Puberty used to feel like a much shorter, more predictable chapter. Now it often starts earlier, stretches longer, and shows up emotionally before many of us expect it. That shift has changed the parenting conversation in a major way.
We wanted to understand what is actually normal, what deserves attention, and how we can support kids without making an already awkward season even more loaded. Dr. Thais Aliabadi and Mary Alice Haney talked through the whole landscape with Dr. Cara Natterson, from the first signs of puberty to screens, stress, social media, gender conversations, porn exposure, and the pressure kids are carrying today.

Getting Oriented
How did your work around puberty education begin?
It started in a very practical way. I was in pediatric practice, answering the same questions over and over, and realized families wanted clear, accessible information. Writing became a way to get those answers into more homes. Over time, that work evolved into a much bigger mission: making puberty less mysterious, less shame-filled, and far more normalized.
What makes Dr. Natterson’s approach so useful is that it is not alarmist. It is honest, grounded, and very aware of how much parenting has changed. Many of us were raised in homes where periods, hormones, body changes, and sexuality were either brushed aside or wrapped in embarrassment. Now we are trying to do better, often without having had great models ourselves.
What if we feel like we already handled puberty conversations the wrong way?
The first piece of reassurance is simple: we need more grace for ourselves. There is no perfect script, no magical one-time talk, and no parent who gets every moment right. The goal is not perfection. The goal is openness, repair, and continued conversation.
That matters because many of us still think of puberty as one conversation we somehow missed. In reality, it is a long series of smaller conversations. If we have not started yet, we can start now. If we stumbled, we can circle back. If we said too much, too little, or brought our own discomfort into it, we can still reset.

What Puberty Actually Is
When does puberty start now?
One of the biggest changes is timing. The average age of entering puberty has moved earlier than what many of us learned growing up. For girls, the average start is now often between ages eight and nine. For boys, it is commonly between nine and ten.
That does not mean every child starts then. There is still a wide range. But it does mean many adults are waiting for signs much later than they should.
What counts as the start of puberty?
This is where a lot of confusion begins. Puberty does not begin with a first period. That is a midpoint marker for girls, not the start. The earliest sign is often emotional and behavioral before it is clearly physical.
Dr. Natterson shared a line from a pediatric endocrinologist she loves: the first sign of puberty is a slamming door. That image works because puberty begins in the brain. Signals from the brain trigger the ovaries or testicles to start producing sex hormones. Those hormone levels rise and fall in waves, and kids feel those swings before they understand them.
So the first thing we may notice is not breast growth or a deeper voice. It may be intensity. More privacy. Bigger feelings. Faster irritation. More sensitivity. More shutting down.
Why does puberty feel so emotional?
Because hormones are not arriving in a smooth, organized stream. They surge, dip, and surge again. Kids experience those highs and lows in real time without the language or maturity to interpret them. Sometimes that looks like overreacting. Sometimes it looks like crying more easily. Sometimes it looks like laughing harder than the moment calls for. Sometimes it looks like silence.
That is why it helps to stop asking whether a child is being dramatic and start asking whether they may be overwhelmed by sensations they do not yet know how to manage.
Girls and Puberty
What are the first physical signs of puberty in girls?
The most common first physical sign is breast budding. This usually starts as a small amount of tissue under the nipple. It can happen on one side first, and that asymmetry is very common. It can even seem to appear and disappear for a while. Families often panic, but this is typically normal development.
As puberty continues, girls may have:
- Breast development
- Mood swings or heightened emotional expression
- A growth spurt
- Weight gain and more curves
- Some voice deepening
- Eventually, their first period
An important detail here is that girls usually continue growing until about two years after their periods become regular. So the period is not the beginning of the story, and it is not the end either.
Are hair, acne, and body odor part of puberty?
Not exactly. They often show up around the same time, but they are driven by a related process called adrenarche. That comes from hormones made by the adrenal glands, not directly from the reproductive axis that drives puberty.
This is a helpful distinction because kids can get pubic hair, acne, or body odor without truly being in puberty yet. And on the flip side, a child can move through part of puberty before those other features show up. That mismatch can confuse families, so it is worth remembering these processes often overlap but do not always move in lockstep.
Why are so many painful periods dismissed?
This was one of the most important parts of the conversation. Painful periods are still too often minimized, especially in adolescents. We have inherited a culture that taught girls to tough it out and assume suffering is normal. It is not.
If a teen is doubled over, missing school, vomiting, unable to function, or clearly incapacitated by her period, that deserves medical attention. Conditions like endometriosis can begin young, and early dismissal delays diagnosis and treatment.
The same goes for hormone patterns that may suggest PCOS. Acne alone is common in adolescence. But when it appears alongside irregular cycles, excess facial or body hair, hair loss, weight changes, or insulin resistance, we should widen the lens. For families looking to better understand what hormonal care can involve in adolescence, this guide to a first gynecology appointment can help make those conversations less intimidating.

