Why does my toddler wake up crying every single night? Many parents ask this. It’s a tough problem. When a toddler wakes up crying at night, it can be very tiring for the whole family. This happens for many reasons. Sometimes it is just part of how little kids sleep. Other times, something else is going on. We will look at common toddler night waking causes. These can include going through sleep changes, feeling scared, or not feeling well.
It helps to know why your little one is crying at night. This way, you can figure out the best way to help them. It might be a quick fix, or it might take more time. Let’s find out what could be making your toddler wake up upset when the house is quiet.

Grasping Toddler Sleep
First, let’s talk about how toddlers sleep. Their sleep is not like adult sleep. Babies and toddlers have shorter sleep cycles. This means they go in and out of light and deep sleep more often. When they are in light sleep, it is easier for them to wake up fully.
Think of sleep like climbing stairs. You go up (fall asleep), walk around on a level (light sleep), go up again (deep sleep), walk around (light sleep), and so on. Adults do this too. But toddlers do it faster. Each ‘level’ or cycle is about 60-90 minutes for them. Between cycles, they might briefly wake up.
Usually, a toddler who sleeps well can easily go back to sleep on their own during these brief awakenings. But if something is bothering them, they might wake up fully and need help. Crying is their way of saying, “Something’s wrong!”
So, waking up is normal. Crying when they wake up is the part we need to understand.
Interpreting Common Toddler Night Waking Causes
Lots of things can make a toddler wake up crying. It could be something simple or something needing a little more attention. Here are some main reasons:
- Feeling scared or worried.
- Having growing pains, like teething.
- Feeling sick.
- Being too hot or too cold.
- Their sleep schedule is off.
- Getting older and going through sleep changes.
- Feeling hungry or thirsty.
- Needing to go to the bathroom.
- Just needing comfort.
Let’s look closely at some of the most common reasons your toddler wakes up crying at night.
When Sleep Gets Tricky: Sleep Regression
This is a very common reason for toddler night waking. A sleep regression toddler might have been sleeping great. Then, all of a sudden, they start waking up crying many times at night. They might also fight naps or bedtime.
What is a sleep regression? It’s a time when a toddler’s sleep gets worse for a while. It often happens when they are learning new things. These new skills can be sitting up, crawling, walking, or talking. Learning takes a lot of brain power! This active brain can make it harder for them to settle down and stay asleep.
Common ages for sleep regressions are around:
* 4 months (often called the 4-month regression, though this is more about sleep cycles changing)
* 8-10 months
* 12 months
* 18 months
* 2 years
The 18-month and 2-year regressions are very common for toddlers. At 18 months, they might be learning to walk or talk a lot. They might also start having separation anxiety. At 2 years old, they are learning so much and testing limits. This brain activity can mess with sleep.
Signs of a toddler sleep regression:
* Waking up more at night.
* Crying when they wake up.
* Fighting bedtime or nap time.
* Shorter naps or no naps.
* Being more clingy during the day.
Sleep regressions are usually temporary. They might last a few weeks. The key is to stick to your normal sleep rules and routine. Don’t start new habits (like bringing them to your bed every time) that are hard to stop later. Offer comfort, but try to help them go back to sleep in their own bed.
Scary Dreams: Night Terrors and Nightmares
Both nightmares and night terrors can make a toddler wake up crying. But they are very different.
Nightmares: These are bad dreams. They usually happen during the second half of the night, when sleep is lighter. If your toddler has a nightmare, they will wake up fully. They will be scared and might cry hard. They will remember the dream. They will need your comfort and help to feel safe again. You can hug them, talk gently, and help them feel okay.
Night Terrors: These are much scarier to watch. They happen in deep sleep, usually in the first few hours after falling asleep. During a night terror, your toddler might:
* Scream or yell.
* Sit up in bed or thrash around.
* Have their eyes open but look like they are not seeing you.
* Sweat a lot.
* Have a fast heartbeat.
