Why Won't My Older Child Go to Sleep? Bedtime Habits for Ages 9–13

From late-night screen time to racing thoughts, understand why bedtime changes as children grow — and how to help them build healthier sleep habits.

“Just five more minutes.”

It's 9:30 pm. You've already asked your child to put their phone away, turn off the light and go to sleep.

But they're not tired. They have something important to finish. And apparently, everyone else is allowed to stay up later.

Sound familiar?

As children move towards adolescence, bedtime can become less about needing another story and more about negotiating independence.

Why do sleep habits change as children get older?

Between ages nine and thirteen, children experience significant changes in their thinking, emotions and social awareness.

Friendships become increasingly important. School demands grow. They become more aware of how others see them and may spend more time reflecting on their day.

As puberty begins, biological changes can also shift the body's natural sleep timing, making some children feel sleepy later in the evening.

This doesn't happen at exactly the same age for everyone, but it helps explain why a bedtime that worked at eight might become more difficult at twelve.

Children aged 9–12 generally need 9–12 hours of sleep each night. At 13, the usual recommendation is 8–10 hours.

The challenge is that their growing independence can arrive before their ability to consistently manage bedtime decisions.

Why screens make switching off harder

For older children, screens are often more than entertainment.

They're where friendships happen, games continue and social conversations unfold.

So when you ask your child to put their device away, you may be interrupting something that feels genuinely important to them.

There are also biological reasons to limit screens before bed.

Bright light can interfere with the body's preparation for sleep. Exciting games, social media and emotionally engaging content can keep the mind alert long after the device is switched off.

Where possible, keep phones and tablets charging outside the bedroom overnight.

But rather than simply introducing another rule, explain why you're doing it.

You might say:

“We're going to try keeping phones downstairs at night because your brain needs time to wind down. Let's work out a routine that feels manageable.”

Involving your child in the plan can help them feel respected without giving up the boundary.

“I'm not tired!” — what might be happening beneath that response?

Sometimes your child genuinely doesn't feel sleepy yet.

Other times, bedtime may be the first quiet moment they've had to think about everything that's happened during the day.

Perhaps they're replaying an awkward conversation with a friend.

Maybe they're worrying about tomorrow's test.

Or perhaps they simply don't want to miss out on what everyone else is doing online.

The behaviour might look like defiance, but the underlying experience could be very different.

Before deciding how to respond, try asking:

“Is it that you're not feeling sleepy, or is there something keeping your mind busy?”

That question opens up a different conversation.

When thoughts keep children awake

One of the most useful CBT principles is understanding how thoughts, feelings and behaviour influence one another.

Imagine your eleven-year-old has a maths test tomorrow.

They think, “I'm going to get everything wrong.”

That thought creates anxiety. They lie awake rehearsing what might happen, which makes it harder to fall asleep.

The following evening, they may begin worrying about bedtime itself.

Now the problem isn't just the test. It's also the thought, “I won't be able to sleep again.”

Rather than immediately reassuring them that everything will be fine, help them examine what's going through their mind.

You could ask:

“What are you most worried might happen?”

And later:

“What's something you could tell yourself that's a little more balanced?”

Perhaps they arrive at:

“I might find some questions difficult, but I've prepared, and I can try my best.”

The aim isn't to force positive thinking. It's to help children recognise when their thoughts are making a situation feel more threatening than it may be.

These conversations are often easier during the day, rather than when everyone is tired.

Build a routine that respects their growing independence

Older children still benefit from predictable sleep routines, but they may respond better when they're involved in creating them.

Start with a consistent wake-up time and work backwards to establish a realistic bedtime.

Then agree on a simple wind-down routine.

For example:

• 60 minutes before bed: Devices away and charging outside the bedroom.
• 30 minutes before bed: Shower, prepare school things and finish any remaining tasks.
• 15–20 minutes before bed: Read, listen to something calming or spend a few minutes talking.
• Bedtime: Lights out, with a quiet, comfortable sleeping environment.

Consistency matters, including at weekends, although some flexibility is reasonable.

And remember that a routine should support sleep, not become another source of conflict.

What if your older child still wants you nearby?

We often associate needing reassurance at bedtime with younger children.

But older children can still experience night-time anxiety, separation worries or difficulty settling alone.

The need for co-regulation doesn't disappear at a particular birthday. It gradually changes as children develop greater independence.

An eleven-year-old might not want you sitting beside their bed, but they may still appreciate ten minutes of conversation before saying goodnight.

A child who struggles to settle might benefit from knowing you'll check on them briefly.

The important distinction is between offering reassurance and unintentionally reinforcing the belief that they cannot manage without it.

You can provide comfort while gradually encouraging confidence.

For example:

“I know bedtime feels difficult sometimes. Let's think about what helps you feel calmer, so you can practise doing more of that yourself.”

Try this: a five-minute worry check-in

If your child regularly lies awake worrying, introduce a short check-in earlier in the evening.

Ask them to identify one thing that's on their mind.

Then explore three questions:

1. What's the thought that's bothering you?
2. What evidence supports it, and is there another way to look at it?
3. Is there something useful we can do about it tomorrow?

If the worry needs action, agree on a small next step.

If it doesn't, encourage your child to recognise that they don't need to solve every problem at bedtime.

This isn't about dismissing worries. It's about helping children learn when to explore a thought, when to make a plan and when to let it wait.

With practice, these skills can become part of how they manage anxiety beyond bedtime.

Why one good night isn't the goal

Changing sleep habits can take time.

A new routine might work well on Monday and fall apart by Thursday.

That doesn't necessarily mean the approach has failed.

Children are learning skills that require repetition: managing transitions, tolerating uncomfortable feelings, recognising unhelpful thoughts and making choices that support their wellbeing.

If sleep problems persist, significantly affect daytime functioning, or involve loud snoring or breathing difficulties, seek advice from a healthcare professional.

How Thymos can help

At Thymos, we recognise that the same behaviour can have different explanations depending on a child's age, development and circumstances.

A younger child refusing bedtime may need help managing separation. An older child might be struggling with racing thoughts, social pressures or increasing independence.

Thymos Chat uses guided, CBT-informed exploration to help you understand what may be happening beneath your child's behaviour and consider a more appropriate response.

And through the Learning Hub, you can build practical CBT-informed skills — understanding thoughts, feelings, avoidance, emotional regulation and gradual confidence-building.

These aren't strategies to use once and forget.

They're skills to practise in everyday moments, helping you and your child respond differently over time.

Because understanding behaviour is about more than managing tonight.

It's about helping children develop the skills they'll carry into adolescence and beyond.
