What is Baby Sleep Regression?
Sleep regression is a common yet challenging phase that many parents face during their baby's first two years. A sleep regression is when a baby who was previously sleeping well suddenly starts waking up frequently throughout the night, fighting their naps, or having difficulty falling asleep. While frustrating for parents, sleep regressions are actually a sign of your baby's developing brain and body.
In this blog, we discuss what baby sleep regression is, why it happens, and how you can get through it with your baby. Read until the end for some helpful tips!
Why Do Baby Sleep Regressions Happen?
Sleep regressions are typically linked to developmental milestones and changes in a baby’s sleep cycles. As your baby grows and learns new skills, their sleep patterns can be temporarily disrupted. Common causes of sleep regression can range from brain development to changes in routine. Here are the most well-known causes of sleep regressions.
Neurological Development
Around 3-4 months of age, babies experience a significant change in their sleep architecture. Their sleep cycles begin to mature, resembling those of adults with distinct stages of light and deep sleep. This transition can lead to more frequent wake-ups as babies learn to navigate these new sleep patterns.
Physical Milestones
Learning to roll over, sit up, crawl, or walk can excite babies so much that they want to practice these skills even during bedtime. This newfound mobility can make it harder for them to settle down and stay asleep.
Cognitive Leaps
As babies' brains develop, they become more aware of their surroundings and may experience separation anxiety. This increased awareness can make it difficult for them to relax and fall asleep, especially if they realize you're not in the room!
Changes in Routine
Life changes such as starting daycare, moving to a new home, or adjusting to a new sibling can disrupt a baby's sleep patterns. Even positive changes can affect sleep as babies process new experiences.
Common Sleep Regression Phases By Age
While every baby is unique, there are some typical ages when sleep regressions are more likely to occur.
4-Month Sleep Regression
At 4 months, babies often have their first and most significant sleep regression. It's caused by the maturation of sleep cycles and typically occurs between 3-4 months of age. This change is permanent and marks a shift towards more adult-like sleep patterns.
8-10 Month Sleep Regression
Around this age—sometimes ranging from 6 month sleep regression to 10 months—babies are becoming more mobile and more aware of their environment. They might experience separation anxiety from their parents. They also may resist naps or wake frequently at night, calling out for their parents.
12-Month Sleep Regression
As babies approach their first birthday, they may be transitioning from two naps per day to only one, which can temporarily disrupt nighttime sleep. They're also likely developing new cognitive and physical skills that can interfere with sleep.
18-Month Sleep Regression
Toddlers at this age are asserting their independence and may start to resist bedtime and nap time. They might also be experiencing vivid dreams or nightmares for the first time, which can interrupt sound sleep.
24-Month Sleep Regression
The 2-year sleep regression often coincides with major life changes like potty training or moving to a toddler bed. Increased imagination can also lead to nighttime fears such as thinking there are “monsters in the closet” or something scary might happen if they fall asleep.
Signs of Sleep Regression
How can you tell if your baby is experiencing sleep regression? Look out for these common signs:
Increased night wakings
Difficulty falling asleep at bedtime
Fighting naps or taking shorter naps
Increased fussiness or irritability
Changes in appetite
Seeming overtired during the day
You’ll also notice other family members being tired or stressed if your baby keeps waking up in the middle of the night.
How Long Do Sleep Regressions Last?
The good news is that sleep regressions are temporary. Most last between 2-6 weeks, though the exact duration can vary from baby to baby. The 4-month sleep regression is an exception, as it marks a permanent change in sleep patterns rather than a temporary regression.
Managing Your Baby’s Sleep Regressions
While sleep regressions can be challenging, there are strategies you can use to help your baby (and you!) get through them.
Maintain a Consistent Routine
Maintaining a consistent bedtime routine can provide comfort and predictability for your baby, even during sleep regressions. A calming routine might include a warm bath, reading a book, and singing a lullaby.
Create a Sleep-Friendly Environment
Ensure your baby's sleep space is dark, quiet, and at a comfortable temperature. Consider using blackout curtains and a white noise machine to create an optimal sleep environment.
Practice Independent Sleep Skills
Encourage your baby to fall asleep independently by putting them down while they’re drowsy but awake. This helps them develop the ability to self-soothe and fall back asleep on their own when they wake during the night.
Adjust Wake Windows
Pay attention to your baby's sleep cues and adjust their wake windows (time between sleeps) accordingly. An overtired baby will have more trouble falling and staying asleep.
Offer Extra Comfort
During regressions, your baby may need extra reassurance. It's okay to offer additional comfort, but try to avoid creating new sleep associations that might be hard to break later.
Be Patient and Consistent
Remember that sleep regressions are temporary. Stay consistent with your approach, even if it doesn't seem to be working immediately. Consistency helps your baby feel secure and understand what's expected.
Consider Sleep Training
If sleep issues persist beyond the typical regression period, you might consider gentle sleep training methods to help your baby develop healthy sleep habits.
When to Seek Help
While sleep regressions are normal, persistent sleep issues can be exhausting for both babies and parents. If you're concerned about your baby's sleep patterns or if sleep problems are severely impacting your family's well-being, don't hesitate to consult your pediatrician. They can rule out any underlying health issues and provide personalized advice for your situation.
