9-10 Years

Nine, our last single-digit year.

No longer little, not quite a teenager, welcome to the beginning of pre-adolescence. They have a real identity now: things they love, things they’re good at, friends who matter, opinions they argue. And they are starting to be private in ways they weren’t before. You can catch glimpses of an inner life as this new stage of development begins.

Your visit at a glance

What we’ll do

• Measure weight, height, and BMI
• Physical exam
• Screenings and a conversation about school, friendships, body, mental health, and screens.

Your child is old enough to lead parts of their own care now, so we’ll help them practice.

Vaccines today

• Catch-up doses if needed

Screenings we’ll review

• Vision and hearing
• Development, behavior, and mental health
• Cholesterol screening if indicated

Bring with you: Your top 3 questions. Any concerns about mental health, body changes, friendships, school, or devices. If your child wants to discuss something privately, tell us ahead and we can raise it while you step out.

🌟 HPV vaccine: what to know before the 11-year visit

Your child is 9 or 10, and here we are bringing up a vaccine you probably think of as a teen thing. We know it can feel early. Here is why it comes up now, a year or two before the shot.

The HPV vaccine is one of the strongest cancer-prevention tools in pediatrics. HPV is so common that about 80% of sexually active people encounter it at some point, and the cancers it can cause are largely preventable. The vaccine helps prevent six HPV-related cancers (cervical, vaginal, vulvar, penile, anal, and oropharyngeal) and most genital warts. We give the first dose at our 11-year well-visit, with a second dose 6 to 12 months later to complete the series.

This visit is the window to learn the basics and bring your questions, so you feel ready on shot day.

Why the timing matters: the vaccine works best given before any exposure, and the immune response is strongest at ages 9 through 12. Started before 15, the series is 2 doses instead of 3. The CDC and AAP now allow starting as early as 9 for this reason, which puts our 11-year first dose well inside the most-effective window.

Common questions:

• Is it safe? Studied in millions of children worldwide for nearly 20 years, with an excellent safety profile. Most common side effects: a sore arm and mild fever, like any vaccine.
• Does it encourage sexual activity? This has been studied extensively. The vaccine has not been linked to earlier or more sexual activity. What it does is protect against a virus that most sexually active people will encounter at some point.
• What if my child isn’t sexually active anytime soon? Even better. There is no benefit to waiting.

Bring your questions to this visit. We’re happy to talk through the evidence together. More from CDC on HPV vaccine for parents and AAP on the HPV vaccine.

Puberty at 9-10: where most kids are

For many kids, the first sign is breast budding, often around 9-10 (range 8-13). Pubic hair, body odor, and a growth spurt follow over the next year or two. A first period usually arrives 2-3 years after breast budding starts, so for a child who starts at 9-10, that often means around 11-12.

For others, the first sign is testicular enlargement, often around 10-12 (range 9-14). Pubic hair, voice change, and a growth spurt follow.

The whole process takes 3 to 5 years, and mood changes and self-consciousness come with it. Make space for both the body changes and the emotional weather. Revisit Girlology, Guy Stuff, and the other puberty resources we shared at the 7-8 year visit. This is an ongoing conversation, not a single talk. More from Girlology and AAP HealthyChildren on puberty.

Mental health at 9-10: what’s normal and what isn’t

Anxiety and depression rates begin to climb in this age range, especially for girls. About 8 to 10% of kids this age have an anxiety disorder at any given time. We screen for mental health at this visit, so if anything has been on your mind, today is the day.

Signs of concern:

• Persistent low mood or irritability for 2+ weeks.
• Loss of interest in things they used to enjoy.
• Sleep or appetite changes.
• Withdrawal from friends or family.
• Declining school performance.
• Anger that’s out of character, or self-critical talk.
• Any statements about not wanting to be here.

Childhood and tween mental health responds very well to early intervention, often with brief, targeted therapy. More fromChild Mind Institute on signs of anxiety in kids and teens and AACAP family resources.

Body image and self-esteem at 9-10

Body image concerns emerge now, especially in girls but increasingly in boys too. Social media accelerates all of it.

Common patterns: comparing themselves to peers, more mirror time, wanting to change their appearance, commenting on weight (theirs or others’), avoiding certain clothing, dropping activities they used to enjoy.

