Managing Baby and Toddler Sleep Regression

Written by Katy Arnold on February 27, 2025.

Sleep regression in babies can turn a solid sleep routine into an unpredictable free-for-all. Just when you think you’ve nailed everyone’s schedules—boom—your little one decides bedtime is optional, naps are negotiable, and 3 a.m. is the perfect time to hang out. Baby sleep regression is a common developmental phase, but that doesn’t make it any less exhausting.

The good news? It won’t last forever, and once you know what’s causing the chaos, you can tackle it with a plan—and maybe reclaim some of your own sleep in the process.

What Is Sleep Regression?

You thought you had bedtime figured out—then suddenly, your little one decides that sleep is overrated. One day, they’re snoozing like a champ, and the next, they’re up every hour like they’re training for a night shift.

This sudden change isn’t random; it’s a temporary (but frustrating) phase called sleep regression, where a baby’s usual sleep patterns take a hit. Instead of smoothly transitioning between sleep cycles, babies going through sleep regression start waking more often, taking longer to fall back asleep, and sometimes fighting sleep altogether. It’s exhausting—but with the right approach, you can help them adjust and get everyone back on track.

What Causes Sleep Regression in Babies?

Why do babies fight sleep just when you need it the most? Turns out, there’s a reason behind the madness. Sleep regression is usually triggered by big developmental leaps—your baby’s brain is working overtime to master new skills like rolling, crawling, or even just realizing they have toes. Growth spurts, teething, separation anxiety, and shifting sleep cycles can also throw a wrench in their once-predictable snooze schedule. While it’s frustrating, it’s also a sign that your little one is learning, growing, and hitting exciting milestones.

When Do Babies Go Through Sleep Regression?

Sleep regression has a way of showing up just when things start feeling predictable. These phases can happen multiple times during the first few years, usually when your baby hits major developmental milestones.

Here’s when you can expect these delightful shake-ups:

4-month sleep regression: And just like that, sleep got complicated. Your baby’s sleep cycles are maturing, which means they wake up more often and need help settling back down. The days of newborn-style snoozing are officially over.
6-month sleep regression: Just when you start seeing progress, teething starts, rolling becomes their new favorite trick, and suddenly, sitting up is more exciting than sleeping. Your baby’s brain is busy, and sleep is taking a backseat.
14-month sleep regression: Walking, talking (or at least babbling), and a sudden opinion about bedtime? Yep, this one’s fueled by newfound independence and the possibility of dropping a nap.
3-year-old sleep regression: Thought you were in the clear? Not so fast. Toddler fears, potty training, and a sudden resistance to bedtime routines can turn your nights upside down—again.

Each phase is temporary, even if it doesn’t feel like it at 2 a.m. Hang in there, and keep the coffee stocked.

Tips To Handle Sleep Regression Sleep Regression

Sleep regression can feel like a curveball, but with a few tricks and adjustments, you and your little one can navigate the changes and get back to better rest. Whether you’re soothing an overtired newborn or figuring out why your infant is fighting sleep, here are some tips to make things easier for everyone:

Stick to a routine: Babies love predictability. A consistent bedtime routine—bath, books, cuddles—signals that it’s time to wind down.
Watch for sleep cues: Yawning, eye rubbing, or getting extra clingy? That’s your sign to get them down before they’re overtired.
Offer extra comfort: Sleep regressions can be tough on babies. A little extra rocking or soothing can help them feel secure as they adjust to new changes.
Create a cozy sleep space: A dark room, white noise, and a comfy setup can make a big difference in helping your baby settle.
Soothe teething troubles: If your baby’s gums are making sleep a struggle, a good teether can be a game-changer. Try The Teether by Tushbaby to bring some much-needed relief and keep those little hands and mouths busy.
Make those middle-of-the-night wakeups easier: Holding and rocking a restless baby for hours can take a toll on your arms, back, and patience. The Tushbaby Hip Carrier helps distribute their weight so you can soothe them comfortably without wrecking your posture.
Adjust wake windows: If naps are tricky, try tweaking how long they’re awake between sleep periods. Finding that sweet spot between too much and too little wake time can lead to better sleep.

FAQs

Do Infants Sleep More When Teething?

Teething is unpredictable—some babies get extra sleepy, while others act like sleep is just a suggestion. The discomfort from sore gums can make them more tired, but it can also sometimes lead to restless nights and extra fussiness.

If your little one is struggling, check out our guide on how to soothe a teething baby for some relief strategies. And since teething toys are basically in their mouth 24/7, make sure you know how to sanitize teething toys to keep things clean and germ-free.

Do All Babies Go Through Sleep Regression?

Not necessarily—but most will hit a few bumps in the road. Some babies snooze through every milestone like pros, while others suddenly decide sleep is the worst thing in the world. It all depends on their temperament, development, and, let’s be honest, a little bit of luck. But if your baby starts waking up more at night, fighting naps, or treating bedtime like a protest, chances are you’re in the middle of a sleep regression phase.

What Not to Do During Sleep Regression?

Sleep regression can make even the most patient parents question everything, but there are a few things you’ll want to avoid. Don’t panic and overhaul your entire routine—consistency is key. Avoid letting an overtired newborn stay up too long, or you’ll be dealing with an even bigger bedtime battle. And while it’s tempting, try not to introduce sleep crutches you don’t want to keep long-term when trying to soothe your fussy baby (looking at you, middle-of-the-night car rides).

Does Sleep Regression End Naturally?

Yes—sleep regression does end naturally. Your baby’s sleep patterns will eventually settle as they adjust to new developmental leaps and routines. It might take a few weeks, but one day, you’ll realize they slept through the night—and you actually miss those extra snuggles.

Sleep regression might test your patience (and your caffeine tolerance), but it’s just a phase—one that will pass with time, consistency, and maybe a few extra snuggles. Keep your routine steady, adjust as needed, and remember: your baby will sleep again.
