Let’s be real—when it comes to the first signs of puberty, moms have a lot of questions.
Is my daughter starting too early? What’s normal these days?
How do I talk to her about periods, breast development, and all those body changes without making it weird?
If you’re noticing changes and wondering what’s next, you’re not alone.
Let’s walk through the first signs of puberty in girls, what to expect, and how to support your daughter through this big transition from childhood to adolescence.
First Signs of Puberty: What to Watch For
Puberty is a natural part of growing up, but the signs of puberty in girls can show up earlier than most of us remember from our own childhoods.
On average, puberty begins between ages 8 and 13, but it can start as early as 7 for some girls, especially if you started early or if your daughter has a higher body weight.
Breast Buds: The Earliest Sign
- One of the first signs of puberty in girls is the appearance of breast buds—small, sometimes sore bumps right under the nipple.
- This stage is called “thelarche,” and it’s totally normal for breast buds to show up on one side before the other.
- If breast buds haven’t appeared by age 13, it’s a good idea to check in with your doctor.

Pubic Hair: The Next Step
- Not long after breast development starts, you’ll notice soft, light hair growing on the lips of the vulva and then in the pubic area.
- This is called “pubarche.” At first, the hair is fine and light, but over time it gets thicker, darker, and curlier.
- Pubic hair may spread to the inner thighs and even up toward the belly button as puberty progresses.
Other Early Signs of Puberty in Girls
- Hair starts growing under the arms.
- Sweat glands kick into high gear, so you may notice more sweating and body odor.
- Skin changes—think oily skin, clogged pores, and sometimes acne breakouts.
- Body shape shifts: hips get wider, thighs and bottom may fill out.
- A sudden growth spurt—girls can grow up to 10 inches and gain up to 25 pounds before their first period.
When Does Puberty Happen? The New “Normal”
- Most girls start puberty between ages 8 and 13, with breast buds as the first sign.
- Pubic hair usually starts soon after breast buds, sometimes at the same time.
- The first period (menstruation) typically arrives about 2 to 3 years after breast buds appear, most often between ages 11 and 13—but it can be as early as 9 or as late as 16.
- Girls are getting their first periods earlier now than in previous generations—on average, around age 11.9 in 2000s, compared to 12.5 in the 1950s and 1960s.
Why Is Puberty Starting Earlier for Some Girls?
- Higher body weight, changes in diet, family history, and exposure to certain chemicals in the environment can all play a role.
- Stress and less physical activity (think: pandemic life) may also be factors.
- Early puberty can bring its own set of worries, so it’s important to keep the conversation open and honest with your daughter.

Real Questions Moms Ask About Puberty
My daughter’s only 8 and she’s already developing breast buds. Should I be worried?
No need to panic—puberty can start as early as age 7 or 8, especially if you started early or if she has a higher body weight. If you have concerns, talk to your pediatrician for peace of mind.
She’s noticing hair in her pubic area and under her arms. Is this normal?
Totally normal and one of the first visible signs of puberty in girls. This hair will get thicker and darker as puberty continues.
When will she get her first period?
Most girls get their first period about 2 to 3 years after breast buds appear, usually between ages 11 and 13—but there’s a wide range of normal.
What about emotional changes?
Hormonal changes can lead to mood swings, increased sensitivity, and emotional ups and downs. This is a natural part of puberty, so keep the lines of communication open.
Quick Tips for Moms: Supporting Your Daughter Through Puberty
- Keep it casual: Talk about puberty and periods like you would any other part of growing up.
- Stock up: Have pads, period underwear, and gentle skin care ready before her first period.
- Normalize the changes: Remind her that every girl goes through puberty at her own pace.
- Teach good hygiene: Show her how to care for her skin, manage sweat, and handle new hair growth.
- Encourage questions: Let her know there are no “weird” questions about puberty or her body.