Boys and Puberty
What are the first signs of puberty in boys?
The first physical signs are usually growth of the testicles and penis. The problem is that most families are not going to notice that, nor should they be checking for it. So boys often enter puberty before anyone realizes it.
Later signs become easier to see:
- Increasing lean muscle mass
- Broader shoulders
- A more significant voice drop
- Less baby fat
- Eventually facial and body hair, acne, and stronger body odor
Again, those last three can be influenced by adrenarche and may not line up perfectly with the rest.
Why do boys often get so quiet?
This is one of the most relatable parts of the discussion. Many boys become noticeably more private and less verbal during puberty. Even boys who were once easy talkers may retreat. They may answer in one word. They may spend more time behind closed doors. They may seem harder to reach.
The instinct is often to interpret that as rejection. But Dr. Natterson’s point was that quiet does not mean disconnected. Boys still want support, conversation, and reassurance. They just may not ask for it in a straightforward way.
Sometimes showing up means sitting on the other side of the door and making it clear we are available. Not intruding. Not forcing. Just staying present.
Should we allow more privacy during puberty?
Yes, within reason. Wanting privacy is a normal developmental milestone. A closed door is not automatically a red flag. Often it simply means a child is trying to establish space and autonomy.
That does not mean total withdrawal is healthy. The balance is to respect privacy while continuing to invite connection. We can knock. We can check in. We can make ourselves available. We do not need to treat every closed door like a threat.

When Puberty Starts Earlier
Is earlier puberty a problem?
It can be, especially because the starting line has moved more than the finish line. Physical development is beginning years earlier, while the average age of the first period has shifted less dramatically. That means puberty is stretching out over a longer period of time.
Dr. Natterson described it almost like taffy. The whole process is getting pulled longer.
That can create real challenges. Kids may look older before they are emotionally ready. They may experience body changes while still very much being little kids in judgment, self-concept, and coping. Families may also underestimate what is happening because they are expecting puberty on an older timeline.
Why is puberty starting earlier?
There is still more to learn, but one of the strongest themes is chronic stress. Social factors appear to matter a great deal. We often talk about differences by race, but a more useful frame may be environment and resources. Stress, poor sleep, food insecurity, limited healthcare access, unstable housing, and other chronic burdens seem deeply relevant.
That is a hard truth because it reminds us puberty is not just biology. It is also lived context.
Height, Growth, and Weight Concerns
How does puberty affect height?
For girls, earlier regular periods can mean an earlier end to growth because estrogen helps close the growth plates in bone. Girls tend to grow about two to three inches a year for a few years. Boys often grow two to four inches a year for longer, which is one reason they eventually overtake girls in height.
The simplest prediction tool doctors often use is the mid-parental height estimate, based on the biological parents’ heights. But it is only an estimate. Actual growth also depends on overall health, nutrition, chronic illness, medications, lung health, gut health, and a long list of other factors.
When should short stature be evaluated?
The real question is not whether a child is shorter than someone else. It is whether their growth pattern is consistent with their own chart and family history. A child who has always been on the shorter side but follows the same curve is very different from a child who drops off their growth curve.
If growth slows unexpectedly, or puberty seems delayed, that is worth discussing with a pediatrician. And if the concern turns into a conversation about growth hormone, that belongs with a pediatric endocrinologist, not a casual decision.
One thing Dr. Natterson said very directly is that society prizes height in a way that is often irrational and unfair, especially for boys. That pressure can distort decision-making. Medical treatment should be driven by health, not by panic over social preferences.
What about boys with breast growth or extra weight?
This comes up far more often than many families realize. A large percentage of boys will have some degree of breast budding during puberty. Sometimes it is actual glandular tissue. Sometimes it is extra fat sitting in the chest area. Sometimes it is both.
Extra body fat can increase the conversion of hormone relatives into estrogen-like compounds, which may contribute to this breast growth and can also affect the balance between estrogen and testosterone. That hormonal balance may even delay puberty in boys carrying a significant amount of extra weight.
But the bigger issue is not blaming families or children. It is recognizing the broader food environment kids are growing up in. Cheap, ultra-processed, calorie-dense food is everywhere. Quality nutrition is harder to access than it should be. That is a public health problem, not a moral failure.
Mental Health, Hormones, and What Is Normal
How can we tell the difference between hormones and a mental health problem?
Sometimes we cannot, at least not immediately. There is real overlap between puberty-related mood swings and emerging mental health issues. That is why the best early tool is not a checklist. It is trusted adult intuition.
If something feels off, even if we cannot fully explain it, it is worth reaching out to a pediatrician, family doctor, therapist, or psychiatrist. We know the kids in our lives. We know their baseline. If a change feels concerning, we should not ignore that signal.
That applies to all genders. Yes, testosterone can contribute to anger and intensity. But not every angry moment is pathology. Sometimes the feeling itself is valid. What kids need to learn is how to carry and express that feeling safely.
Screens, Phones, and Social Media
When should kids get a phone?
The basic answer was: as late as we reasonably can. Delay helps. The older and more mature the brain, the better. But the conversation is more nuanced than simply declaring phones bad.
Devices are tools. Sometimes they are genuinely helpful. Sometimes they are social lifelines. For some kids, especially those who feel isolated in their offline world, online communities can be protective and affirming.
So the more useful goal is not fantasy-level elimination. It is intentional introduction and ongoing guidance.