* Be hard to wake up.
* Push you away if you try to hold them.
Even though it looks like they are awake and terrified, they are actually still asleep. They do not remember the night terror when they wake up in the morning.
Soothing toddler night terrors is different from soothing nightmares. With a night terror, do not try to wake them up. This can make it worse or make them scared and confused if they do wake up. The best thing to do is:
1. Stay calm.
2. Make sure they are safe (not going to fall out of bed, etc.).
3. Wait for it to pass. This usually takes only a few minutes.
4. Do not try to comfort them much or talk to them. They aren’t really “there” with you.
5. Once it is over, they will usually lie back down and go into deeper sleep.
Night terrors can be linked to being overtired or having a fever. Keeping a regular sleep schedule can sometimes help prevent them. Nightmares are a normal part of growing up.
| Feature | Nightmare | Night Terror |
|---|---|---|
| When it happens | Second half of the night | First few hours of sleep |
| Sleep state | Wakes child fully | Child stays asleep |
| Child’s state | Scared, remembers dream, needs comfort | Looks terrified, doesn’t remember, hard to reach |
| What to do | Comfort them awake, talk gently | Stay calm, ensure safety, wait it out |
Missing You at Night: Separation Anxiety
Toddlers are very attached to their parents. As they get older, they realize they are separate people from you. This is a normal and important part of growing up. But it can also cause separation anxiety.
Separation anxiety toddler sleep problems happen when your child gets upset about being away from you. This often gets worse around 18 months. At night, when they are alone in their room, they might wake up and feel scared or worried that you are not there. They might cry for you.
Signs of separation anxiety affecting sleep:
* Crying or clinging when you leave the room at bedtime.
* Waking up at night crying and calling for you.
* Being hard to comfort unless you stay in the room.
* Wanting to sleep in your bed.
How to help with separation anxiety toddler sleep issues:
* Have a solid bedtime routine. This helps them feel safe and know what to expect.
* Practice short separations during the day. This helps them learn you always come back.
* Give them a lovey or special blanket to sleep with (if safe for their age).
* When they wake up crying, go to them quickly to let them know you are there.
* Keep visits short and calm. Reassure them you are there and it’s time to sleep. Avoid long talks or playing.
* Gradually spend less time in the room when they wake up, if you choose. Or just go in, offer a quick pat, say “Mommy/Daddy is here, you are safe, time to sleep,” and leave.
Consistency is key here. Let them know you are there, but also that night is for sleeping.
Aches and Pains: Teething and Illness
Physical discomfort is a big reason for a toddler to wake up crying at night. They can’t tell you what hurts, so they cry.
Toddler Teething Sleep Problems: Teething pain is a very common culprit. New teeth cutting through gums hurt! This pain can be worse at night when there are no other distractions.
Signs of teething pain:
* More drooling.
* Chewing on things.
* Swollen, red gums.
* Fussiness.
* Slight fever (check with a doctor if concerned).
* Waking up crying at night.
How to help with toddler teething sleep problems:
* Offer a cold teething toy before bed.
* Rub their gums gently.
* Talk to your doctor about safe pain relief options like infant acetaminophen or ibuprofen (especially before bed if pain is bad). Use medicine only as directed and not every night.
Illness: Sickness like a cold, ear infection, or stomach bug can really mess up sleep. A toddler ear infection sleep is often disturbed because lying down can make the pain worse due to pressure in the ear. A stuffy nose makes breathing hard. A fever makes them feel uncomfortable.
Signs of illness affecting sleep:
* Coughing or sneezing.
* Runny nose.
* Fever.
* Pulling at ears (possible ear infection).
* Vomiting or diarrhea.
* Being more clingy or tired during the day.
* Waking up crying more often at night.
If your toddler wakes up crying and seems sick, check their temperature and look for other signs.
* For colds: Use a humidifier, offer fluids during the day, clear stuffy noses with saline drops and a nasal aspirator before bed. Keep head slightly raised if possible.
