling OK about their changing body, the last thing you want to do is rock the boat with your baggage. If they’re feeling worried or confused, you definitely don’t want to add your crap to their worries.

The goal is to validate your kid, open the door to ongoing conversations, and give them little snack-size pieces of information.

It might sound something like this: Is your clothing feeling comfortable these days? Is there anything new you’d like to try? I’ve noticed that some kids in your class are wearing camisoles or bras — is that something you’d be interested in?

Sometimes you need to be more direct, because there is basic information your kid needs to learn from you. Things like: I’m not sure if I told you this, but it’s normal for breasts to grow only on one side or the other at first. You may have noticed this: underneath your nipple is something called a breast bud and it might be a little sore. That’s totally normal! Some people may have breast buds and some may have nothing yet. Both are ok.

You might get some tough questions from your kid:

Is something wrong with me?

Is this weird?

Do I have cancer?

Can we make it stop?

If you’re not sure how to respond, try gently asking questions in return, like: What makes you say that? Where did you hear that information?

These will help reveal the source of the feelings. Don’t assume you know where these questions are coming from — remember, their experiences are not your experiences.

Some loving and supportive ways for your kid to feel heard without giving them false or misleading information include responses like: It’s normal to feel confused. Let’s reach out to your pediatrician to check in. I don’t have all the answers but I’m always happy to hear your thoughts.

The onset of puberty and the onset of active sexuality are on two very different time frames, especially as the start of puberty has moved earlier.

Your nine-year-old is still your nine-year-old, so keep doing what you’ve always done to have fun together. Breast buds don’t change the fun of running around or snuggling before bed.

If you start backing away from your kid, cease being affectionate or distance yourself because of her changing body, she may internalize your discomfort and feel rejected, which is the last thing you want her to feel.