Do we have to go straight to a smartphone?
No. That is one of the smartest practical takeaways. It does not have to be all or nothing. A child can start with a basic phone or a limited-function device. Social media can also wait even if texting does not. We can stagger access instead of opening every door at once.
How do we manage screen time without turning it into war?
Curiosity helps more than surveillance. One of Dr. Natterson’s favorite strategies was asking kids to show their screen time and walk through what they actually do on apps. Not in a gotcha way. In a genuinely interested way.
That approach does two things. First, it tells kids we care about their digital lives because their digital lives are part of their real lives. Second, it helps them become more aware of their own habits.
Older teens may even be able to set their own limits. That does not make them incapable of bypassing those limits, but self-chosen boundaries can be more meaningful than imposed ones.
And yes, boredom matters. Kids need unstructured time. Creativity often starts where stimulation ends. If screens fill every empty second, there is less room for imagination, wandering, invention, or rest. We also know device habits can disrupt sleep, especially at night, which is why practical strategies like those in this sleep and screen guide can be helpful for families trying to create healthier rhythms.
Gender Identity and Sexual Orientation
Why are more kids talking about being trans, bi, or fluid?
Part of the answer is that there is simply more language now. More openness. More room to try on identity without immediate silence or suppression. That does not mean every declaration signals a fixed lifelong path. It means kids have more vocabulary for inner experience and more permission to explore it out loud.
It is also important to separate gender identity from sexual orientation. They are not the same thing. One is about how someone understands themselves. The other is about who they are drawn to.
How should we respond if a child wants to change pronouns or explores gender?
The advice was refreshingly calm: listen, stay curious, and do not turn it into a crisis. Some kids are deeply certain and suffering intensely in a body that feels wrong to them. Those kids deserve thoughtful, specialized care. Other kids are exploring language, community, or expression. That also deserves respect, not panic.
The key is not to make the adult reaction the center of the story. We do not need to leap to extremes. We need to be present, informed, and responsive to the actual child in front of us.
What if parents are the ones struggling most?
That happens often. Sometimes the child is less distressed than the adults around them. This is a good moment to remember that support does not mean controlling the outcome. It means making room for honesty and reducing shame.
Porn and Sex Education
What should we know about porn exposure today?
This may be one of the most urgent modern parenting issues because exposure happens early and often by accident as well as by choice. Free pornography is widely accessible, highly aggressive in grabbing attention, and often becomes a child’s first model of sex long before any real relationship experience exists.
That is a problem because porn can teach distorted lessons about bodies, consent, pleasure, aggression, intimacy, and gender dynamics. Many kids absorb those messages before they have any framework for questioning them.

