Toddler Sleep Regression: Why It Happens and How to Reset the Routine

Written on the 23 September 2026

Just when you think you've finally got bedtime figured out, your toddler starts fighting it again. They may take much longer to settle, wake during the night, start getting up before sunrise, or decide the nap they once loved is no longer happening.

It's frustrating, especially when nothing obvious seems to have changed. The reassuring part is that a change in sleep doesn't automatically mean you've done something wrong, or that something is wrong with your child. Toddlers are growing, becoming more independent, and their daytime sleep needs are shifting — their nighttime sleep can change right along with them.

What is toddler sleep regression?

Parents often use "sleep regression" to describe a child who's been sleeping relatively well suddenly having more trouble settling, staying asleep, or following their usual routine. These shifts tend to show up alongside development, changing daytime sleep, illness, separation, or a change in routine. There's no fixed age it happens at, and not every toddler goes through a noticeable one.

What does it look like?

Sometimes the change is obvious. Other times it's just a subtle shift from what your child usually does. You might notice them:

• Taking much longer to settle at bedtime

• Suddenly fighting bedtime altogether

• Repeatedly getting out of bed

• Waking more often overnight

• Waking much earlier than usual

• Getting upset when you leave the room

• Resisting or refusing their usual nap

• Seeming tired or unsettled during the day

• Wanting more reassurance at bedtime than before

None of these tells you exactly why it's happening — they're clues to look at alongside the rest of their day.

What might be behind it?

There's rarely one tidy explanation. Toddler sleep is closely tied to what's happening developmentally, emotionally, and practically.

The goal isn't to land on a single explanation at all costs — sometimes a few small things are happening at once.
 

Why does sleep change around two and three?

There's no fixed regression that every child goes through at either age. But two and three are times when parents may notice changes, simply because so much else is happening developmentally.

Around two years

Two-year-olds are becoming much more aware of themselves and what they want. They can communicate more, make choices, and increasingly understand they can influence what happens around them — and that new independence often shows up at bedtime.

"Another story." "I don't want to go to bed." "One more cuddle." "I need a drink."

Sometimes bedtime just becomes another chance to practise having a say.

Daytime sleep may be shifting too. Some two-year-olds still need a solid nap; others are starting to need less. If a nap runs later or longer than they actually need, they may simply not feel ready for bed at the usual time.

Around three years

By three, language, imagination, and independence have all developed considerably. Children this age have more questions, bigger ideas, and new worries they can finally put into words. A child who previously went to bed happily may suddenly want another story, ask you to stay longer, or worry about something they've imagined.

Daytime sleep is often shifting here too — some children are moving away from naps altogether, others still need them, and there's no single timetable that fits everyone.

So if your three-year-old suddenly starts resisting bedtime, it doesn't necessarily mean you've got a new problem to solve. Something about their needs or their day may just have changed.

It's not always developmental

Sometimes the explanation is more ordinary. Has your child recently started childcare? Moved into a new room? Had a holiday? Been unwell? Welcomed a new sibling? Changed bedrooms? Started a different daily routine?

Even positive changes can temporarily unsettle a familiar pattern. A toddler may also want more reassurance after a day away from a parent or after something new happens in their world. If bedtime suddenly involves more cuddles or a request for you to stay, it doesn't mean you've created a bad habit — they may simply be looking for connection at the end of a busy day.

Could a changing nap be behind it?

Quite possibly. As children grow, their daytime sleep needs change — some keep napping well into the toddler years, others gradually stop, and some manage fine without a nap on quieter days but still need one after a big morning.

You don't need to make an immediate call on whether the nap is staying or going. Instead, watch what happens afterwards. If they skip the nap and are exhausted and miserable by late afternoon, they probably still need it. If they manage the afternoon fine and settle more easily at bedtime, they may be moving toward less daytime sleep. Either way, there's usually an adjustment period while everyone finds the new rhythm.

How to reset the routine

When sleep changes, it's tempting to overhaul everything at once. Usually you don't need to — start with the parts of the evening your child already knows.

A familiar sequence might look like:

Dinner → quiet play → bath or wash → pyjamas → teeth → books → cuddle → bed

The exact routine matters less than having a sequence your child recognises. A bath is calming for some children and energising for others; some love several books, others do better with one favourite. There's no universally "correct" routine — the idea is just a gradual wind-down from the busyness of the day.

A sample bedtime routine

Every family's schedule looks different, so treat this as an example, not a timetable to copy:

5:30 pm: Dinner

6:00 pm: Quiet play or family time

6:30 pm: Bath or wash and pyjamas

6:45 pm: Brush teeth, choose a couple of books

7:00 pm: Story and cuddle

7:10 pm: Into bed

After bedtime: Keep responses calm and predictable

Your child's age, nap pattern, childcare schedule, and individual needs might mean yours looks nothing like this — that's fine. The goal is familiarity, not a perfect schedule.

