The 12-month sleep regression is a common yet often unexpected challenge for many parents. Just as you start feeling confident in your little one’s sleep routine, disruptions can occur seemingly out of nowhere. If your baby is suddenly fighting naps, waking frequently overnight, or taking longer to settle, you may be experiencing the 12-month sleep regression. But don’t worry—it’s temporary, and with the right approach, you can support your baby through it.

Why Does the 12-Month Sleep Regression Happen?

Sleep regressions often align with key developmental milestones, and the 12-month mark is no exception. At this age, your baby is experiencing rapid changes in multiple areas, including:

• Increased mobility: Many babies are mastering standing, cruising, or even walking, making sleep seem far less appealing.

•  Separation anxiety: Around this time, your baby may become more aware of when you leave, making it harder for them to settle independently. This tends to peak around developmental leaps including the 8-10 month regression, 12-month regression, 15-18 month regression, and 24-month regression.

• Nap transitions: Some babies start resisting their naps, leading parents to wonder if they’re ready to transition to one nap (spoiler: most aren’t quite ready yet!).

• Cognitive leaps: Language development, problem-solving skills, and curiosity about the world can keep your baby’s mind buzzing at bedtime.

Common Signs of the 12-Month Sleep Regression

Not all babies experience sleep regressions in the same way, but common signs include:

• Increased night waking

• Difficulty settling at bedtime

• Shorter or refused naps

• Early morning wake-ups

• More clinginess and difficulty with separation

How Long Does It Last?

Most sleep regressions, including the 12-month regression, last between 2-4 weeks. However, the duration depends on how you respond to your baby’s sleep disruptions. 

Tips to Navigate the 12-Month Sleep Regression

While sleep regressions can feel overwhelming, there are steps you can take to support your baby and maintain healthy sleep habits:

 Try and stick to your routine as best you can. It's easy to hit struggle town and start compensating for loss of sleep, but this can prolong the process and make sleep feel even trickier.

Depending on their routine, your baby may start resisting either nap. In many cases, the 2-to-1 nap transition happens between 15-18 months, so hold on to that nap until you shift through the regression.

Increased separation anxiety can make sleep times more challenging. Providing plenty of reassurance, cuddles, and one-on-one time during the day can help ease their anxiety at bedtime.

Sleep regressions are temporary! With a consistent approach, your baby will return to more settled sleep soon. Focus on small adjustments and trust the process.

It doesn't last forever!

Thankfully nothing lasts forever, your little one will return to great sleep soon. Be patient, find ways to honor your toddler’s needs and support them as they master their new skills.

Remember, each baby is unique, and what works for one may not work for another. Trust your instincts, and don't hesitate to reach out for support if you need it.
