Toddler sleep regression can turn peaceful bedtimes into nightly battles that leave everyone exhausted. Your toddler who once went to bed easily is now stalling, calling out repeatedly, or waking up multiple times during the night wanting you.
These sleep disruptions aren't random—they happen at predictable ages as your toddler's brain develops and they test boundaries. Understanding when these regressions typically occur and why they happen can help you respond with confidence instead of frustration.
You'll discover the telltale signs of toddler sleep regression, learn which ages are most affected, and get practical strategies to help your toddler (and you) sleep through the night again.

Signs Your Toddler Is Going Through Sleep Regression
Sleep regression pops up in a few recognizable ways that mess with your toddler's usual sleep habits. You might see more resistance at bedtime, extra wake-ups, and changes to their morning or nap routines.
Bedtime Battles and Stalling Tactics
Your toddler might suddenly fight bedtime, even if it used to be smooth sailing. Expect requests for more water, another story, or yet another trip to the potty. These classic stalling moves are dead giveaways for sleep regression.
You could notice more crying, tantrums, or just plain clinginess at bedtime. Maybe your kid keeps getting up after you say goodnight, or insists you stay in the room until they're asleep. Sometimes, they get upset the moment you try to leave.
Common bedtime resistance behaviors include:
- Asking for extra hugs or kisses
- Insisting they're not tired
- Saying they're scared or need you nearby
- Taking way longer to fall asleep
Usually, these behaviors crop up even if you haven't changed your bedtime routine. The change tends to be pretty sudden.
Frequent Night Wakings and Calling Out for Parents
Your toddler might start waking up a lot during the night, even if they used to sleep straight through. They could call out for you, cry, or wander into your room looking for comfort. Sometimes these wake-ups happen like clockwork, other times they're all over the place.
Some kids wake up fully and can't get back to sleep without help. Others seem confused or upset when they wake. You might find your child standing at their door or sitting up in bed calling for you.
Night wakings can range from once or twice to several times a night. Your child might need extra comfort or reassurance to settle down. They may ask to sleep in your bed or want you to stay with them until they drift off again.
Early Morning Wake-Ups and Nap Refusal
Your toddler might start waking up much earlier than usual. Instead of sleeping until 7 AM, they're up and ready to go at 5 or 5:30. These early mornings leave them tired but unable to catch up on sleep.
Nap resistance often tags along with sleep regression. Your child could refuse their usual nap or only nap for a short time. They might fight naptime with just as much energy as bedtime, even if they're clearly tired.
Some toddlers skip naps altogether, which leads to overtiredness later in the day. That, in turn, makes bedtime even harder. You might notice your child is crankier or just out of sorts because they're not getting enough rest.