* For ear infections: Pain is common. Follow your doctor’s advice for medicine. Pain relief can help them sleep.
* Always talk to your doctor if you think your child is sick, especially with a fever, ear pain, or if they seem very unwell. Treating the sickness is the first step to getting sleep back on track.
Tummy Troubles: Hunger or Thirst
Most toddlers past a year old do not need to eat during the night if they eat enough during the day. But sometimes, a toddler waking up hungry night happens.
Why might a toddler wake up hungry?
* They didn’t eat enough dinner or had dinner too early.
* They are going through a growth spurt.
* They rely on a bottle or milk to fall asleep, and when they wake between cycles, they need it again to go back to sleep (this is more of a sleep habit issue).
If your toddler is truly waking up hungry night after night past 12-18 months, it’s worth looking at their daytime food intake. Are they eating balanced meals and snacks? Are they drinking too much milk or juice that fills them up but doesn’t give lasting energy?
For most toddlers over 1 year, offering a small snack before bed (like yogurt, cheese, or toast) can help them last the night. Waking for a drink of water is more likely than true hunger after 18 months, especially if they have a comfort item like a water bottle.
If you think hunger is the issue, offer a snack before the bedtime routine starts. Avoid feeding them in the middle of the night unless advised by your doctor. Feeding them every time they wake can teach their body to expect food at night.
Too Much or Too Little Sleep: Overtired or Undertired
It sounds strange, but being overtired toddler waking night is very common. When toddlers don’t get enough sleep during the day (short naps) or go to bed too late, their bodies produce stress hormones like cortisol. These hormones can make it harder to fall asleep and stay asleep. An overtired child might actually wake up more at night and be harder to settle.
Signs an overtired toddler is waking at night:
* Rubbing eyes, yawning, fussy long before bedtime.
* Getting a “second wind” and becoming hyper near bedtime.
* Taking a long time to fall asleep.
* Waking up crying shortly after falling asleep.
* Waking up many times during the night.
* Waking up very early in the morning.
On the flip side, an undertired toddler might also wake up crying. If they slept too much during the day or went to bed too early when they weren’t tired enough, they might wake up in the middle of the night wide awake and unhappy.
How to find the right sleep balance:
* Learn your toddler’s sleep needs. Most toddlers need 11-14 hours of sleep in a 24-hour period (including naps).
* Watch for their tired signs. Put them to bed when they first show sleepy cues, not later.
* Make sure naps are long enough. If naps are short, an earlier bedtime is key to prevent overtiredness.
* Be consistent with bedtime. Going to bed around the same time each night helps regulate their body clock.
Figuring out the right sleep schedule is crucial for preventing overtired toddler waking night cycles.
Changes and Stress
Toddlers thrive on routine. Any big change can cause stress or upset, which can then show up as night waking and crying.
Changes that might affect sleep:
* A new sibling.
* Moving to a new house.
* Starting daycare or a new school.
* A parent traveling.
* Changes in who takes care of them.
* Learning a big new skill (like potty training).
* Changes in the daily schedule.
These things can make a toddler feel less secure or just more stimulated. Their brain processes these changes at night, which can lead to waking up crying.
How to help:
* Keep the bedtime routine extra consistent during times of change.
* Spend extra one-on-one time with them during the day to help them feel secure.
* Talk about the changes in simple, positive ways (if they can understand).
* Be patient. It takes time to adjust to new things.
Sleep Habits and Toddler Sleep Training Crying
Sometimes, night waking isn’t about hunger or pain, but about how your child falls asleep. If a toddler needs a specific thing or person to fall asleep at bedtime (like being rocked, nursed, or held until fully asleep), they might need that same thing when they naturally wake between sleep cycles during the night. If it’s not there, they cry. This is often called a “sleep association” or “sleep prop.”
Toddler sleep training crying is about teaching your child how to fall asleep on their own and go back to sleep independently during the night. It involves changing those sleep associations.
