Sleep regression is a period when a baby or child who was sleeping well suddenly starts sleeping poorly. This can manifest as skipping naps, resisting bedtime, waking up frequently at night, and early morning awakenings. Sleep regression usually lasts for about two to four weeks but can last for up to six weeks in some cases.

What You'll Learn

Sleep regressions typically last for two to four weeks
Sleep regressions are temporary disruptions in a child's sleep patterns, and they can be exhausting for parents and caregivers. They are characterised by the child skipping naps, resisting bedtime, waking up frequently at night, and wanting to start the day before dawn. These regressions are common during times of developmental growth or big transitions, such as starting preschool or the birth of a sibling. While sleep regressions can be challenging, there are strategies to help manage them.
Sleep regressions typically last for about two to four weeks. Maintaining a consistent sleep routine can help shorten their duration. It is important to identify the root cause of the regression and address it. For example, if your child is experiencing separation anxiety, addressing it during the day can reduce its impact on their sleep at night.
- Be mindful of schedule shifts and ensure your child is following an age-appropriate schedule with enough awake time to build sleep pressure.
- Go back to the basics and maintain consistent routines and a soothing sleep environment.
- Check your mindset and avoid getting frustrated or trying to force your child to sleep. Studies show that children mimic their caregivers' emotions, so staying calm and relaxed can help your child settle into sleep more easily.
- Allow time for practicing new skills during the day. This can reduce the need for practice at night when you are trying to sleep.
- Give extra comfort but avoid introducing new sleep crutches. Reassure your child with extra snuggles, but try not to rock them to sleep or nurse them to sleep, as this may prolong the regression.
By understanding the causes and implementing these strategies, you can help your child through sleep regressions and improve their sleep patterns.

They can last longer if you don't address the root cause
Sleep regressions are temporary disruptions in a child's sleep patterns, which can be distressing for parents and caregivers. While they are a normal part of a child's development, they can last longer if the root cause is not addressed.
Sleep regressions can occur at various developmental milestones, such as learning to sit up, crawl, or walk, and are often linked to a desire for independence and separation anxiety. They can also be caused by life changes, such as starting daycare, moving to a new home, or the arrival of a new sibling.
During a sleep regression, children may skip naps, fight sleep, wake up frequently at night, and experience difficulty falling asleep. These changes in sleep patterns can last for two to six weeks, but they can become long-term struggles if consistency is not maintained and healthy sleep routines are not followed.
To address the root cause of a sleep regression, it is important to identify and understand the underlying factors contributing to the disruption. For example, if your child is experiencing separation anxiety, addressing this issue during the day can help reduce its impact on their sleep at night. Similarly, if teething is causing discomfort and leading to frequent night wakings, providing opportunities for your child to relieve their sore gums during the day can help alleviate the issue.
Another factor to consider is the maintenance of a consistent sleep routine. Establishing a bedtime routine that includes calming activities, such as a warm bath, infant massage, reading a book, or singing a song, can help signal to your child that sleep is approaching. Consistency in the sleep environment and bedtime habits can promote better sleep and shorten the duration of sleep regressions.
By addressing the root cause of sleep regressions and implementing healthy sleep habits, you can help your child's sleep patterns return to normal more quickly and prevent long-term struggles. It is important to be patient, consistent, and understanding during these periods of disrupted sleep.

