As your toddler reaches the 18-month milestone, you may experience a common sleep problem known as 18 Month Sleep Regression. This can be a challenging time for parents and children alike, but understanding the symptoms and causes of this regression can help you navigate this phase with greater ease.

What is 18 Month Sleep Regression

The 18 Month Sleep Regression is a temporary phase of disrupted sleep that can affect toddlers around 18 months of age. This regression is typically characterized by changes in sleep patterns, difficulty in falling asleep, waking up frequently during the night, and daytime sleepiness and irritability.

While the 18 Month Sleep Regression can be challenging, it is a normal and natural part of your toddler's development. Understanding the causes and potential solutions to this regression can help you support your child through this phase and help them get the healthy sleep they need.

Symptoms of 18 Month Sleep Regression

The symptoms of 18 Month Sleep Regression are almost the same as of other sleep regressions however it may vary between children. Common signs include:

  • Changes in sleep pattern: Your toddler may have trouble falling asleep or staying asleep during the night.
  • Difficulty in falling asleep: Your toddler may take longer to fall asleep and require more soothing than usual.
  • Waking up frequently during the night: Your toddler may wake up several times during the night and require comforting to go back to sleep.
  • Daytime sleepiness and irritability: Your toddler may be more tired during the day, and this can result in increased irritability and moodiness.

Common Causes of 18 Month Sleep Regression

The 18 Month Sleep Regression can be caused by a variety of factors, including:

  • Cognitive development: At around 18 months, your child's cognitive abilities are rapidly developing, and this can lead to increased awareness and curiosity about their surroundings.
  • Separation anxiety: Your toddler may experience separation anxiety and fear of being away from you during the night.
  • Teething: Teething can be painful and uncomfortable, leading to disrupted sleep.
  • Changes in routine: Any changes to your toddler's routine, such as a new sibling or starting daycare, can be stressful and disrupt their sleep patterns.

Effective Solutions for 18 Month Sleep Regression

While there is no one-size-fits-all solution to 18 Month Sleep Regression, there are several techniques that have been effective for many parents and children:

Gradual retreat method

The gradual retreat method involves slowly reducing the amount of time you spend with your child when they wake up during the night. This can involve gradually moving further away from your child's crib or bed each night until they learn to fall asleep on their own.

Bedtime fading technique

The bedtime fading technique involves gradually pushing your child's bedtime later in small increments until they are able to fall asleep more easily. This technique can be effective for children who have trouble falling asleep at bedtime.

Early bedtime

While it may seem counterintuitive, an early bedtime can actually help improve your child's sleep. When your child is overtired, they can become more irritable and have more difficulty falling asleep. An earlier bedtime can help ensure that your child is well-rested and less prone to sleep disruptions.

Dream feeding

Dream feeding involves feeding your child during the night while they are still asleep. This can help reduce night waking and promote more restful sleep.


Co-sleeping can be an effective solution for some families. This involves having your child sleep in the same bed as you or in a bedside crib. Co-sleeping can provide comfort and reassurance to your child, and can also make night feedings easier.

Preventing Future Sleep Regression

While it may not be possible to completely prevent future sleep regression, there are several steps you can take to promote healthy sleep habits for your child:

  • Establish a consistent sleep schedule with a regular bedtime, wake-up time, and nap times.
  • Avoid over-stimulation before bedtime by turning off screens, dimming lights, and engaging in quiet activities.
  • Encourage healthy sleep habits such as ensuring a comfortable and safe sleep environment, using a consistent bedtime routine, and teaching self-soothing techniques.
  • Respond promptly and offer comfort and reassurance when your child wakes up during the night.
  • Be flexible and adapt to your child's changing needs.


18 Month Sleep Regression can be a challenging time, but there are effective solutions that can help ease the transition. By establishing a consistent sleep routine, encouraging self-soothing techniques, and offering comfort and reassurance when your child wakes up during the night, you can help your child develop healthy sleep habits and promote restful sleep. Additionally, by taking steps to prevent future sleep regression and being flexible as your child's needs change, you can set the stage for a lifetime of healthy sleep habits.


How long does 18 Month Sleep Regression typically last?

18 Month Sleep Regression can last for several weeks to a few months, but every child is different.

Can co-sleeping be a long-term solution for 18 Month Sleep Regression?

Co-sleeping can be an effective short-term solution for 18 Month Sleep Regression, but it is important to create a safe sleep environment and transition your child to their own bed when they are ready.

When should I consult with my child's pediatrician about sleep issues?

If you have concerns about your child's sleep habits or if your child is experiencing significant sleep disruptions, it may be helpful to consult with your child's pediatrician to rule out any underlying medical issues and discuss strategies for promoting healthy sleep habits.
