Why Does Infant Sleep Regression Happen and How to Handle It

Sleep regression can be tough, especially when your infant won't sleep​, but it’s completely normal. It happens when your baby grows and learns new things. For example, skills like rolling over or crawling make their brain busier. This can make it harder for them to sleep well.

About 10% of babies have trouble sleeping and wake up often. Research shows that when your infant won't sleep​, it might mean slower development. But these sleep problems don’t last forever. Knowing why your baby isn’t sleeping can help you handle it better. It also helps your baby grow and learn.

Key Takeaways

• Sleep regression is normal and happens as babies grow and learn.

• It often occurs at 4, 6, 8, 12, 18, and 24 months during big growth stages.

• A steady bedtime routine helps babies feel safe and adjust better.

• Things like teething, sickness, or growth spurts can disturb sleep but won’t last forever.

• A cozy sleep space with dark curtains and soft sounds helps babies sleep well.

• Teaching babies to calm themselves helps them fall back asleep alone at night.

• Stay patient and calm; sleep regression is just a phase that will end.

• Take care of yourself and ask family or friends for help if you’re tired.

What Is Sleep Regression?

Definition and Overview

Sleep regression is when your baby’s sleep changes for a while. They may wake up more at night or struggle to fall asleep. This often happens during times of fast growth or learning new skills. For example, your baby might wake up more when learning to roll over or sit. Even though it’s hard, sleep regression is a normal part of growing up.

During this phase, your baby’s brain works harder to process new skills. This extra brain activity can mess up their usual sleep schedule. It might feel stressful, but knowing why it happens can help you handle it better.

Why Sleep Regression Is a Normal Developmental Phase

Sleep regression shows that your baby is growing and learning. Studies say waking up at night is common and doesn’t harm growth. Over half of 12-month-old babies wake up at night, says Scher. Another study by Paavonen et al. found 28.4% of 2-year-olds still wake often. These studies prove sleep regression is a natural part of growing up.

Your baby’s brain changes a lot during these times. They might be learning to crawl, walk, or talk. These big milestones take energy and can disturb sleep. It can be tough, but these changes are important for your baby’s growth.

Common Ages for Sleep Regression (Including 4 Month Sleep Regression)

Sleep regression happens at certain ages in your baby’s life. The 4 month sleep regression is one of the most common stages. At this time, your baby’s sleep becomes more like an adult’s. This can cause shorter naps and more night waking.

Other common ages for sleep regression are 6, 8, 12, 18, and 24 months. Each stage matches a big milestone or change in routine. For example, the 6-month stage might happen with teething. The 12-month stage often happens when babies start walking.

Here’s a table showing common ages for sleep regression:

Knowing these stages can help you get ready for them. For example, understanding the 4 month sleep regression is normal can make sleepless nights easier to manage.

Why Infant Sleep Regression Happens

Developmental Milestones and Brain Growth

Your baby’s brain grows quickly in the early years. This fast growth often causes sleep regression. When babies learn skills like crawling or sitting, their brain works harder. This can mess up their sleep schedule. A study from the University of Washington found that sleep problems in babies are linked to changes in the hippocampus. The hippocampus is the brain part that helps with memory and learning. These changes show how sleep and brain growth are connected.

During these milestones, your baby’s brain is busy learning new things. This can make it harder for them to relax at night. You might notice shorter naps or more waking at night. These sleep troubles are temporary and mean your baby is growing.

Changes in Routine and Environment

Big changes in your baby’s life can also cause sleep regression. Moving to a new house, starting daycare, or going on vacation can make them feel unsettled. Babies like routines, so any change can affect their sleep.

You can help by keeping bedtime routines the same. A warm bath, a story, or a lullaby can help them relax. These familiar steps tell your baby it’s time to sleep, even if their day was different.

Tip: If a routine change causes sleep problems, go back to their usual schedule quickly. Keeping things consistent helps them feel safe.

Emotional Growth and Anxiety

As babies grow emotionally, they may feel separation anxiety. This often peaks around 18 months and can make sleeping alone hard. They might cry when you leave or wake up needing comfort. Emotional growth is normal but can disturb sleep for a while.

Studies show separation anxiety can lead to later bedtimes and less sleep. One study of 117 mother-child pairs found that emotional growth affects sleep patterns. Babies with more separation anxiety often had worse sleep.

To help, spend extra time with your baby before bed. A calm bedtime routine can make them feel safe. Remember, this phase is short and shows your baby is growing emotionally.

Physical Reasons: Teething, Sickness, and Growth Spurts

Physical reasons like teething, sickness, and growth spurts can cause sleep regression. These changes in your baby’s body may disturb their usual sleep, making it harder for them to rest well.