How this leads to crying: When you change the way they fall asleep (e.g., putting them down awake instead of asleep), they protest because it’s different and they don’t know how to do it yet. The crying is often a sign of frustration or protest as they learn this new skill.
Different methods of sleep training involve different amounts of crying:
* Gradual methods: Involve staying with your child and slowly reducing your help. This might involve less intense crying over a longer time.
* Extinction methods: Involve putting your child down awake and leaving, checking on them at set times or not at all. This might involve more intense crying upfront but potentially faster results.
Is toddler sleep training crying “bad”? This is a topic parents feel strongly about. Most sleep experts agree that some crying is often part of the process of learning independent sleep. The goal is not to let your child cry for hours with no comfort. The goal is to teach them a skill. You need to choose a method you are comfortable with and be consistent.
If you decide to try sleep training:
1. Make sure your child is not sick, teething badly, or going through a major life change.
2. Have a solid bedtime routine.
3. Put your child down awake.
4. Follow your chosen method consistently for night wakings as well.
5. Be prepared for crying. It’s the child’s way of protesting change.
6. Know that it takes time and consistency.
If your toddler was sleeping well and suddenly starts waking and crying after you made a change to their sleep routine (like stopping rocking), this could be protest related to sleep habits.
Deciphering Other Reasons for Crying
Beyond the main causes, other things can make a toddler wake up crying:
- Temperature: Is the room too hot or too cold? Toddlers sleep best in a cool room (68-72°F or 20-22°C). Check if they feel too warm or cold to the touch, not just their hands or feet.
- Too Much Light or Noise: Is light coming into the room too early? Is there sudden noise (a dog barking, traffic)? Blackout curtains and a white noise machine can help block out light and confusing sounds.
- Needing to Potty: Older toddlers who are potty training might wake up needing to go. Taking them quickly and calmly to the potty (without making it playtime) can help. For younger toddlers still in diapers, a wet or dirty diaper can cause discomfort.
Steps to Take When Your Toddler Wakes Up Crying
It’s the middle of the night. Your toddler is crying. What should you do?
- Pause and Listen: Is it just a brief cry as they shift between sleep cycles? Or is it a full, distressed cry? Sometimes, they might resettle themselves in a minute or two.
- Check for Basic Needs: Go to them calmly. Quickly check if they are too hot/cold, if their diaper is wet/dirty, or if they seem sick (fever, coughing).
- Assess the Situation: Are they standing in the crib calling for you? Do they seem confused or scared (maybe a nightmare)? Are they thrashing but eyes glazed (maybe a night terror)?
- Respond Calmly and Consistently:
- If sick/teething: Offer comfort. Give medicine if needed and approved by doctor. Address the physical discomfort. They might need more cuddles when unwell.
- If a nightmare: Go to them right away. Offer comfort, hugs, gentle words. “It was just a bad dream. You are safe. Mommy/Daddy is here.” Help them feel secure and guide them back to sleep in their bed.
- If a night terror: Do not wake them. Ensure they are safe. Wait it out quietly. Do not try to comfort them or talk to them much while they are in the terror.
- If separation anxiety/habit related: Go in quickly and calmly. Reassure them you are there (“Mommy/Daddy is here, you are safe, time for sleep”). Keep it brief. Avoid turning on lights, playing, or long talks. Put them back in their bed if they are out. Leave the room. You might need to repeat this or use a sleep training method you are comfortable with. Consistency is key for these types of wakings.
- If overtired/undertired: Address the root cause by adjusting the sleep schedule over time. For the night waking, respond calmly and guide them back to sleep using your usual method.
Important: Avoid starting new habits in the middle of the night that you don’t want to continue. Bringing them into your bed every time they cry might feel easier in the moment, but it can quickly become the new expectation. If you are okay with co-sleeping, that’s a different story. But if you want them to sleep in their own bed, try to always return them to their bed after checking on them.
