Sleep regression is when a baby who used to sleep well suddenly starts waking up at night, refusing naps, or having trouble falling asleep. It can be frustrating and exhausting, but it’s a normal part of your baby’s development. Let’s break down what sleep regression is, why it happens, and how you can handle it.

What Is Sleep Regression?

Sleep regression is a temporary phase—usually lasting 2-6 weeks—where a baby who was sleeping well suddenly starts having trouble. This often happens because your baby is going through a developmental milestone, like learning to crawl or walk, or a growth spurt.

What Is Not Sleep Regression?

  • Illness: If your baby is sick, teething, or experiencing discomfort, their sleep might be disturbed, but this is different from regression. Once they feel better, their sleep usually returns to normal.
  • Hunger: If your baby is waking up frequently at night because they’re hungry, especially during growth spurts, this isn’t sleep regression. It’s a natural response to needing more food.
  • Developmental leaps without sleep disruption: Not all developmental milestones lead to sleep regression. Sometimes, babies will hit milestones without any noticeable change in their sleep.
  • Inconsistent routine: If your baby’s sleep patterns change due to a lack of routine, irregular bedtimes, or environmental changes, this is not sleep regression but rather a response to the inconsistency.
  • Sleep training: If you’re in the process of sleep training, temporary disruptions in sleep can happen as your baby adjusts, but this is part of the training process, not a sleep regression.

When Does Sleep Regression Happen?

There are a few common ages when sleep regression tends to happen:

  • 4 Months: The first big sleep regression often happens around this time. Your baby’s sleep cycle starts to change, becoming more like an adult’s, which can cause more frequent wakings.
  • 8-10 Months: As babies learn to crawl, stand, and maybe even take their first steps, their sleep can get disrupted. Separation anxiety might also kick in around this age.
  • 12 Months: Around their first birthday, babies might experience another regression as they start walking and transitioning to fewer naps.
  • 18 Months: Teething, increased independence, and maybe a bit of defiance can all contribute to sleep disruptions around this age.
  • 2 Years: Language development and awareness of their surroundings can lead to bedtime battles and more nighttime waking.

How Long Does Sleep Regression Last?

Most sleep regressions last between 2 and 6 weeks. However, the duration can vary depending on the baby and how the situation is managed. During this time, it’s essential to remain consistent with your baby’s sleep routine and be patient as they work through this developmental phase.

5 Common Signs Of Sleep Regression

How do you know if your baby is going through a sleep regression? Here are some common signs:

  1. Waking up more at night: If your baby used to sleep through the night and is now waking up frequently, it could be a sleep regression.
  2. Shorter naps: Suddenly, those long naps turn into quick catnaps, or your baby refuses to nap at all.
  3. Increased fussiness: Your baby might become clingier, more irritable, and harder to soothe, especially when it’s time to sleep.
  4. Difficulty falling asleep: Bedtime might turn into a struggle, with your baby resisting sleep and taking longer to settle down.
  5. Changes in appetite: Some babies eat more or less during a regression, which can also mess with their sleep.

6 Main Causes Of Sleep Regression

Sleep regression is often linked to a few key factors:

  1. Developmental milestones: As babies grow and learn new skills, their sleep can be disrupted. Their brains are busy processing new information and abilities, which can make it harder for them to settle down and sleep.
  2. Growth spurts: During growth spurts, babies might wake up more frequently to feed, as they need more nutrients to support their rapid development. This increased hunger can interfere with their usual sleep patterns.
  3. Changes in environment: Babies are sensitive to changes in their surroundings. Moving to a new home, starting daycare, or even minor changes in their routine can trigger regression.
  4. Teething: The discomfort from teething can disrupt a baby’s sleep, making it harder for them to fall asleep or causing them to wake up more often at night.
  5. Overstimulation: Babies who are overstimulated during the day, whether from too much screen time, noisy environments, or overly active play, may find it difficult to wind down and sleep, leading to disruptions at night.
  6. Transitioning from co-Sleeping to crib Sleeping: Moving your baby from co-sleeping to a crib can be a significant change in their sleep environment. This might lead to temporary disruptions as they adjust to sleeping independently in a different space.

6 Best Strategies To Handle Sleep Regression

While regression can be challenging, there are strategies you can use to help your baby—and yourself—get through it:

  1. Stick to a bedtime routine: Keeping a consistent bedtime routine can help your baby know it’s time to wind down and sleep. This could include a warm bath, reading a book, singing a lullaby, or gentle rocking.
  2. Comforting your baby without creating new habits: It’s important to comfort your baby during sleep regression, but try not to create new sleep habits that might be hard to break later. For example, try patting your baby’s back or offering a pacifier instead of picking them up right away.
  3. Adjust nap times and bedtime: Sometimes, tweaking nap times or bedtime can make a big difference. If your baby is too tired or not tired enough, it can mess with their sleep.
  4. Feeding and sleep regression: During sleep regression, babies might wake up more often to feed. While it’s important to respond to their hunger, you might want to gradually reduce nighttime feedings if you think your baby is ready.
  5. Encourage daytime activity: Ensuring your baby gets plenty of physical activity during the day can help them feel more tired and ready for sleep at night. Engaging in tummy time, crawling, or playing outside can help burn off extra energy.
  6. Limit screen time before bed: Reducing exposure to screens, like TVs, tablets, or smartphones, before bedtime can help prevent overstimulation. The blue light from screens can interfere with the production of melatonin, the hormone that helps regulate sleep.

When To Seek Help

While most sleep regressions resolve on their own, there are times when you might need to seek help. If your baby’s sleep doesn’t improve after several weeks, it could be a good idea to talk to a pediatrician or sleep consultant. Also, if your baby seems unusually fussy or uncomfortable, it’s worth checking with your doctor to rule out any underlying issues like teething or illness. And remember, if you’re feeling overwhelmed or exhausted, don’t hesitate to ask for help. Sometimes, talking to a professional can make a big difference and provide the support you need.

How To Prevent Future Regressions In Babies

While you can’t completely prevent sleep regressions, there are steps you can take to minimize their impact. Consistency is key—maintain a regular sleep routine and keep your baby’s environment as stable as possible. Encouraging independent sleep by gradually teaching your baby to fall asleep on their own can also help them self-soothe during future regressions. Additionally, being aware of upcoming milestones or changes in your baby’s life and planning ahead can make these transitions smoother and less disruptive to their sleep.

Common Myths About Sleep Regression

There’s a lot of advice out there about sleep regression, but not all of it is accurate. Let’s clear up some common myths:

  • “Sleep Regression Lasts Forever”: Regression is temporary and usually resolves within a few weeks.
  • “You Should Let Your Baby Cry It Out During Regression”: While some parents choose this method, there are other ways to comfort your baby without letting them cry for extended periods.
  • “Sleep Regression Means Something Is Wrong”: Regression is a normal part of your baby’s development and doesn’t usually indicate a problem.

Final Thoughts

Sleep regression can be challenging, but it’s a normal part of your baby’s growth. By understanding what’s happening and using some simple strategies, you can help your baby—and yourself—get through this phase. Remember, sleep regression is temporary, and your baby’s sleep will likely improve soon.
