Your little one is officially a toddler. How did that happen so fast? One moment, they’re smashing their birthday cake and the next, they’re boycotting naps, waking up all night, and demanding extra cuddles at 2 AM.
If you’re suddenly dealing with frequent night-wakings, short naps, and a baby who needs extra love, you’ve likely entered the 12-month sleep regression—a phase that can leave even the most well-rested parents feeling like zombies.
But here’s the good news. This won’t last forever. Your baby isn’t trying to make you miserable (even though it feels that way at 3 AM). They’re simply going through huge developmental changes that temporarily disrupt sleep.
So, why does this happen? How long will it last? And most importantly, how do you survive it? Let’s dive in!
Here in this blog, we’ll cover everything you need to know about the 12-month sleep regression, including its causes, symptoms, and helpful tips to manage it. Plus, we’ll offer insight on when to seek professional help and how to get your little one back to restful sleep.:
The 12-month sleep regression is when a previously good sleeper suddenly starts waking up frequently at night, resisting naps, or taking much shorter naps than usual. You may find bedtime turning into a battle. Your baby, who once fell asleep independently, now refuses to sleep without extra comfort.

Your baby is hitting major developmental milestones, which can temporarily throw off their sleep. Some common signs include:
✔️ Frequent night wakings – Your baby wakes multiple times and may have trouble settling back down.
✔️ Nap refusals or shorter naps – Suddenly, naps are a struggle, or they only last 20-30 minutes.
✔️ Trouble falling asleep – Bedtime used to be easy, but now your baby fights sleep like a mini warrior.
✔️ Increased restlessness and closeness – They want to be held all day and night, and separation anxiety may be at its peak.
✔️ More energy at bedtime – Instead of winding down, they’re standing in the crib, clapping, or practicing new skills.
If this sounds familiar, you’re not alone! The length of a sleep regression can vary depending on your baby’s age and developmental stage, but the 12-month sleep regression often lasts around 2 weeks or even less[1]. With the right strategies, you’ll help your little one get back on track soon!

This sleep disruption isn’t random; a lot is going on in your baby’s little world! Here’s what’s causing those sudden sleepless nights:
Your baby’s brain is buzzing with new skills and endless curiosity:
With so much happening, it’s no wonder their brain won’t shut off at night!
Ever tried to sneak out of your baby’s room like a ninja, only for them to wake up immediately? That’s separation anxiety in action.
At this age, babies begin developing object permanence[2], the understanding that you still exist even when they can’t see you. This cognitive leap makes it more difficult for them to handle separations, as they now realize you're around even though they can’t see you. This heightened awareness can lead to:
Friendly reminder: Your baby isn’t manipulating you. This is a normal part of development, and extra reassurance helps them feel secure.
If your baby is crawling, pulling up, cruising, or even taking first steps, their body is restless, and they may practice these new skills in their crib instead of sleeping.
Ever walked in on your baby standing up in the crib, grinning at you? That’s because their body is telling them, “Let’s practice standing instead of sleeping!”
At 12 months, some babies start fighting their second nap, even if they still need it. The result?
So, what can you do to survive this phase? Let’s get into some practical tips.
While you can’t stop the regression, you can ease the transition with these tried-and-true strategies:

While most sleep regressions resolve on their own, when should you consider professional help? Let’s discuss.
Most babies move through sleep regressions on their own, but sometimes, extra support is needed. Consider speaking with a pediatrician or sleep consultant if:
The 12-month sleep regression can feel exhausting, but you’re not alone! This phase is completely normal, even if it doesn’t feel that way at 3 AM. Your little one is growing in big ways cognitively, emotionally, and physically, which can shake up their sleep. More night wakings, nap resistance, and extra clinginess? Yep, all part of the package.
The good news? This won’t last forever, typically 2 to 6 weeks. Stick to a comforting routine, offer reassurance without introducing new habits, and let them burn off energy during the day. With a little patience and a lot of coffee, you’ve got this!
