Sleep regression is a term that strikes fear into the hearts of many parents, especially those who have finally found a rhythm with their toddler’s sleep patterns. Just when you thought you had conquered the challenges of newborn sleep, your toddler’s sleep suddenly seems to regress, leaving you feeling exhausted, frustrated, and wondering what went wrong.

But fear not—sleep regression is a normal and temporary phase in a toddler’s development. Understanding sleep regression, why it happens, and how to cope can help ease the stress and confusion often accompanying this challenging period.

What is Toddler Sleep Regression?

Toddler sleep regression is a period of disrupted sleep patterns or difficulties in falling or staying asleep in toddlers who previously had established sleep routines. During sleep regression, toddlers may experience frequent night wakings, difficulty settling down at bedtime, shortened naps, or overall restlessness during sleep. 

Study says approximately 20–30% of children experience night wakings and sleep difficulties during the first two years of their lives.

Sleep regressions indicate that your toddler is going through important developmental stages. They occur when the brain actively engages in physical, mental, social, or emotional growth. These periods of disrupted sleep often happen when children are busy learning new skills, impacting their sleep patterns.

Signs of Toddler Sleep Regression

If your child previously had a consistent sleep routine but now seems to be experiencing difficulties with sleep, they may be going through a period of sleep regression.

Signs of Toddler Sleep Regression

Your toddler might start waking up more frequently during the night, needing your comfort and attention. They may cry or call out for you, disrupting their sleep and yours. To manage this, try to soothe them back to sleep with gentle reassurance and a consistent bedtime routine.

Your toddler may resist taking their daytime naps or have trouble staying asleep for the usual duration. This can lead to crankiness and fatigue during the day. To address this, establish a relaxing nap time routine and create a comfortable sleep environment to encourage better nap habits.

Your toddler may be more irritable, moody, or prone to tantrums than usual. This could be due to a lack of quality sleep during sleep regression. To help them cope, offer extra comfort, engage in calming activities, and maintain a consistent daily routine to provide stability.

If your toddler wakes up earlier than usual, it could indicate sleep regression. They might be excited about learning a new skill or feeling more independent, prompting them to wake up early and start their day. Alternatively, it could indicate a change in their sleep needs – they may not get enough sleep and feel overtired, or their bedtime might need adjusting if they go to bed too early.

Your toddler might start resisting bedtime, finding excuses to delay going to bed or protesting when it’s time to sleep. This can lead to bedtime battles and frustration for both of you. To overcome this, establish a calming bedtime routine, set clear expectations, and offer reassurance and comfort to help your toddler feel safe and secure at bedtime.

Causes of Toddler Sleep Regression

When a previously good sleeper suddenly starts waking up at night or resisting sleep, parents often seek answers. Pinpointing the exact cause of sleep regression can be challenging, as it may be influenced by various factors. 

Separation anxiety

Just like when they were babies, toddlers also go through phases of separation anxiety, which can trigger sleep regression. Your little one may cling to you and cry for comfort, especially at bedtime. This fear of being apart can disrupt their sleep and lead to regression in their sleep habits. Offering extra reassurance and comfort during this time can help ease their anxiety and improve their sleep.

Physical development

At around two years old, children experience significant leaps in their physical, language, and social development, which can result in more restless nights and difficulties at bedtime. Their increased physical activity and newfound language skills may make settling down harder, leading to more frequent night wakings.  

Potty training

Transitioning from diapers to potty training can lead to toddler sleep regression. As your child learns to use the potty, they may wake up at night needing to go to the bathroom, disrupting their sleep. The excitement or anxiety surrounding this new skill can also make it harder for them to settle down at bedtime.

Establishing a consistent bedtime routine and encouraging them to use the bathroom before bed can help ease this transition and promote better sleep.

A big bed

Switching from a crib to a big bed is a big deal for toddlers. They may start getting up more easily, leading to frequent visits during the night. This change can disrupt their sleep and yours. To help, maintain a consistent bedtime routine and reassure your toddler that they’re safe in their new bed.

Life changes

If your toddler is experiencing a sleep regression, it could be linked to significant changes in their life, such as the arrival of a new sibling, moving to a new house, having a different babysitter, or starting preschool or daycare. These major life events can disrupt their sense of routine and security, leading to behaviour changes and sleep disturbances. 

To help your toddler adjust, try to maintain a consistent routine as much as possible, provide reassurance and support, and offer extra comfort during this transitional period.

Teething

If your toddler is around two years old, they might be getting their molars, which can be uncomfortable or painful. This teething discomfort can make it difficult for them to sleep peacefully through the night. They may wake up crying or fussing due to the discomfort in their gums, disrupting their sleep and yours. 

To help, you can offer teething toys, cold teething rings, or gentle massages to soothe their sore gums before bedtime.

Fears

When your toddler suddenly has trouble sleeping, it could be because they’re starting to see the world more complexly and developing new fears. For example, they might become scared of the dark or imagine frightening things that make it hard to settle down at night.

To help, try addressing their fears using a nightlight to create a sense of security. Encourage open communication to understand their fears and reassure them they’re safe.

Tips for Managing Toddler Sleep Regression

If your child is having difficulty falling asleep or staying asleep, sleep training may be a helpful solution. This involves various methods such as cry it out, no tears, and fading techniques. Additionally, there are alternative strategies you can try to improve your child’s sleep patterns.

