Baby Sleep Regressions: Helping Your Baby Through the 18-Month Sleep Regression

Baby sleep regressions are developmental stages where infants struggle with sleep. Typically, these phases can occur at 4, 6, 8, 12, and 18 months, and also around 2 years of age.

What are baby sleep regressions?

As a parent, few things are as puzzling as when your well-sleeping baby starts waking up at night. They are fussy and unable to settle back down. Welcome to the mysterious world of baby sleep regressions. Understanding these regressions is crucial. They help you navigate the challenges they bring and help your little one (and you)!) get back to dreamland. Let’s dive into ‘What are Baby Sleep Regressions?’ and explore why these sleep disruptions happen.

Key Developmental Milestones

Babies grow rapidly, both physically and mentally. Certain growth spurs, known as developmental milestones, can affect their sleep patterns. Here are some milestones that might lead to sleep regressions:

  • Rolling over
  • Crawling
  • Standing
  • First words
  • Teething

During these times, your baby’s brain and body are too busy mastering these new skills to settle down easily.

Definition Of Sleep Regressions

Simply put, a sleep regression is a period when a baby who has been sleeping well suddenly starts waking up at night, skipping naps, or having trouble falling asleep. It’s like they forgot how to sleep! This change can last from a few days to a few weeks. Let’s break down what this means:

Age Common Sleep Regression Stage
4 months Adjusting to changing sleep cycles
8 months Struggling with separation anxiety and new physical skills
12 months Experiencing developmental leaps and teething
18 months Battling newfound independence and language acquisition
2 years Dealing with big kid bed transition and vivid imaginations

In essence, sleep regressions are a sign that your baby is developing normally, even though they can disrupt sleep patterns temporarily.

Causes Of Baby Sleep Regressions

Causes of baby sleep regressions often puzzle and frustrate parents. A baby’s sleep pattern may change suddenly and unpredictably. Understanding these changes is vital to helping your baby get back to snoozing soundly. Let’s explore some common factors behind these sleep disturbances.

Growth And Development

Babies grow and learn new skills quickly. These bursts of growth and development can disrupt sleep. As babies learn to roll, crawl, or walk, their desire to practice these skills can lead to wakefulness.

Separation Anxiety

Typically starting around 6–8 months of age, separation anxiety can shake a baby’s nighttime routine. Their new awareness of being away from their parents can make it tough for them to stay asleep.

Teething And Discomfort

  • Pain from teething can wake babies frequently.
  • Look for signs like drooling, gnawing, and crankiness.
  • Comfort measures may include cold teething rings or gentle gum massages.

Environmental Changes

Changes in a baby’s sleep environment can lead to sleep regression. This might include a new crib, traveling, or even shifts in weather. Consistency helps babies feel secure and sleep better.

Signs Of Baby Sleep Regressions

Welcome to the maze of parenthood, where baby sleep regressions can be a tricky puzzle to solve. Like a stealthy ninja, sleep regression creeps in just when you think bedtime routines are set in stone. This sudden change can be baffling for new parents. Recognizing the signs early can help navigate this phase with more ease. Let’s look at some telltale signs your baby might be going through a sleep regression.

Waking Up Frequently At Night

Nighttime should be peaceful and restful, but during sleep regressions, it’s anything but. It’s common for babies to wake up more often than usual. They may seem upset or need more cuddles to fall back asleep. If your little one, who used to sleep soundly, is now waking up several times, this could be a sign of sleep regression.

Difficulty Falling Asleep

Sleepy cues may no longer do the trick. Babies struggling to drift off can fuss or cry, even if they’re usually good at self-soothing. If your baby is suddenly fighting sleep, it might not just be a one-off—it could signal a regression.

Shortened Nap Duration

Naps are essential for your baby’s growth and your sanity. During sleep regressions, naps may suddenly become shorter, or your baby may skip them entirely. If those precious daytime snoozes shrink or disappear, it’s often a hallmark of sleep regression.

Understanding these signs can help parents prepare for the sleep regression phase. Stay tuned for tips on how to deal with these sleep hurdles.

Tips To Manage Baby Sleep Regressions

Handling baby sleep regressions tests parental patience. Babies often experience changes in their sleep patterns. These shifts can disrupt a household. Effective strategies can ease this phase. Let’s explore ways to encourage better sleep.

Stick to a Consistent Bedtime Routine

Stick To A Consistent Bedtime Routine

Consistency is key. Establish clear bedtime habits. A routine signals that it’s time to sleep. Start with a bath, followed by a book. Soft music or white noise can also help. Keep bedtime at the same hour each night.

Provide comfort and solace.

Provide Comfort And solace.

During regressions, babies seek extra comfort. Offer cuddles. Gentle rocking or back-patting can calm them. A favorite toy or blanket provides additional reassurance. Remember, the goal is to soothe, not to start new habits that could be hard to break.

Create a Sleep-Friendly Environment

Create A Sleep-friendly Environment

The sleep setting matters. Ensure the room is quiet and dark. Consider blackout curtains. The temperature should be cool, between 68 and 72 degrees Fahrenheit. A clutter-free space can promote a more peaceful sleep.

Avoid Reinforcing Negative Sleep Associations

Avoid Reinforcing Negative Sleep Associations

Be cautious with sleep associations. Avoid actions that babies might need every night. This includes rocking to sleep or feeding until they doze off. Instead, lay the baby down, drowsy but awake. They’ll learn to self-soothe without your help.

When To Seek Professional Help

Knowing when to seek professional help can be the key to ensuring your baby’s health and well-being. While temporary changes in sleep patterns are expected as your baby develops, there are instances where these could indicate deeper issues. Understanding when to reach out to a healthcare provider is vital for any concerned parent navigating baby sleep regressions.

Persistent Sleep Problems

If your baby’s sleep struggles seem endless, it might be time to consult a professional. Look out for these signs:

  • Multiple night wakings
  • Difficulty falling or staying asleep
  • Consistent trouble despite routine adjustments

Sleep specialists or your pediatrician can provide guidance when regular sleep strategies don’t yield results.

Failure To Thrive

Proper rest affects overall growth. Signs that require attention include:

  1. Lack of weight gain
  2. Feeding difficulties
  3. Disinterest in interaction

These symptoms can be various, yet attention from a healthcare provider can offer crucial support.

Excessive Daytime Sleepiness

An excessively sleepy baby during the day could indicate sleep quality issues at night. Note the following:

Sign Action
Difficulty waking up for feeds Keep a sleep log and consult your doctor
Little interest in play Discuss sleep patterns with your pediatrician

Alertness during the day is as important as nighttime sleep.

What causes baby sleep regressions?

Babies might have sleep regressions due to milestones or growth spurts. They might also have them due to changes in routine. As babies grow, their sleep patterns may change, causing temporary disruptions. These disruptions are normal.

How long do sleep regressions last?

Sleep regressions can vary in duration, generally lasting from a few days to a few weeks. The length and impact of a regression depend largely on the individual baby, as well as how parents respond to the changes in sleep patterns.

Can sleep training help during regressions?

Sleep training can be helpful during regressions, as it encourages healthy sleep habits. However, patience and flexibility are key as babies work through these developmental phases. Consistency with sleep routines can aid in minimizing regression duration.

When do most sleep regressions occur?

Most sleep regressions occur at predictable ages: around 4 months, 8 months, and 18 months. However, not all babies will experience sleep regressions at these exact times, as individual differences in development play a large role.


Navigating baby sleep regressions can feel overwhelming. Yet, armed with understanding and patience, you’ll smooth out this bumpy phase. Stick to consistent routines and seek support when needed.