Common Ages for Toddler Sleep Regression
Sleep regressions tend to hit at certain ages, usually tied to your child's milestones. Most often, you'll see these disruptions around 18 months, 2 years, and 3 years.
18-Month Sleep Regression
At 18 months, your toddler's learning words like crazy, walking with more confidence, and figuring out their independence. All this keeps their brain buzzing, even at bedtime.
Separation anxiety usually peaks now. Your child might cry or resist when you leave at night, or wake up looking for you.
Growth spurts can also shake things up. Your toddler might wake up hungry or just need extra comfort. These physical changes can throw off their normal sleep.
This regression generally lasts two to six weeks. Your child might fight bedtime, skip naps, or wake up more often at night. Some kids start having their first real nightmares, too.
2-Year Sleep Regression
The 2-year sleep regression can really sneak up on you. Your toddler's busy testing boundaries and figuring out their independence. They might say "no" to bedtime or try to stretch out the routine with more stories.
Many kids start dropping their afternoon nap or resisting it. That can make them overtired by bedtime, which weirdly makes it even harder to sleep. Potty training can also cause nighttime wake-ups.
Your child's imagination is growing, too. They might start getting scared of the dark or worried about monsters. These fears can make bedtime tougher and cause more night wakings.
This regression can stick around for three to six weeks. You might notice your toddler climbing out of their crib, calling for you over and over, or waking up super early.
3-Year Sleep Regression
The 3-year sleep regression isn't as common, but plenty of kids go through it. Now your child can talk about their feelings and fears. Sometimes, they get pretty creative with reasons to avoid bedtime.
Nightmares and night terrors show up more at this age. Your child's imagination can make scary things feel very real. They might wake up upset and need you to calm them down.
Lots of 3-year-olds are ready to drop their nap completely, which can temporarily throw off their nighttime sleep. Some kids get overtired and then struggle even more to settle down at night.
This regression usually lasts two to four weeks. Your child might stall at bedtime, wake up in the night, or come into your room early in the morning.
How to Handle Toddler Sleep Regression
Getting through sleep regression means holding firm on boundaries, handling nighttime bathroom trips, and keeping your child comfortable.
Set Clear and Consistent Sleep Boundaries
Your toddler needs to know what to expect at bedtime. Stick to a routine that happens at the same time and follows the same steps—maybe a bath, teeth brushing, a couple of books, then lights out.
Be firm about when bedtime starts and ends. If your toddler gets up, walk them back calmly without making a big deal. Keep your voice low and your actions quick.
Key boundaries to set:
- Same bedtime and wake time every day
- Rules about staying in bed
- Limits on water, snacks, or extra stories
- Consistent response when rules are tested
Your toddler will push these boundaries—it's not defiance, just learning where the lines are. They're figuring out if you'll actually stick to the rules.
When your child tests you, keep your response calm and brief. Honestly, the more boring and predictable bedtime is, the quicker your child learns that nighttime's for sleeping, not playing or chatting.
Manage Nighttime Bathroom Trips with Quick Changes
Potty training can mess with sleep if your toddler needs to use the bathroom at night. Keep these trips short and boring so your child can get back to sleep fast.
Use a small nightlight in the hall or bathroom, not the bright overhead light. Bright lights tell your child's brain it's time to wake up.
Keep pajamas, wipes, and other supplies close by to cut down on time spent awake.
Don't turn bathroom breaks into social time. Skip the chatting and games. Just help your child use the toilet, wash hands, and get them back to bed with as little fuss as possible.
Keep Your Toddler Comfortable with Overnight Protection
Physical discomfort wakes kids up and makes it tough to settle down again. Overnight diapers or training pants help prevent wet pajamas and sheets.
Pick products made for overnight—they hold more than daytime options. If your child leaks through, you'll end up changing sheets and pajamas, which wakes them up even more.
Try to keep your child's room between 68-72°F. Dress them in breathable pajamas that fit the room temp. Too hot or too cold? That can mean more night waking.
Check if your child's mattress and bedding feel comfy. Some toddlers care a lot about how heavy their blanket is or how firm their pillow feels—those little preferences really do matter for sleep.
Make quick nighttime changes easier with Alppi Baby's hypoallergenic wipes. Gentle on sensitive toddler skin and perfect for fast bathroom trips that won't fully wake your child.
Conclusion: Toddler Sleep Regression
Toddler sleep regression is exhausting, but it's temporary and manageable with the right approach. Most regressions last 2-4 weeks as your toddler adjusts to new developmental stages. Stay consistent with boundaries, keep your responses calm, and remember that better sleep will return.
During these challenging phases, having the right tools makes nighttime disruptions easier to handle. Quick bathroom trips and comfortable overnight protection help minimize wake-ups and get everyone back to sleep faster.

Frequently Asked Questions: Toddler Sleep Regression
Sleep regressions leave parents with a lot of questions. Here are some quick answers about timing, causes, and what you can actually do to help your toddler sleep better.
What age do toddlers have sleep regression?
Most toddlers hit sleep regressions around 12-18 months, 2-3 years, and sometimes 4-5 years old. The 18-month regression happens as toddlers develop new skills like walking and talking, keeping their brains active even during sleep. Each regression typically lasts 2-6 weeks, though every child is different.
Why has my 2 year old stopped sleeping?
Separation anxiety ramps up at 2 years, and rapid language development makes it hard for their brain to shut off. Physical changes like switching from crib to bed or dropping naps can leave them overtired or too free to roam. New siblings, starting daycare, or teething molars can also disrupt sleep unexpectedly.
How to help a toddler fall asleep?
Start with a simple, consistent bedtime routine—3 to 5 calming steps in the same order every night. Make the bedroom sleep-friendly with blackout curtains, 68-72°F temperature, and white noise if needed. Stick to a regular sleep schedule, cut screen time an hour before bed, and encourage active daytime play.
What are signs of sleep disorders in children?
Sleep disorders need medical attention—watch for loud snoring, pauses in breathing, or excessive daytime sleepiness despite adequate nighttime sleep. Regularly taking more than 30 minutes to fall asleep for months, night terrors where your child screams but doesn't wake, or restless leg movements are red flags. If sleep issues persist beyond six weeks or you notice these signs, talk to your pediatrician.
