A new school year brings new routines, teachers, sports, homework and plenty of time sitting, reading and looking at screens.

For children, these everyday demands come at a time when their bodies are still developing. Their spines are growing, body proportions are changing, postural habits are being established, and their eyes and nervous systems are working hard to support reading, learning and movement.

At Pure Health Chiropractic, we believe back-to-school preparation should go beyond stationery and school shoes. It is also a great time to check in on how your child is moving, sitting, seeing and coping with the demands of their day.

Your Child’s Spine Is Still Growing

The spine doesn’t simply “stop developing” at a particular age. Children grow at different rates, with significant changes occurring during puberty and adolescence.

The major adolescent growth spurt generally occurs earlier in girls than boys. On average, girls reach their peak height growth around 11–13 years, while boys tend to reach it around 13–15 years. The timing can vary considerably from child to child.

During these periods of rapid growth, body proportions and coordination can change quickly. A child who seemed comfortable on their bike, in their school chair or carrying their backpack last year may suddenly need things adjusted.

This is one reason the school years are an important time to encourage healthy movement habits and regular physical activity, rather than focusing on maintaining one “perfect” posture.

Posture Is About More Than Sitting Up Straight

It’s tempting to tell a child to “sit up straight,” but good posture isn’t about holding one rigid position all day.

Children need to be able to move between positions, maintain comfortable alignment and develop the strength, coordination and mobility to handle everyday activities.

The bigger issue is often sustained posture (staying in the same position) for too long.

Think about how your child spends their day:

-Sitting at a school desk
-Reading and writing
-Using a tablet or computer
-Playing video games
-Looking at a phone
-Travelling in the car
-Doing homework

Encourage your child to change position and move regularly. A short walk, stretch or change of activity can break up long periods of sitting.

At home, make sure their study area allows their feet to be supported and their books or screen to be at a comfortable height. Most importantly, don’t expect a child to sit perfectly still for hours. Movement is part of healthy posture.

Check the School Backpack

A school bag can become surprisingly heavy, particularly as children carry books, sports equipment, lunch and other items throughout the day.

Check that:

-Both shoulder straps are being used.
-The straps are adjusted so the backpack sits comfortably against the back.
-Heavier items are kept closer to the child’s back.
-Unnecessary items aren’t being carried around all day.
-The bag isn’t causing discomfort or forcing your child to lean, twist or hike one shoulder.

Remember that children grow quickly. A backpack that fitted well last year may not fit as well after a growth spurt, so check the fit regularly.

Has Their Bike Grown With Them?

Cycling is a fantastic way for children to stay active and, for many, is an important part of getting to school.

But just like a backpack, a bicycle that fitted well last year may need adjusting after a growth spurt.

Check the:

-Saddle height
-Handlebar position
-Reach to the handlebars
-Helmet fit
-Overall comfort while riding

If your child suddenly looks cramped, is stretching excessively to reach the handlebars or regularly complains of discomfort after cycling, consider having the bike professionally checked and adjusted.

Encourage Sport and Movement

While we spend a lot of time talking about sitting and posture, one of the best things parents can do for a growing child is encourage them to move.

Sport and physical activity help children develop strength, balance, coordination, agility and body awareness. They also provide a valuable break from the sustained sitting that comes with school and screen time.

Football, swimming, gymnastics, dance, martial arts, tennis, athletics, cycling or simply playing outside with friends can all be great options. It doesn’t have to be competitive. The most important thing is finding activities your child enjoys and wants to participate in.

During growth spurts, children may temporarily feel less coordinated as their bodies change. This doesn’t mean they need to stop being active. Encourage them to build activity gradually, listen to their bodies and allow appropriate recovery.

If your child develops persistent pain, recurring discomfort or a noticeable change in how they move, don’t simply assume it’s “growing pains.” Consider discussing it with an appropriate healthcare professional.

Could Their Eyes Be Part of the Picture?

Vision can also influence how a child sits, moves and performs at school.
Reading, writing and screen-based learning require the eyes to focus and coordinate for sustained periods. Sometimes what looks like a posture, concentration or learning issue may have a visual component.

A child who is struggling to see comfortably may move closer to a book or screen, tilt their head, lean forward or adopt an unusual position to make the task easier.

Keep an eye out for:

-Frequent eye rubbing or blinking
-Squinting
-Headaches after reading or screen use
-Tired or sore eyes
-Closing or covering one eye
-Losing their place while reading
-Skipping words or lines
-Difficulty copying from the board
-Holding books unusually close
-Avoiding reading
-Difficulty concentrating during visually demanding tasks
-Tilting or turning their head while reading

These signs don’t necessarily mean your child has a vision problem, but they’re worth paying attention to.

Have a Conversation With Your Child

Children don’t always tell parents when something feels uncomfortable, especially if they assume it’s normal.

Before the school year gets too busy, ask simple questions:

“Does anything feel uncomfortable when you’re sitting at school?”
“Do your eyes get tired when you’re reading?”
“Do you get headaches after school or homework?”
“Can you see the board comfortably?”
“Does your backpack feel heavy or uncomfortable?”
“Do you feel comfortable when you’re cycling or playing sport?”

Sometimes simply asking the question can reveal something your child hasn’t mentioned before.

Regular eye examinations are an important part of children’s health and can identify vision problems that may otherwise go unnoticed. If your child is experiencing headaches, eye fatigue, difficulty reading, squinting, trouble seeing the board, eye strain or changes in their visual behaviour, an optometrist can assess their vision and eye health.

At Pure Health Chiropractic, we also assess aspects of your child’s posture, movement, coordination, balance and visual function. As chiropractors with additional training in functional neurology, we look at eye movements, visual tracking, how the eyes work together and how visual information integrates with movement and the nervous system. This can be particularly relevant for children experiencing headaches, eye strain, difficulty focusing or visual fatigue, as well as those with persistent postural or movement concerns, changes in coordination, balance difficulties or unusual movement patterns. If you notice persistent changes in your child’s reading, visual comfort, posture or ability to sustain visually demanding tasks, it may be worth having them assessed by an appropriate healthcare professional.

A Healthy Start to the School Year

Back-to-school is a great opportunity to reset your child’s daily habits.

Check the backpack. Adjust the bike. Create a comfortable study space. Encourage regular movement and sport. Pay attention to screen and reading habits. And listen when your child tells you something doesn’t feel right.

Children go through enormous physical changes during their school years. Their bodies are growing, their proportions are changing, and they’re learning how to move and use their bodies in new ways.

The goal isn’t perfect posture. It’s helping children develop healthy habits, stay active and feel comfortable as they grow.

If you’re concerned about your child’s posture, movement, coordination or visual-related behaviours, Pure Health Chiropractic can help you understand what you’re seeing and whether an assessment may be appropriate.

Give your child’s growing body the support it needs for a healthy start to the school year.