Sleep regressions are common at 4, 6, 8, 12, 18, 24 months
Sleep regressions are common at various stages of a child's development and can be caused by a range of factors. While they can be challenging for parents and caregivers, they are a normal part of a child's growth. Here are some insights into sleep regressions at 4, 6, 8, 12, 18, and 24 months:
4-Month Sleep Regression:
At four months, a baby's brain and body undergo rapid development, which can lead to instability in their sleep patterns. This transition away from the newborn sleep pattern may not always be smooth, resulting in disrupted sleep duration and quality. Signs of a 4-month sleep regression include difficulty falling asleep, frequent night wakings, irritability, and reduced total sleep time. To cope, caregivers should encourage healthy sleep routines and adhere to safe sleep guidelines, such as providing a calm and quiet sleep environment.
6-Month Sleep Regression:
Sleep regressions around six months are often associated with developmental milestones and changing sleep needs. Separation anxiety, teething, and adjustments to sleep patterns can contribute to disrupted sleep. Signs may include night wakings, shorter naps, and fussiness. Consistency and maintaining healthy sleep habits are key to navigating this phase.
8-Month Sleep Regression:
The 8-month sleep regression is characterized by a sudden decline in sleep patterns, with babies resisting sleep and experiencing increased night wakings. This regression is often linked to factors such as growing out of the 3-nap schedule, separation anxiety, and the achievement of new motor skills. To manage this phase, caregivers can offer additional comfort, follow age-appropriate wake windows, and practice new skills during the day to reduce their excitement at bedtime.
12-Month Sleep Regression:
Around their first birthday, some children experience a 12-month sleep regression due to factors such as restlessness, separation anxiety, teething, and adjustments to sleep patterns. Signs include frequent night wakings, difficulty getting back to sleep, agitation, and longer daytime naps. Encouraging healthy sleep habits, maintaining a consistent bedtime routine, and providing active daytime stimulation can help children through this phase.
18-Month Sleep Regression:
The 18-month sleep regression is associated with toddlers seeking independence and testing boundaries. They may refuse to sleep at bedtime, experience increased night wakings, and fight naps. This regression can last for 2-6 weeks, and it's important for parents to offer an age-appropriate bedtime, prioritize naps, and set consistent limits and bedtime routines.
24-Month Sleep Regression (2-Year-Old Sleep Regression):
The 2-year-old sleep regression is often linked to significant developmental milestones and life changes, such as starting school or having a new sibling. Signs include night wakings, early morning wakings, nap struggles, and bedtime resistance. Consistency, introducing comfort objects ("loveys"), and providing stimulating awake time activities can help toddlers through this phase.
While the duration of sleep regressions can vary, they typically last for a few days to several weeks. Maintaining healthy sleep habits, offering comfort, and making gradual adjustments to sleep routines can help children and caregivers navigate these challenging periods.

They are linked to developmental milestones
Sleep regressions are temporary disruptions in a child's sleep patterns. They are characterised by changes such as skipping naps, resisting bedtime, waking up frequently at night, and wanting to start the day before dawn. These disruptions can be frustrating and exhausting for parents and caregivers.
Sleep regressions are linked to developmental milestones and typically occur at 4 months, 6 months, 8 months, 12 months, 18 months, 2 years, and 2.5 years. They are a normal part of a child's development and indicate that they are progressing and learning new skills.
The 4-month sleep regression is often the first and most notorious one. This is when a baby's sleep patterns change permanently from newborn sleep to a more mature progression between sleep stages and cycles throughout the night, similar to older babies, children, and adults. There is a brief waking at the end of each sleep cycle, which happens every hour or so. During these brief arousals, babies check that everything is okay, and if not, they may need extra comfort to fall back asleep.
The 8-month sleep regression is often linked to separation anxiety and the development of object permanence. Babies realise that when a caregiver leaves the room, they haven't disappeared but are somewhere else. This can cause sleep problems, and it's important to maintain a consistent schedule, bedtime routine, and offer extra reassurance.
The 12-month sleep regression coincides with new skills like walking and babbling, as well as weaning off breast milk or infant formula. These big life changes can disrupt sleep patterns.
The 18-month sleep regression is when toddlers start exploring their independence and testing boundaries. They may resist sleep and assert their opinions more strongly.
The 2-year sleep regression can be surprising for parents as it often affects children who were previously sleeping well. It is often linked to big transitions such as potty training, starting school, or the arrival of a new sibling.
While sleep regressions are linked to developmental milestones, not all children experience sleep disturbances during these periods. Each child is unique, and the impact of cognitive and physical development on their sleep will vary.

They can also be caused by teething, illness, travel or routine changes
Sleep regression can be caused by teething, illness, travel, or routine changes. Here's how these factors can impact your baby's sleep:
Teething
The pain and discomfort from teething can keep babies awake and disrupt their sleep patterns. Signs of teething include swollen, tender gums, irritability, increased biting or chewing, new night waking and/or sleep resistance, and a slight increase in temperature. Teething fussiness usually ends between the ages of 2 and 3 years, but the first few months are typically the hardest. To help soothe teething pain, you can try massaging your baby's gums, offering teething toys or cold washcloths to chew on, or giving them frozen foods like bananas or bagels (with supervision).
Illness
Illnesses such as a cold or an ear infection can cause sleep regression in babies. It's important to address any underlying health issues to help your baby get back to a healthy sleep schedule.
Travel
Traveling can disrupt your baby's sleep schedule due to excitement, changes in sleep environment, and shifts in sleep times. To minimize the impact of travel on your baby's sleep, try to stick to their usual sleep schedule as much as possible. When traveling across time zones, gradually adjust your baby's bedtime before and after the trip to minimize disruptions.
Routine Changes
Disruptions in routines, such as starting daycare, can cause sleep regression. Maintaining consistent bedtime routines and healthy sleep habits can help your baby get through these transitions more easily.
Sleep regression caused by these factors typically lasts for a few weeks, but the duration can vary depending on the cause and your baby's individual needs. It's important to be patient, maintain healthy sleep habits, and provide extra comfort to your baby during these challenging periods.