What if they keep getting out of bed?

This is one of the more exhausting parts of a sleep regression. It's tempting to explain, negotiate, or get increasingly frustrated — but the more interesting bedtime becomes, the harder it can be to bring it back to a quiet routine.

A simple response is usually enough:

"It's bedtime now. Back to bed."

Then calmly walk them back. You don't need the perfect phrase — just a reasonably predictable one.

This comes up a lot around the cot-to-bed transition. Your child has suddenly gained a new kind of freedom, and naturally, they want to explore it. That doesn't mean bedtime has to become a battle — you can acknowledge the growing independence while still keeping the boundary clear.

What about night waking?

Night waking can be unsettling, especially after a stretch of sleeping through. Before assuming you've created a new habit, consider what else might be going on — a developmental leap, illness, something new at home, or a need for reassurance after a new experience.

A toddler may genuinely need more help settling for a while without that becoming permanent. Keeping things quiet and low-key overnight helps them recognise that waking up is different from starting the day — a cuddle, a brief reassurance, or your usual settling approach may be all it takes. If you've been offering more support than usual, you can ease back toward your normal routine once things settle.

And 5am wake-ups?

Early waking is particularly grating because it can feel like your toddler has simply decided the day starts before everyone else is ready. Before changing bedtime, look at the bigger picture: has the nap shifted? Is bedtime now earlier or later? Is light coming into the room? Has the household routine changed? Could they be uncomfortable or unwell?

If they're otherwise settled, keeping the room quiet and treating the early wake as still-night for a while can help reinforce the difference between waking and getting up. There's no single fix here — sometimes a small adjustment to the overall routine does more than simply moving bedtime later.

Keeping home and childcare connected

Toddlers move across different environments each day, so it helps when the adults around them are on the same page. Families can let educators know about things like a new nap pattern, signs their child is tired, a bedtime change, or recent changes at home.

The routine doesn't need to match exactly — childcare has its own rhythm, and every child's needs differ. What matters is an open conversation, so everyone understands how the child is managing across the whole day. A toddler struggling with sleep at home may have had a particularly full day at childcare, and observations from educators can offer useful clues too.

When to seek professional advice

Most changes in toddler sleep respond to patience, observation, and a return to familiar routines — but you don't have to work it all out alone. If disruption is persistent or severe, or you're concerned about your child's health or wellbeing, speak with your GP or another appropriate healthcare professional — particularly if there are persistent breathing difficulties, unusual breathing during sleep, significant disruption, ongoing discomfort, or other health concerns.

The key takeaway

If your toddler suddenly stops sleeping the way they used to, you're not necessarily doing anything wrong. Toddlers are changing constantly — their independence, their communication, their experiences, their daytime sleep needs — and their sleep often changes right along with everything else.

Instead of hunting for a single cause or trying to fix everything overnight, start with what's changed. Are they becoming more independent? Ready for a different nap pattern? Adjusting to something new in their routine? Just wanting a bit more reassurance? A familiar evening rhythm, a calm response, and a little patience can give them room to adjust while you find their new normal.

FAQs about toddler sleep regression

Is toddler sleep regression real?

It's a term parents use rather than a formal diagnosis. Sleep can genuinely become harder alongside development, changing naps, separation, illness, or routine changes.

How long does it last?

No standard duration — it may settle quickly for some children and take longer for others. If it persists or is significantly affecting your family, talk to a healthcare professional.

Is there a set age it happens at?

There isn't a fixed age. Sleep can change around two or three as children become more independent, develop new communication skills and begin to need different amounts of daytime sleep.

Why is my toddler suddenly fighting bedtime?

It could be growing independence, shifting daytime sleep, wanting more connection at day's end, or a routine change. Looking at the whole day usually tells you more than focusing on bedtime alone.

Should I wake my toddler from a nap?

Not necessarily — it depends on their individual pattern and how the nap affects the rest of their day. If you're unsure or naps keep disrupting bedtime, a healthcare professional can help you weigh it up.

What should I do if my toddler won't sleep?

Start with what's changed, keep the evening familiar, avoid turning bedtime into a negotiation, and give them time to adjust. If settling stays genuinely difficult, get professional input.

What can I do about night waking?

Keep interactions quiet and predictable, offer the reassurance they need, and think about what might have recently changed. Seek advice if it's persistent or concerning.

When should I worry?

Persistent or severe disruption, breathing difficulties during sleep, ongoing discomfort, or other health concerns are worth raising with a professional.
