Sleep Regression: Understanding Your Toddler's Mind

what happens psychologically during sleep regression in toddlers

Sleep regression is a common phenomenon in toddlers, characterised by a temporary disruption in their regular napping and nighttime sleep schedules. While it can be challenging for both toddlers and their caregivers, it is important to understand that sleep regression is not a regression in the true sense of the word, but rather a normal part of a child's growth and development. During these periods of intense development, toddlers may experience setbacks in their sleep patterns, such as increased fussiness, shorter naps, and refusal to sleep at bedtime. These setbacks can be influenced by various factors, including physical achievements, separation anxiety, life changes, and approaching developmental milestones. While sleep regression can occur at any time, there are predictable ages where it commonly occurs, including around 12 months, 15 months, 18 months, and the 2-year and 3-year marks. Fortunately, sleep regression is typically temporary, lasting only a few weeks, and with patience, commitment to a solid bedtime routine, and understanding of the underlying causes, toddlers can overcome these sleep challenges.

Sleep regression is a normal part of toddler development

Sleep regression in toddlers can occur at various ages, commonly around 12 months, 15 months, 18 months, 2 years, and 3 years. However, it is important to note that each child's development is unique, and sleep regression can occur at different ages or even multiple times throughout toddlerhood. The timing of sleep regressions is often associated with periods of intense development, growth spurts, and milestone achievements.

During sleep regression, toddlers may exhibit signs such as increased fussiness, climbing out of bed, and early morning wake-ups. These behaviours are not intentional, and it is essential to understand that they are a normal part of a toddler's growth and development. Sleep regression can be influenced by various factors, including physical achievements, such as pulling up, cruising, walking, and climbing, which can cause excitement or confusion, impacting their sleep.

Additionally, separation anxiety, a common phase in toddlerhood, can also contribute to sleep regression. Toddlers may experience clinginess and cry for their favourite people, usually their parents. This can lead to stalling techniques, power struggles, or playing instead of sleeping. It is important for caregivers to provide comfort and support during these times, as toddlers navigate their emotions and sleep patterns.

To manage sleep regression, maintaining a consistent bedtime routine and sleep schedule is crucial. A calming routine that includes activities such as feeding, bathing, reading, and lullabies can help signal to the toddler that it is time to wind down and prepare for sleep. Caregivers should also be patient and understand that sleep regression is a normal phase that will pass as the toddler continues to develop and adjust their sleep patterns.

It can be caused by nightmares, night terrors, fear of the dark, teething, and separation anxiety

Sleep regression in toddlers can be caused by nightmares, night terrors, fear of the dark, teething, and separation anxiety.

Nightmares can be a disruptive cause of sleep regression in toddlers. If nightmares are severely affecting a child's sleep, it is recommended that parents discuss this with a pediatrician, as it could be related to a sleep disorder, anxiety, or another concern. Nightmares are a common cause of sleep regression, and speaking with a healthcare provider can ease worries, as parents can learn that these sleep issues are normal in toddlers and should improve over time.

Night terrors are another cause of sleep regression. Night terrors are similar to nightmares but are far more dramatic and alarming to witness. A child having a night terror may wake up screaming and cannot be comforted. The child eventually calms down and goes back to sleep, usually with no memory of the night terror. Night terrors occur when a child is partially awake, and the brain's "fight-or-flight" response becomes overexcited, causing the child to feel panicked and terrified. Night terrors are most common in children younger than 13 years old and often run in families. They usually disappear before the teen years, and parents can learn strategies from doctors to help manage them.

Fear of the dark can also contribute to sleep regression in toddlers. Toddlers may express fear of monsters in their room or anxiety about being closed in the dark. Parents can help alleviate this fear by standing at the door and telling the child that monsters are going away and that their bed is a safe place. Playing games during the day where the bed is designated as a safe spot can help reinforce this idea.

Teething is a common cause of sleep regression in toddlers. The discomfort from erupting teeth can lead to increased night wakings, shorter naps, resistance to sleep, and sleep disruptions. Teething pain typically resolves in about a week, but sleep challenges may persist if new sleep associations, such as rocking to sleep, were introduced during this period. To help soothe teething pain, parents can try gum massages, teethers, and doctor-approved pain relievers.

Separation anxiety is a normal developmental phase in toddlers that can contribute to sleep regression. It often manifests at night because overnight sleep marks a long period of separation from caregivers. Toddlers may cry, become extra clingy, or resist being placed in their cribs. Separation anxiety can cause a child's body to be on higher alert, disrupting their sleep patterns and leading to more frequent wakings and shorter or skipped naps.

It can also be triggered by physical development, like learning to walk

Sleep regression in toddlers is a temporary phase where a child who was sleeping well suddenly starts waking up more often, taking shorter naps, or fighting bedtime. This is common during times of developmental growth or big transitions, such as learning to walk.

Learning to walk is a significant physical milestone that can impact a toddler's sleep patterns. The desire to practice this new skill can interfere with their sleep, leading to night wakings or nap refusals. The physical exertion of learning to walk can also make toddlers extra fussy or grizzly, affecting their sleep. They may also experience muscle soreness, making it uncomfortable to lie down and rest. Additionally, the mental and physical exertion of learning to walk can cause toddlers to sleep more than usual, similar to how new experiences can impact an adult's sleep.