What helps:

• Keep home a body-positive space: no negative talk about your own body, no diet talk, no labeling foods “good” or “bad.”
• Praise things other than appearance.
• Model self-acceptance.
• Limit social media exposure.
• Watch for early eating-disorder signs: food rituals, secretive eating, dramatic weight changes, exercise that feels compulsive. Caught early, they’re far more treatable. If something concerns you, mention it today.

More from Common Sense Media on body image and media and Child Mind Institute on body image.

Lipid (cholesterol) screening today

The AAP recommends universal lipid screening once between ages 9 and 11, and this is the visit for most kids. It’s a simple blood draw (non-fasting is fine for the first screen).

Why now: many kids with elevated cholesterol have a family history they don’t know about, and lifestyle changes started in childhood work far better than those started in adulthood. If the screen is abnormal, we’ll do a fasting follow-up. Most kids benefit from dietary changes and more physical activity. Some need more. More from the American Heart Association on cholesterol.

Sleep at 9-10

Most 9-10 year olds need 9 to 12 hours. School-year bedtimes usually settle between 8:30 and 9:30pm.

Common disrupters: screens close to bedtime, anxiety, academic pressure, social worries, growing pains during spurts.

What helps:

• A consistent routine.
• Screens and phones out of the bedroom (this is the age to start enforcing, even if you allowed it before).
• A real wind-down before bed.

If sleep has gotten worse with no obvious cause, mention it. More from AAP on healthy sleep habits and hours by age.

💗 Family / Community, for you and your ʻohana

🌟 Family screen time and the smartphone decision

The most consequential parenting decisions of the tween years are about devices:

• When does your child get their first smartphone?
• When do they get social media accounts?
• Where can devices live in the house?
• How much time per day?

On smartphones: the research increasingly shows that waiting until at least 8th grade (age 13-14) is protective. Anxiety, depression, sleep disruption, body image issues, exposure to age-inappropriate content, and social comparison all worsen with smartphone access before 13. A growing parent movement (Wait Until 8th, the Anxious Generation work by Jonathan Haidt) backs the same line.

On social media: most platforms set a minimum age of 13. They aren’t built for younger kids, and earlier exposure to algorithmic content is linked to worse mental health, especially for girls.

Family rules that hold, whatever you decide:

• No phones or devices in bedrooms, especially overnight. This single rule has the highest impact.
• No phones during meals (parents included).
• No phones in the hour before bed.
• Parents have access to all accounts and passwords.
• Talk about what they see, don’t just monitor. If something bothers them, they can tell you without getting in trouble.

Alternatives at this age: kid watches (GPS plus calling, no internet), basic phones for logistics (calls and texts only), shared family devices used in shared spaces.

You build this as a family policy, together, over years. More from Common Sense Media and the AAP Family Media Plan.

Friendships, cliques, and peer influence

Friendship dynamics intensify, with best friends, falling outs, cliques, exclusion, sometimes meanness. Peer influence grows. Some of this is healthy identity formation, some is worth watching if values start shifting in ways that concern you.

What helps:

• Know your child’s friends and their parents
• Make your home a place friends want to come
• Watch for sudden friend-group changes (sometimes a sign of bullying)
• Listen more than you advise, and coach toward their own values instead of badmouthing their friends

More from Child Mind Institute on social challenges and Dr. Lisa Damour.

Consent and bodily autonomy

The body conversations from earlier years get an update. At 9-10, your child should understand:

• Their body is their own. They can say no to hugs, kisses, and tickling, even from family, and family should respect that. The hard version is when grandma demands a hug. Your job is to back your kid.
• Other people’s bodies belong to them too. Consent applies to how they treat friends and siblings.
• Sexual content (online, in media, anywhere) is for adults. If they see it, they can tell you or another safe grown-up without being in trouble.
• Bodies in pictures online aren’t real bodies. Filters, editing, posing, and lighting distort everything.
• A trusted adult is someone they could tell anything to. Make the list explicit: you, plus one or two others (a grandparent, an aunty or uncle, a teacher, a coach).

This is a series of small moments over years, not one talk.