Teething and Sleep Problems

Teething often causes sleep regression. When babies start teething, their gums may swell, and they might drool more. This can make them uncomfortable and harder to settle at night. You may notice your baby waking up more or being fussier at bedtime. To help, try using a cold teething ring or gently massaging their gums. Keeping their bedtime routine steady can also comfort them during this tough time.

Sickness and Sleep Changes

Sickness, like colds or ear infections, can also lead to sleep regression. When babies feel sick, symptoms like fever or stuffy noses can make sleeping difficult. They may wake up more often or need extra cuddles to feel better. A quiet, calm space can help them rest. Once they recover, their sleep usually goes back to normal.

Growth Spurts and Hunger

Growth spurts are another reason for sleep regression. During these times, babies grow quickly and may feel hungrier. This can cause them to wake up more at night for extra feedings. You might also see them eating more during the day. These changes are short-term and show healthy growth. Offering extra food and ensuring they’re full can help during this phase.

Here’s a simple table showing how these physical reasons affect sleep:

Tip: If your baby’s sleep regression is due to physical reasons, focus on comforting them. These phases are normal and will pass as they grow.

By knowing how teething, sickness, and growth spurts affect sleep, you can better help your baby. These sleep troubles are normal and show your baby is growing and developing.

Signs Your Baby May Not Sleep Well Due to Sleep Regression

Waking Up Often at Night

Waking up many times at night is a common sign. Your baby might wake up and have trouble going back to sleep. This can happen because their brain is learning new things or they feel uncomfortable, like from teething. They may cry or fuss more during these wake-ups, needing comfort.

Some behaviors you might see include:

• Not wanting to go to bed.

• Trouble falling asleep quickly.

• Waking up often and staying awake longer.

• Crying or being fussy during the night.

To help, keep bedtime routines steady. Calm activities like reading or singing can show it’s time to sleep. Comfort your baby without starting habits like rocking or feeding them to sleep.

Trouble Falling Asleep

Another sign of sleep regression is having a hard time falling asleep. Your baby might take longer to settle down, even if they seem tired. This happens because their brain is busy learning or dealing with emotions.

You might notice your baby getting restless or upset at bedtime. They could cry or resist being put in their crib. This can be frustrating, but it’s a normal part of growing up.

To help, make the room calm and quiet. Lower the lights, reduce noise, and keep the room cozy. A regular bedtime routine can also help your baby relax and get ready for sleep.

Shorter Naps or Skipping Naps

Sleep regression can also affect naps during the day. Your baby’s naps might get shorter, or they may refuse to nap at all. This can make them overtired, leading to more night wakings and fussiness.

Signs of nap problems include:

• Naps that are shorter than usual.

• Refusing to nap, even when they seem tired.

• Crying or fussing when it’s time to nap.

• Sitting or standing in the crib instead of lying down.

If your baby used to nap well but suddenly doesn’t, sleep regression might be the reason. Stick to a regular nap schedule and watch for signs they’re tired, like yawning or rubbing their eyes. A quiet, dark space can also help them nap better.

These sleep changes won’t last forever. By staying calm and consistent, you can help your baby get through this phase and sleep better again.

More Fussiness and Wanting to Be Held

During sleep regression, your baby might act fussier and want to be held more. This happens because they are going through emotional and physical changes. They may cry often, need extra attention, or not want to be put down. While this can feel hard, it’s a normal part of their growth.

Fussiness gets worse when your baby is tired but can’t sleep. Their brain is busy learning new things, making it harder to relax. You might also notice them holding onto you more for comfort. This clingy behavior is common, especially during separation anxiety, which peaks around 18 months.

Here’s how you can help:

• Give extra hugs: Hold or cuddle them when they seem upset. This helps them feel safe.

• Stick to routines: Keep bedtime routines the same to create stability.

• Stay calm: Remember, this phase is short and shows emotional growth.

Note: Fussiness and clinginess are normal signs of sleep regression. These behaviors show your baby is adjusting to changes in their body and surroundings.

Feeding and Eating Changes

Sleep regression can also change how your baby eats. You might see them eating more, eating less, or eating at odd times. These changes happen because growth spurts and milestones need extra energy.

During growth spurts, babies may wake up more at night to eat. Their body needs more food to grow. But teething or being sick can make them eat less during the day. These shifts can mess up their usual eating schedule and affect sleep.

Here’s how to handle feeding changes:

1. Watch for hunger signs: Offer food or milk when they seem hungry.

2. Change feeding times: If they eat less during the day, they might need more food at night.

3. Keep mealtimes steady: A calm and regular routine helps them feel secure.

Tip: If feeding changes last too long or seem unusual, talk to your doctor to check for other issues.

