Your 11-year-old: development, behaviour, sleep, play and what's normal

If your 11 year old has gone from cheerful chatter to sighs, slammed doors and long showers, you are not alone. Eleven is often the year childhood turns towards the preteen years: bodies change, friends and group chats matter more, and many children start a new school in class six. Under the attitude, most 11-year-olds still need you close.

Children develop at different speeds, so read this as a guide, not a test. It covers what to expect from an 11 year old: development and puberty, moods and attitude, friends and crushes, the move to class six, sleep and phones, a 7-day plan and when to get help.

What can an 11 year old do? Development at eleven

Most 11 year old milestones are about thinking in new ways and handling more alone, just as the body starts to change. These are rough descriptions; ahead in one area and behind in another is usually fine.

For the year before, see your 10-year-old, and for the 9 to 12 years as a whole, preteens.

Puberty at 11: body changes, hygiene and what to say

Puberty often starts somewhere around 8 to 13 in girls and 9 to 14 in boys, so at 11 it is under way for many girls and beginning for many boys. Common changes now:

• Girls: developing breasts, a growth spurt, hair under the arms, a white discharge in the underwear and, for some, the first period. Many girls start their periods somewhere between about 10 and 15.
• Boys: the testicles and penis start to grow, then body hair; a breaking voice and the big growth spurt usually come later, and wet dreams often start from about 12 or 13.
• Both: stronger sweat and body smell, oily hair and skin, pimples, a big appetite and more tiredness.

Hygiene is the practical job of this year. A daily bath, clean clothes and underwear every day, a deodorant if your child wants one and gentle face washing help with smell and pimples, and with confidence. Say it kindly and privately; teasing about smell or pimples teaches children to hide.

11 year old behaviour: moods, attitude and arguing back

Many parents find 11 harder than 10. Hormones, tiredness, a growing need for independence and a brain that feels emotions strongly before it can manage them all arrive together. These are common, and usually nothing to fear:

• Eye-rolling, sighs, 'you don't understand' and a closed bedroom door.
• Arguing about everything, and pointing out every time you break your own rule.
• Sudden tears or anger over small things, often when tired or hungry.
• Forgetting homework, losing things and leaving tasks half done, as planning skills catch up with a busier life.
• Embarrassment about parents in public, alongside a wish for closeness at bedtime.

When your 11-year-old snaps or slams the door

1. 1Respond to the message, not the tone, the first time: 'Sounds like today was rough.'
2. 2If it turns rude, name the line calmly: 'You can be angry. You can't speak to me like that.'
3. 3Let the door stay shut for a while; a heated moment is the hardest time to talk.
4. 4Come back later with something easy, like a snack, and talk side by side rather than face to face.
5. 5Repair after a fight: 'I shouted, and I'm sorry' teaches more than any lecture.

Friends, crushes and group chats at 11

At 11, fitting in can feel like everything. Friend groups shift, group chats begin, and a hurtful message or being left out of a plan can spoil a whole week. First crushes are common, and so is teasing about them. Around the move to a new school, teasing can also tip into bullying.

• Listen to friendship troubles without rushing to fix them, then ask: 'What would you like to happen?'
• Treat a crush calmly: 'It's normal to like someone. You don't have to do anything about it.' Never mock it, and ask relatives not to tease.
• Agree group-chat rules: who can add your child, no sharing photos of other people, and leave any chat that turns mean.
• If teasing becomes daily, physical or moves online, treat it as bullying: believe your child and act the same day; bullying at school has the steps.

From class five to class six: a new school, coaching and a routine

For many Bangladeshi children, eleven means the end of class five or the start of class six. Class six often brings a new school, more subjects and teachers, more homework, a longer journey and, for many, more coaching. Many children feel lost or tired for the first weeks, and most settle in with time and support.

The most useful things to teach at 11 are practical: keeping a weekly planner, packing the bag the night before, asking a teacher when lost, and making one new friend at a time.

• Before adding coaching, count what's left of the day: 9–12 hours of sleep, an hour of active play, some free time and family time.
• Ask any tutor to praise effort and never to hit or shame your child.
• Expect more tiredness in the first term, and keep weekends a little lighter.
• If worry about tests grows into sleepless nights or stomach aches on exam mornings, keep exam-week evenings calm, protect sleep and let the class teacher know.

Sleep, screens and a first phone: what an 11-year-old needs

• Sleep: most 11-year-olds need 9–12 hours in 24 hours. As puberty starts, many feel sleepy later at night, so a steady bedtime and no screens in the last hour matter more.
• Screens: from 6 there's no fixed number of hours; keep limits that protect sleep, at least 60 minutes of active play, homework and family time, with devices out of the bedroom at night.
• Food: regular meals and snacks; growth spurts bring big appetites, so offer rice, dal, eggs, fish, vegetables and fruit rather than more chips and soft drinks.
• Active play: at least 60 minutes a day of moderate-to-vigorous activity. Good 11 year old activities: football, cricket, badminton, cycling in a safe lane, swimming, dance, martial arts or a sports club.

Should an 11-year-old have a smartphone?

Many children ask for a smartphone at 11, often when they start travelling to a new school or coaching. A basic phone for calls often covers the real need; what age a child should get a phone has the readiness signs. If you do choose a smartphone, agree the rules first:

• Most social apps set 13 as the minimum age; until then, no accounts of their own.
• Phones charge outside the bedroom at night and stay off the table at meals.
• Games only with age ratings you have checked, purchases turned off and no chat with strangers, at agreed times that leave room for sleep and homework.
• If anyone online asks for photos, secrets or a meeting, your child tells you, and won't be in trouble for telling.

In a Bangladeshi home: privacy, comments and growing up

Privacy in a shared room or a joint family

At 11, many children start wanting to bathe and change alone, keep a diary or close the door, even in a small flat or a full joint-family home. Privacy can be simple: a knock before entering, a drawer or box of their own, a few minutes alone after school. Ask grandparents, cousins and house help to knock too.

Comments about skin, weight and height

Relatives often comment on a changing body: 'You've gone dark', 'You're getting fat', 'Why is he so short?' At 11, these remarks can stick for years. Step in kindly: 'Let's not comment on her body; this age is hard enough.' At home, talk about what bodies can do, not how they look.

New expectations, without shame

Around puberty, many families start new expectations for sons and daughters: different clothes, separate sleeping places, new manners with guests. Families follow their own values here. Whatever yours are, explain them warmly, apply them fairly, and keep one message clear: 'Your body is growing up, and that's a good thing.'

A 7-day plan for a calmer week with your 11-year-old

Pick one change, note what happens each day, and compare after a week.

1. 1Day 1: Note the hardest moment of the day: the morning rush, after school, homework, coaching, phone time or bedtime.
2. 2Day 2: Set up a weekly planner together, and a fixed place for the school bag.
3. 3Day 3: Agree screen and phone rules, write them down, and charge devices outside the bedroom.
4. 4Day 4: Knock before entering your child's room, and notice whether the mood changes.
5. 5Day 5: Start a short, calm talk about body changes or hygiene, using a hook such as buying a new soap or deodorant.
6. 6Day 6: Ask about friends side by side, in a rickshaw or while cooking, and only listen.
7. 7Day 7: Compare with Day 1, keep what helped, and share it with everyone who looks after your child.

When to talk to a doctor or teacher about your 11-year-old

Most moods and body worries at 11 are part of growing up. Talk to your child's doctor, and the teacher where it fits, if:

As your child turns 12, your 12-year-old covers what often comes next. ParentMind helps you note moods, sleep, homework and phone time each day, so you can see patterns rather than single bad days; see how ParentMind works.