The impact of learning to walk on sleep can be mitigated by practicing walking and other developmental milestones during the day. This helps toddlers master their new skills while reducing the disruption to their nighttime sleep. Sleep training can also be beneficial in establishing good sleep habits and reducing the impact of future developmental milestones on sleep.

It's important to remember that sleep regression, while challenging, is a normal and temporary phase. Toddlers are constantly growing and developing, and their sleep patterns may fluctuate as they reach new milestones. By sticking to a consistent bedtime routine and being patient, parents can help their toddlers navigate these changes and get back on track with their sleep.

Regression can be caused by changes in routine, like sickness or travel

Sleep regression is a common phase in a toddler's development, where they experience a temporary disruption in their sleep patterns. This can manifest as waking up more frequently during the night, taking shorter naps, or resisting bedtime. While sleep regression is usually associated with developmental milestones, it can also be triggered by changes in routine, such as sickness or travel.

Regression caused by changes in routine can be particularly challenging for both toddlers and their caregivers. A sick toddler, for instance, may need more comfort and attention during the night, disrupting their sleep and that of their caregivers. Similarly, travelling can disrupt a toddler's sleep schedule and routine, leading to sleep regression.

When a toddler falls sick, their sleep patterns may be affected due to various reasons. They may experience discomfort or pain, making it difficult to fall asleep or stay asleep. They may also need to wake up frequently to use the bathroom, take medication, or receive comfort and reassurance from their caregivers. Additionally, sickness can cause fatigue and exhaustion, leading to increased sleep during the day and disrupted sleep at night.

Travel can also trigger sleep regression in toddlers. Changes in environment, such as sleeping in a new or unfamiliar place, can make it harder for toddlers to relax and fall asleep. They may miss the familiarity and comfort of their own beds and routines. Travel can also disrupt their regular sleep schedules, with changes in time zones, nap environments, and daily routines. These factors can contribute to sleep regression, making it challenging for toddlers to maintain consistent and restful sleep patterns while away from home.

To manage sleep regression caused by changes in routine, it is essential to prioritize consistency and comfort. Caregivers should aim to maintain a familiar bedtime routine as much as possible, even when their toddler is sick or travelling. This can include sticking to the same bedtime rituals, such as reading a book, singing lullabies, or providing comforting words. Ensuring that the toddler is getting enough sleep during the day can also help prevent overtiredness, which can exacerbate sleep regression. Additionally, creating a soothing sleep environment, addressing any discomfort or fears, and providing extra comfort and reassurance can help toddlers feel more secure and relaxed during periods of sleep regression.

To help your toddler, stick to a consistent bedtime routine

Sleep regression is a common phenomenon in toddlers, characterised by interruptions in their regular napping and nighttime sleep schedules. It is typically triggered by periods of intense development, growth spurts, and transitions, such as walking, talking, potty training, or starting preschool. While sleep regression is temporary, it can be challenging for both toddlers and their caregivers.

To navigate this tricky phase, it is essential to stick to a consistent bedtime routine. Here are some detailed suggestions to help your toddler establish a calming and predictable bedtime routine:

  • Recognise sleep cues: Pay attention to your toddler's sleep cues, such as rubbing their eyes, fussiness, yawning, or looking away. By noticing these cues, you can put your toddler to bed before they become overtired, which can make falling and staying asleep more difficult.
  • Maintain a consistent bedtime: Establish a regular bedtime and stick to it. This helps set your toddler's internal clock, making it easier for them to fall asleep and maintain a healthy sleep schedule.
  • Follow a calming routine: Develop a calming bedtime routine that includes soothing activities such as a warm bath, reading a book, singing lullabies, or sharing comforting words. This routine should be consistent and followed every night to signal to your toddler that bedtime is approaching.
  • Address sleep needs: Ensure your toddler is getting adequate sleep during the day. Toddlers still need regular naps and sufficient overall sleep. Overtired toddlers may struggle more with falling asleep and maintaining a healthy sleep schedule.
  • Create a comfortable sleep environment: Make sure your toddler's bedroom is conducive to sleep. Check that the temperature is comfortable, and use tools like white noise machines or blackout curtains to minimise distractions from noise or light. If your toddler is afraid of the dark, a nightlight or a dim hallway light can provide a sense of comfort.
  • Provide comfort objects: Offer your toddler a comfort object, such as a soft toy or a blanket, to help them feel secure at bedtime. These objects can become a source of comfort and reassurance during the night, potentially helping them self-soothe back to sleep if they wake up.
  • Be patient and consistent: Sleep regression can be frustrating, but it is important to remain patient and committed to the bedtime routine. Consistency is key. Even if your toddler resists or struggles with sleep, continue following the established routine, as this familiarity will provide comfort and security.
  • Gradual sleep training: Sleep training techniques, such as the "graduated extinction" method, can be introduced gradually. This involves slowly increasing the time you wait before responding to your crying toddler after putting them to bed. This approach allows your toddler to learn self-soothing techniques while still receiving comfort and support from you.

Remember, sleep regression is a normal part of a toddler's development, and it will pass. By sticking to a consistent bedtime routine, you can help your toddler navigate this challenging phase and get back on track with their sleep.