By understanding these changes, you can support your baby through sleep regression. Their eating and sleeping will settle as they grow and adjust.

How Long Does Sleep Regression Last?

Usual Length of Sleep Regression Periods

Sleep regression doesn’t last forever, but its length can differ. Most sleep regression periods last about two to six weeks. During this time, your baby might wake up more, nap less, or have trouble sleeping. These changes happen because their brain is learning new things or their body is growing.

The four-month sleep regression is different. It’s a lasting change in how your baby sleeps. At this stage, their sleep cycles become more like an adult’s, with light and deep phases. Until they learn to calm themselves, they may wake up more often. This phase can be hard, but it’s a big step in their growth.

Other sleep regression stages, like at six or twelve months, are usually shorter. These often happen with milestones like crawling, walking, or teething. While these stages can disturb sleep, they show your baby is growing well.

What Affects How Long Sleep Regression Lasts

Different things can change how long sleep regression lasts. Knowing these can help you handle this phase better. Here’s a simple table:

Teething or sickness causes short-term sleep problems. Once your baby feels better, their sleep improves. Learning new skills, like sitting or crawling, can take a few weeks. These changes make their brain work harder, which can affect sleep.

Your baby’s age also matters. Younger babies may have longer sleep disruptions as they adjust to new patterns. For example, the four-month sleep regression is a lasting change. Until they learn to self-soothe, they may wake more often.

To help your baby, keep bedtime routines steady. A calm and predictable schedule can make this phase easier. Remember, sleep regression is temporary, and your baby will sleep better soon.

How to Handle Sleep Regression

Keeping a Steady Bedtime Routine

Having the same bedtime routine every night helps a lot. Studies show routines can lead to earlier bedtimes and better sleep. They also help your baby’s brain and emotions grow.

Create a simple plan for bedtime. You could give your baby a warm bath, read a short book, or sing a lullaby. These steps tell your baby it’s time to relax. Keep the routine short, about 20-30 minutes, and do it at the same time each night. This makes your baby feel safe and helps them fall asleep on their own.

If your baby fights bedtime, stay calm and stick to the plan. Even on hard nights, being consistent will help them adjust and sleep better over time.

Making the Sleep Space Comfortable

Your baby’s room should be cozy and safe to help them sleep. Research shows a good sleep space makes it easier for babies to relax and sleep alone.

Here are some tips for a better sleep environment:

• Use blackout curtains to keep the room dark.

• Keep the room temperature between 68-72°F (20-22°C).

• Play soft white noise or lullabies to block other sounds.

• Dress your baby in light, breathable clothes.

• Make sure the crib has a firm mattress and no loose items.

These changes can help your baby feel more comfortable and less distracted. A steady sleep environment also supports the bedtime routine, making it easier for your baby to settle down.

Teaching Self-Soothing Skills

Helping your baby learn to calm themselves is important during sleep regression. Self-soothing lets them fall back asleep without needing you every time.

For newborns, start by building good sleep habits early. Put them in their crib when they’re sleepy but still awake. This helps them connect the crib with falling asleep. Use calming methods like swaddling, rocking, or soft shushing sounds. Don’t let daytime naps last longer than three hours, so they’re ready for bed at night.

For older babies, give them a moment to settle before stepping in when they wake up. You can gently rub their back or speak softly without picking them up. If they’re old enough, offer a small blanket or stuffed toy for comfort.

Here’s a table of self-soothing tips by age:

These steps take time, but they can help your baby learn to sleep on their own and manage sleep regression better.

Adjusting Daytime Schedules and Naps

Changing your baby's daytime routine can ease sleep regression. Babies do best with regular schedules. A good nap schedule helps prevent overtiredness, which often causes more night waking.

Here’s how to create a better daytime routine:

1. Stick to regular naps: Plan for 2-3 naps daily, based on your baby’s age. Proper naps stop overtiredness, making nighttime sleep easier.

2. Set a steady routine: Do calming things like a warm bath or rocking before naps. These activities show your baby it’s time to rest.

3. Adjust nap times slowly: If changes like daylight saving time affect sleep, shift naps and bedtime by 10-15 minutes daily over 3-4 days. This gradual change helps them adjust better.

To prepare for the fall time change, start shifting your baby’s sleep schedule early. Move bedtime and wake times 10-15 minutes later each day for 3-4 days. This slow adjustment makes the transition smoother.

By keeping naps regular and adjusting schedules carefully, your baby will feel more rested and ready for nighttime sleep.

Staying Calm and Responding to Night Wakings

Night wakings are normal during sleep regression. Your baby may wake more often as they grow and learn. Staying calm and responding wisely can help them settle faster.