Reading and academics

By 9-10, academic differences become more visible, and learning differences (dyslexia, dysgraphia, ADHD) often surface as demands rise.

Worth flagging: trouble keeping up with grade-level reading, slow writing or letter reversals beyond what’s developmental, focus or organization struggles, homework that takes much longer than expected, declining grades, growing reluctance to go to school. We can refer for a learning evaluation, and the school can sometimes do this through 504 or IEP processes. Earlier identification helps more than waiting. More from Child Mind Institute on learning differences.

Your wellbeing is still part of every visit

Parent wellbeing at 9-10: bracing for adolescence. The pre-teen shift begins. Watching their body and emotions change can bring some anticipatory grief for the child they were. Many parents revisit their own adolescence, sometimes painfully.

Signs worth attention: Family-of-origin material resurfacing as you anticipate parenting a teen. Anxiety about the teen years that feels disproportionate. Your own adolescence feeling vivid again. Partnership conflict over how to parent the coming years.

What helps: Therapy, especially if family-of-origin issues are surfacing. Read about adolescence before it arrives (Lisa Damour, Cara Natterson, Jonathan Haidt). Process your own teen years with a therapist or trusted friend. Align with your partner now. Build your support system before you need it. Lindsay Gibson’s Adult Children of Emotionally Immature Parents is one of the most useful books for parents entering adolescence with their own family-of-origin material still active.

Local Oʻahu resources 🌺

🌺 Sports and physical activity for tweens

Sports get more serious for some kids, and specialization conversations come up. Hawaiʻi has strong programs in soccer, baseball, basketball, swimming, surfing, volleyball, paddling, water polo, martial arts, dance, and hula.

The pediatric sports medicine consensus recommends against single-sport specialization before age 14: overuse injury rates are high (especially young pitchers, swimmers, gymnasts), burnout is common, and most successful college and pro athletes played multiple sports as tweens. Let your child sample widely, take time off between seasons, and be tired but not exhausted.

🌺 Hawaiʻi mental health resources for tweens and families

Concerns rise at this age, and Hawaiʻi has resources, though access varies by area:

• 988 Suicide & Crisis Lifeline: 24/7 national crisis line, also serves Hawaiʻi.
• Hawaiʻi CARES line: 808-832-3100, 24/7 mental health support and crisis line.
• Hawaii Department of Health CAMHD: services for children with significant mental health needs, often through school referral.
• Hawaii Psychological Association: find a licensed psychologist who works with tweens.
• Telehealth: many tween-focused therapy services are now available remotely, expanding access on neighbor islands and underserved areas.
• School counselors: every Hawaiʻi public school has counseling staff for mild-to-moderate concerns and referrals.
• Not sure where to start? Call us. We can help triage and refer.

If your child is in crisis (active suicidal thoughts, self-harm, severe distress), go to the nearest ED or call 988.

True at every age

Some things never stop mattering, no matter the age on this page:

• Dental care: cleanings every 6 months.
• Water safety: a year-round priority in Hawaiʻi, at every age.
• Sun protection: every day, even when it’s overcast.

🚨 When to call us

What’s ahead before your 11-14 year visit

The next visit covers ages 11 through 14, a wide developmental span. A lot happens. The big things to expect:

Puberty progresses for most kids. Whether your child started earlier or starts during this stretch, the changes continue and the whole arc takes years, not weeks.

HPV vaccine starts at the 11-year visit. First dose at 11, second 6 to 12 months later. We’ll cover it in detail then.

Meningococcal and Tdap arrive. At the 11-12 visit, we typically give MenACWY and the Tdap booster.

Mental health risk rises. Anxiety and depression rates climb most from 11 through 14. We keep this on our radar together.

The smartphone and social media decision comes (if it hasn’t already). Keep building toward the choice that fits your family.

Friendships keep evolving. Best-friend designations shift. Some kids find their people in middle school, some struggle. Coaching matters more than ever.

Independence grows. By 14, many kids manage their own time, get themselves to and from school, and babysit younger siblings. Build trust gradually.

Around 12, we also start some private, confidential time with your adolescent, giving them a safe space to ask us anything and practice managing their own care.

Until then, hold the line on the parts that matter. These next few years are formative in ways that get clearer over the next decade.