When to Seek Help
Most toddler night waking causes are normal and temporary. However, if your child’s night waking:
* Suddenly gets much worse and lasts for more than a few weeks without a clear cause (like illness).
* Is linked to other concerning symptoms during the day (poor eating, low energy, strange behavior).
* Is happening with very loud snoring or pauses in breathing (could be sleep apnea).
* Is making you feel unable to cope due to lack of sleep.
Talk to your pediatrician. They can check for medical reasons (like chronic ear infections, allergies, or sleep apnea) and offer advice or refer you to a sleep specialist.
A certified child sleep consultant can also be a great help if you suspect the issue is mostly related to sleep habits, schedules, or sleep training crying strategies. They can help you create a plan tailored to your family.

Fostering Better Night Sleep
While addressing the specific cause is important, having good general sleep habits helps all toddlers sleep better.
Creating a Relaxing Bedtime Routine:
This signals to your toddler that it’s time to wind down. It should be the same steps, in the same order, every night.
* Bath (optional)
* Pajamas and diaper/potty
* Brushing teeth
* Reading books
* Quiet cuddles or songs
* Into the crib/bed awake
Keep it short (20-30 minutes) and calm.
Setting the Sleep Environment:
* Dark room (blackout curtains are helpful).
* Cool temperature.
* White noise machine to block out sounds.
* Safe sleep space (crib or bed without loose blankets/pillows for younger toddlers).
Consistency is Key:
Go to bed and wake up around the same time each day, even on weekends. Regular naps are important too. A predictable schedule helps regulate their body clock.
Teaching Independent Sleep:
If your toddler relies on you heavily to fall asleep, teaching them to fall asleep on their own is crucial for them to connect sleep cycles during the night without crying for help. This is where sleep training methods come in, if you choose to use one.
Crying is how toddlers communicate. When they wake up crying at night, they are telling you something. By trying to figure out the reason – be it a sleep regression toddler phase, scary night terrors toddlers might experience, separation anxiety toddler sleep issues, toddler teething sleep problems, a toddler waking up hungry night, a painful toddler ear infection sleep disruption, an overtired toddler waking night pattern, or even crying that comes with toddler sleep training crying – you can offer the right kind of help and comfort. Patience, consistency, and sometimes a little detective work are your best tools.
Frequently Asked Questions
Q: Is it normal for a toddler to wake up crying?
A: Yes, it is very normal for toddlers to wake up at night. Crying is their way of showing they need help or comfort. The reason for the crying is what you need to figure out.
Q: How long does a sleep regression last?
A: Sleep regressions usually last for 2 to 6 weeks. The key is to stick to your routine and not create new sleep habits that you will need to break later.
Q: What’s the difference between a night terror and a nightmare?
A: A nightmare is a bad dream that makes the child wake up fully, scared, and they remember it. A night terror happens while the child is still in deep sleep; they look terrified but are not awake and don’t remember it. You comfort a child after a nightmare but mostly ensure safety and wait it out during a night terror.
Q: Should I pick up my toddler every time they cry at night?
A: This depends on why they are crying and your approach to sleep. If they are sick or had a nightmare, yes, pick them up and comfort them. If it’s a habit-related waking after checking they are safe and well, picking them up every time can reinforce the need for you to fall back asleep. Many parents choose to check on them in the crib and offer quick, calm reassurance instead.
Q: Could teething really cause so much night waking?
A: Yes, absolutely. Teething pain can be intense, and like other aches, it can feel worse at night without daytime distractions.
Q: When should I be worried about my toddler’s night waking?
A: Talk to your doctor if the waking is sudden and extreme, lasts for a long time without clear cause, is linked to daytime health issues, involves difficulty breathing, or if you are struggling to cope with the lack of sleep.
Q: Can overtiredness really cause more waking? It seems backwards.
A: It does seem backwards! But yes, being overtired floods the body with stress hormones that make it harder to fall asleep and stay asleep peacefully. An overtired child is more likely to have disrupted sleep.