Try these tips when your baby wakes at night:

• Give them a moment: Babies often stir between sleep cycles. Waiting a bit lets them self-soothe and fall back asleep.

• Avoid too much stimulation: Don’t pick them up right away or turn on bright lights. Use a soft voice and gentle touch to comfort them without fully waking them.

• Keep it short: If they need attention, keep it quick and calm. Avoid playing or long cuddles, as this can make it harder for them to sleep again.

Experts suggest letting babies adjust naturally between sleep cycles. This builds their self-soothing skills and helps them sleep better. Picking them up too quickly can disrupt their sleep and lead to more daytime tiredness.

By staying calm and consistent, you can help your baby handle night wakings better. Remember, this phase is temporary, and your baby will soon sleep more peacefully again.

Tips for Parents to Manage Sleep Deprivation

Prioritizing Rest and Self-Care

Taking care of yourself is very important when you're tired. Your baby needs you to feel rested and calm. Getting enough rest helps you handle challenges better and support your baby's growth. Studies show that good sleep helps a baby's brain grow by organizing new information. When you focus on your rest, you create a better space for your baby to grow.

Here are some ways to manage being tired:

• Take short naps during the day, even just 20 minutes. These can help you feel refreshed without making you groggy.

• Delay non-important tasks like cleaning or visiting friends. Use that time to rest instead.

• Make your bedroom cozy by keeping it dark, quiet, and comfortable.

Remember, taking care of your rest helps both you and your baby. A rested parent can give better care and attention to their child.

Asking for Help from Family or Friends

You don’t have to handle being tired all by yourself. Asking family or friends for help can make things easier. A good support system can lower stress and help you feel stronger. For example, family members can help with bedtime routines or watch your baby so you can rest. This gives you time to recharge and be more patient.

Getting help also reduces anxiety and sadness caused by lack of sleep. Research shows rested parents bond better with their babies. Don’t be afraid to ask loved ones for help. They can take turns feeding the baby at night or watching them during the day. Every little bit of help makes a difference.

Tip: Make a schedule with your partner or family to share tasks. This way, everyone gets some rest while caring for the baby.

Practicing Patience and Understanding

Sleep regression doesn’t last forever, but it can feel hard. Being patient and understanding can help you get through it. Remember, your baby’s sleep changes mean they are growing and learning. They are adjusting to new skills, which can affect their sleep for a while.

If you feel upset, take a deep breath and pause. Remind yourself that this phase will pass. Staying calm and keeping your baby’s routine steady can really help. If it feels too hard, ask for help or talk to a doctor for advice.

By staying patient, you create a positive space for you and your baby. This helps you manage tiredness while supporting your baby’s growth and learning.

Remembering That Sleep Regression Won’t Last Forever

Sleep regression can feel tough, but it’s only temporary. Your baby’s sleep will get better as they grow and reach new milestones. Keeping this in mind can help you stay calm during sleepless nights.

Why Sleep Regression Doesn’t Last

Sleep regression happens because your baby is growing quickly. These changes can disturb their sleep, but they show healthy development. For example, learning to crawl or talk makes their brain more active. This can make it harder for them to relax at night. Once they learn these skills, their sleep usually improves.

Tip: Think of sleep regression as progress. It shows your baby is learning and growing, even if it feels hard now.

Staying Positive Through This Phase

It’s normal to feel upset when your baby wakes up often. But staying positive can help both you and your baby. Here are some ways to keep a good attitude:

• Think About the Big Picture: Sleep regression is a normal part of growing up. It doesn’t mean you’re doing anything wrong.

• Celebrate Small Wins: Notice your baby’s milestones, like rolling over or saying words. These moments show the sleepless nights are worth it.

• Take Breaks When Needed: If you’re feeling tired, ask someone to help at night. A short break can boost your energy and mood.

Note: Babies can sense your feelings. Staying calm and positive helps them feel safe, which might improve their sleep.

What’s Ahead

As your baby grows, their sleep will become more regular. They’ll sleep longer at night and need fewer naps during the day. This will give you more time to rest. Knowing better sleep is coming can keep you motivated.

Reminder: Every baby is different. Some may outgrow sleep regression fast, while others take longer. Be patient and trust the process.

By staying positive and remembering that sleep regression is temporary, you can handle this phase with confidence. You’re not alone, and this challenging time will pass soon.

Sleep regression is a normal part of growing up. It often happens when babies learn big skills like crawling or walking. These times can be hard, but they don’t last forever. With the right steps, you can help your baby through it.

Being patient and keeping routines steady is important. Don’t forget to care for yourself, too. This phase will end, and you’re not alone in this! 😊