Why are kids especially vulnerable to it?
Because the adolescent brain is still under construction. The emotional and reward-centered systems mature earlier than the part of the brain responsible for long-range judgment and consequence weighing. In other words, the part that says this feels intense and compelling is highly active, while the part that says maybe this is harmful or unrealistic is still slow.
That mismatch creates a perfect storm in a world where explicit content is easy to reach.
How should we talk about porn?
Often, directly, and without moral panic. Kids need to hear that porn is not sex education. They need to hear that real intimacy includes mutual respect, care, communication, and pleasure for both people. They need to hear that much of what they may encounter online is exaggerated, performative, or violent in ways that do not represent healthy sex.
And they need those conversations more than once. One talk will not do it.
Stress, Pressure, and the Culture We Have Built
How much is stress affecting kids?
Enormously. Chronic stress is not just emotional. It is biological. The adrenal glands release cortisol, and when cortisol remains high over time, it affects the entire body. It can impact the immune system, the cardiovascular system, muscles, sleep, and overall regulation. It also appears linked to earlier puberty.
That means the pressure cooker many kids live in is not just making them anxious. It may be reshaping development itself.
What kinds of stress are we talking about?
Everything from college pressure and packed schedules to family instability, financial stress, violence, addiction, war, climate anxiety, political conflict, and social comparison. Some kids carry elite overachievement stress. Others carry survival stress. Many carry both.
That is why the answer cannot only be personal. Some of this is structural. But in our own homes, we can still make meaningful changes.
What should we do differently as parents?
Back off more than many of us think. Stop trying to turn children into tiny professionals. Stop over-scheduling every hour. Stop confusing resume-building with healthy development. Put the phone down. Be present. Laugh. Notice them. Let them be kids.
There was also a powerful reminder that kids growing up with adversity need communities around them, not judgment. Families under chronic strain need support, resources, and compassion. And all of us can benefit from more awareness of how our own distraction affects the emotional climate at home. This is one reason conversations around distracted parenting matter so much.

The Best Ways to Talk About Puberty
If we had to follow five guiding principles, what would they be?
Dr. Natterson ended with five clear takeaways that are worth keeping close:
- Leave judgment at the door. Our feelings about bodies, puberty, sex, mood, identity, and timing should not run the conversation.
- Remember it is their puberty, not ours. Our old stories are not always useful unless they help create warmth or humor.
- Engage often. Ask real questions, especially open-ended ones that invite more than yes or no answers.
- Respect the need for space. If they close the door for a while, do not assume the relationship is over. Stay available.
- Find our own trusted adults. Parenting through puberty is easier when we have people we can ask, lean on, and learn from.
That last point may be the most underrated. Kids need trusted adults, yes. But adults do too. We need friends, siblings, clinicians, and wise people we can call when we are unsure. Puberty parenting is not meant to be done in isolation.
FAQs
What is the first sign of puberty?
Often it is emotional or behavioral rather than physical. Increased privacy, mood shifts, irritability, and bigger reactions may show up before obvious body changes.
Does puberty start with a girl’s first period?
No. A first period is usually a middle marker, not the beginning. Puberty often starts earlier with breast budding and hormone-driven emotional changes.
At what age do girls usually start puberty now?
Many girls now begin puberty between ages eight and nine, though there is still a normal range around that average.
At what age do boys usually start puberty now?
Many boys begin between ages nine and ten. Because the first physical signs are less visible, puberty in boys is often recognized later than it actually starts.
Are acne, pubic hair, and body odor always signs of puberty?
Not necessarily. Those changes are often related to adrenarche, which can overlap with puberty but is driven by the adrenal glands and may happen on a different timeline.
Should we worry if one breast starts developing before the other?
Usually no. Uneven breast budding is common and often normal during early puberty.
When should painful periods be evaluated?
If a teen is missing school, curled up in pain, vomiting, or unable to function during periods, that deserves medical evaluation. Severe pain should not be dismissed as normal.
How should we handle social media and phones?
Delay access as long as reasonably possible, consider starting with a basic phone, and stay curious about how devices are being used. Ongoing conversation works better than one-time rules alone.
How often should we talk to kids about porn and sex?
More than once. Repetition matters. Kids need regular reminders that porn is not sex education and that healthy intimacy involves respect, consent, care, and communication.
What is the biggest parenting takeaway from all of this?
Stay connected without becoming controlling. Respect privacy, reduce judgment, make space for ongoing conversation, and remember that our job is to support development, not manage every feeling or outcome.
Puberty is not neat, and it is definitely not brief anymore. But it does not have to be terrifying. When we understand what is changing and why, we are much less likely to confuse normal development with defiance, silence with rejection, or curiosity with crisis.
What kids need most is not a flawless talk. They need us to stay available, stay calm, and keep showing up.