Tips for Managing Toddler Sleep Regression

Establishing and maintaining a regular bedtime routine helps your toddler feel safe and secure. This consistent schedule signals to your child that it’s time to relax and get ready for sleep.

According to research, a bedtime routine encourages healthy sleep and promotes emotional and positive development and well-being in early childhood.

Introduce a transitional object, such as a special blanket or stuffed animal your toddler can use as a source of comfort when you’re not physically present. 

Studies indicate that sleeping with a comfort object can help reduce sleep problems and nighttime fears.

Ensure your toddler’s sleep environment is conducive to restful sleep. Keep the room dark, quiet, and comfortable. Consider using white noise machines or soft music to drown out any disruptive sounds that may awaken your toddler during the night.

To address separation anxiety in toddlers, gradually introduce the idea of being apart during sleep by spending a few extra minutes with them before bedtime, reducing the time spent together. Offer verbal reassurance and physical comfort, letting them know you’re nearby and feeling scared is okay.

This approach helps your toddler feel more secure and confident in sleeping independently while maintaining a connection to you.

Ensure your toddler naps are neither too lengthy nor too late. Napping too close to bedtime can disrupt sleep, particularly for toddlers aged 2-3. By scheduling naps earlier in the day and keeping them appropriately timed, you can promote more consistent and restful nighttime sleep for your child.

Encouraging independence and cooperation during bedtime routines for your toddler allows them to express themselves and have some influence over their daily activities, reducing potential power struggles. 

Options like picking out pyjamas or selecting a bedtime story empower your child and promote a sense of control, leading to a smoother and more relaxed bedtime experience conducive to better sleep.

Consistency is key when managing toddler sleep regression. Strive to maintain consistency in your toddler’s sleep routine as much as possible. Stick to established bedtime and naptime schedules and reinforce healthy sleep habits to help your toddler navigate regression periods more easily and resiliently.

Common Ages for Toddler Sleep Regression

While it can be frustrating for parents, it’s important to understand that this regression is normal and temporary.  Sleep regression isn’t experienced by all children; some babies sleep well from the start without any issues. However, many parents notice changes in their child’s sleep patterns around 12 months, 15 months, 18 months, 2 years and 3 years of age.

12-Month Sleep Regression

You may notice your baby experiencing sleep regression at around 12 months old. Despite the general trend toward longer sleep periods at night as babies grow older, sleep development varies greatly among babies. While some may start sleeping through the night around six months, many don’t follow this timeline.

As your child reaches milestones like improved communication and physical skills, they may experience temporary sleep disruptions. These changes in daytime activity and nighttime sleep can lead to a sleep regression. However, with patience and consistency, their sleep patterns will likely normalise over time.

15-Month Sleep Regression

At around 15 months, your toddler is likely going through two significant changes: learning to walk independently and transitioning from two naps to one. With all the excitement of exploring their newfound mobility, they might have trouble settling down for sleep. 

They’re constantly on the move, practising walking around, making it harder for them to wind down at bedtime. 

The shift from two naps to one can disrupt their sleep routine, leaving them more overtired by bedtime. This overtiredness can lead to difficulty falling asleep and more frequent night waking.

18-Month Sleep Regression

Around the middle of their second year, toddlers undergo numerous changes, some contributing to the 18-month sleep regression. Separation anxiety may cause some toddlers to resist bedtime, as they prefer to be close to their caregivers. 

Additionally, toddlers at this age start craving more independence and may resist sleep to practise new skills and explore their surroundings. Despite transitioning from two naps to one, you may suddenly deal with night wakings and nap struggles again at 18 months. 

This could be due to their expanding language skills and increased independence, which may manifest as tantrums during the day and bedtime.

2-Year Sleep Regression

According to a 2005 study, it was discovered that 19 percent of 2-year-olds experienced sleep problems. However, these issues tended to decrease as time passed.

At this age, your toddler may be experiencing significant language development and learning to express themselves with new words and phrases like “No.” They’re also exploring cause and effect, understanding the consequences of their actions. 

It’s important to remain patient and consistent, offering reassurance and maintaining a calming bedtime routine to help your toddler navigate this regression and establish healthy sleep habits.

3 Year Sleep Regression

The 3-year-old sleep regression is a phase that some children may experience as they transition out of the toddler phase. During this time, their world expands, and new fears and phobias may emerge, especially at night. Common experiences include bad dreams, requests to check the closet, and a desire for someone to stay with them at bedtime. 

Additionally, many families begin potty training around age three, which adds another layer of disruption to their sleep routine. Adjusting to the logistics of nighttime potty training and the developmental leap of becoming aware of their bathroom needs can further disrupt their sleep. 

Despite these challenges, providing reassurance, maintaining a consistent bedtime routine, and offering support during this transition can help children navigate the 3-year-old sleep regression and establish healthy sleep habits.

When to Call Your Child's Paediatrician

According to the Sleep foundation, toddlers should get 11–14 hours of sleep daily, including naps. As a parent, it is important to monitor your child’s sleep patterns and notice any signs of insufficient sleep or ongoing sleep problems.

If your child is not getting enough sleep or experiencing consistent sleep disturbances, consult your paediatrician for advice.

Also, if you notice your child frequently snores, has difficulty breathing, or experiences frequent nightmares. It’s important to seek medical attention, as these could be signs of an underlying sleep disorder or health issue that needs to be addressed.
