Why Your Little One Can Not Sleep Through the Night
If you’re struggling with a little one who can not sleep through the night, I want to let you in on a little secret: everyone wakes up during the night. Kids, babies, even adults (Here is a blog post I wrote about adults waking throughout the night). It’s totally normal—and actually part of how our sleep works. Each night, we all go through several sleep cycles, and in between those cycles, our bodies are biologically programmed to briefly wake up. It’s a built-in safety precaution that goes way back in our evolutionary wiring—a quick check to make sure everything around us is still safe and sound before we dip into the next cycle.
For most of us, these little wake-ups are so quick we don’t even remember them. We shift, readjust, and drift right back to sleep. But for our little ones, that’s not always how it goes. And that’s where the real issue lies. It’s not the waking up—it’s the not being able to fall back asleep that’s causing all the nighttime drama.
So the real question isn’t why your little one is waking up—because those brief wakings are totally normal. The real question is why they’re having trouble getting back to sleep. There’s almost always a reason they’re getting stuck in the middle of the night, and once we figure out what’s getting in their way, we can help them move past it.
In this blog, I’m going to walk you through the top 5 reasons I see kids getting tripped up when it comes to falling back asleep in the middle of the night. Some of the solutions are pretty straightforward, and others may take a little more intention, effort, and consistency—but I promise, it’s worth it.
1. They don’t know how to fall back asleep on their own
Let’s start with a biggie: Does your child know how to fall asleep by themselves—without needing your help or a very specific setup that might not be there later in the night?
Now don’t get me wrong—white noise, a favorite lovey, or a cozy blankey? Those aren’t problems. They’re actually great if they help your little one relax and drift off. The catch is this: whatever helps your little one fall asleep at bedtime needs to be there when they wake up in the middle of the night, too.
For example, maybe white noise is playing at bedtime, but it shuts off a few hours later. Or your little one falls asleep in your arms on the couch, and then wakes up confused in their crib. Or maybe you sing them to sleep each night, but of course, you’re not there humming sweet lullabies at 2:00am.
When the bedtime setup doesn’t match the middle-of-the-night reality, that inconsistency can be confusing—and that’s usually when your little one calls for you to recreate the scene.
The fix: Try to keep bedtime and nighttime wake-ups as similar as possible. If they fall asleep in their bed with white noise playing and a lovey in hand, that same setup should be waiting for them when they stir later on. If you are the one helping them all the way to sleep at bedtime, it makes sense they’d come looking for you again when they wake up. That doesn’t mean ditching all the snuggles and connection time—just shifting the final moment of falling asleep into their own hands, in the same space and with the same tools they’ll have access to all night long.
2. They believe only you can help them fall asleep
Our little ones are incredibly smart. And loving. And totally attached to us. They know when something hurts, only a kiss from mom or dad will make it better. But sometimes that belief spills over into night wakings, too—“I can’t go back to sleep unless Mommy helps me.”
And sure, if this only happens occasionally and you don’t mind swooping in for a middle-of-the-night snuggle, that’s okay! No judgment here (I’m dreading the day my littlest bear stops asking me to kiss his boo boo). But if it’s happening every single night, and it’s cutting into your sleep in a big way, it’s time to shift that belief that “only parents can fix it.”
The fix: Start during the day. Let your little one know that they have a superpower—they can put themselves back to sleep all by themselves. Make it fun. Create a mantra or affirmation together that they can say at bedtime: “I am cozy. I am sleepy. I can fall asleep all by myself.”
Practice this confidence during the day and weave it into your bedtime routine. You might still get a few middle-of-the-night calls at first, but gentle reminders and consistency will help them start to believe it.
3. A new fear or anxiety is showing up at night
One day your little one is snoozing like a champ, the next they’re waking up scared and calling for you, wide-eyed and panicked. What gives?
When a child who usually can sleep through the night suddenly can not sleep through the night, a new fear or anxiety might be to blame. Maybe it’s nightmares, a scary story from preschool, or a big life change (new sibling, new house, potty training). And while our instinct is often to solve it in the moment, nighttime isn’t the best time for deep talks.
The fix: Offer comfort and reassurance in the moment, but keep the conversation light and calming. Then, during the day, when everyone’s more regulated, try to get to the root of the fear. Was there a triggering event? Is something happening during the day that’s carrying into the night?
If it’s something serious or traumatic, absolutely bring in a professional. But if it’s a common kid worry, help them name it, normalize it, and work through it—all in the daylight.
4. Something environmental is throwing things off
Even the smallest change in your little one’s sleep environment can make a big difference in how well they’re able to fall back asleep. What felt cozy and perfect at bedtime may feel totally different at 2am.
Maybe:
- Their white noise machine shut off.
- The room got chilly.
- A sliver of hallway light is sneaking in and messing with their melatonin.
These things can all make it harder for your little one to fall back asleep once they naturally wake between sleep cycles.
Fun fact: the light that our eyes pick up on in the middle of the night effects our melatonin production more than the light our eyes sense earlier in the day. So even if the little, blue indicator lights on electronics don’t bother your little one (or you!) at bedtime, they could still cause trouble with falling back to sleep in the middle of the night!
The fix: During one of those middle-of-the-night wake-ups, do a quick room audit. Is the soundscape the same as it was at bedtime? Has the temperature dropped or rose? Is there unexpected light from a device, hallway, or street lamp?
Try to make the environment as consistent and sleep-conducive as possible from bedtime through morning.
5. Their body’s hormones are making it harder to fall back asleep
Here’s a little sleep science: to fall asleep, we want our melatonin (sleepy hormone) and adenosine (sleep pressure) to be high, and our cortisol (stress hormone) to be low.
But in the middle of the night, those sleepy hormones are naturally lower, which is why falling back asleep can feel trickier. Now if cortisol spikes, whether due to stress, excitement (hello, Christmas Eve!), or even a blood sugar crash from a sugary bedtime snack, it becomes way harder to slip back to sleep.
The fix: Keep bedtime snacks balanced—aim for protein and complex carbs over sugar, especially in the two hours before bed. If your little one seems stressed or overstimulated at bedtime, build in calming rituals like breathwork or a gentle bedtime story. One trick I love? Belly breathing with a favorite stuffed animal. Watch it rise and fall on their tummy—it’s like a mini meditation.
So… Is waking up at night a bad thing?
Nope! Not at all. We all wake up between sleep cycles. But when your little one can not sleep through the night because they can’t get themselves back to sleep without help, and it starts happening night after night… that’s when it becomes a problem worth solving.
By figuring out which of these five culprits might be showing up in your family’s nights—and making some mindful shifts—you can help your little one sleep better and longer. And that means you get more rest too. Which, let’s be honest, you 1000% deserve. 💜🧸
