Baby Sleep Regression at 18 Months: Understanding and Managing the Changes

Baby Sleep Regression 18 Months


As your baby grows and develops, you may encounter various sleep challenges along the way. One common milestone that can disrupt sleep patterns is the 18-month mark, often referred to as the “baby sleep regression.” This period can be challenging for both babies and parents, as it brings about changes in sleep routines and patterns. In this article, we will explore the reasons behind baby sleep regression at 18 months and provide helpful strategies to manage this phase effectively.

What is Baby Sleep Regression at 18 Months?

Baby sleep regression refers to a period when a previously good sleeper begins to experience disruptions in their sleep patterns. At around 18 months, many babies go through a sleep regression phase characterized by changes in their sleep habits, increased night waking, and difficulties settling down for sleep. This regression can be attributed to various factors, including cognitive and physical development, separation anxiety, and emerging independence.

Common Signs of Sleep Regression at 18 Months

During the 18-month sleep regression, you may notice the following signs in your baby:

  1. Increased night waking: Your baby may wake up more frequently during the night, requiring your attention and assistance to settle back to sleep.
  2. Resistance to bedtime: Your baby may resist going to bed and display signs of protest or frustration when it’s time to sleep.
  3. Shortened naps: The duration of your baby’s naps may become shorter, affecting their overall daytime sleep.
  4. Changes in sleep routine: Your baby’s established sleep routine may no longer work, and they may require different strategies to help them fall asleep and stay asleep.
  5. Irritability and fussiness: Sleep disruptions can lead to increased irritability and fussiness during the day due to tiredness and disrupted sleep.

Strategies to Manage Baby Sleep Regression at 18 Months

While baby sleep regression at 18 months can be challenging, there are strategies you can employ to help manage this phase:

1. Maintain a Consistent Routine

Stick to a consistent sleep routine to provide your baby with a sense of predictability and security. Establish a calming pre-sleep routine that includes activities such as reading a book, singing a lullaby, or gentle cuddling. Consistency and familiarity can help your baby feel more relaxed and prepared for sleep.

2. Create a Comfortable Sleep Environment

Ensure that your baby’s sleep environment is conducive to sleep. Keep the room dimly lit, maintain a comfortable temperature, and use white noise or a sound machine to drown out any external disturbances. Providing a cozy and soothing sleep environment can help your baby settle more easily during this period of regression.

3. Address Separation Anxiety

At 18 months, separation anxiety often intensifies, leading to increased nighttime waking and resistance to being alone in the crib. Respond to your baby’s needs with reassurance and comfort, but gradually encourage self-soothing skills by gradually increasing the time between responses. This can help your baby develop a sense of security and independence.

4. Adjust Nap and Bedtime Schedules

Reevaluate your baby’s nap and bedtime schedules to ensure they are appropriate for their age and developmental stage. It may be necessary to make adjustments to accommodate their changing sleep needs during the regression. Monitor your baby’s tired cues and consider slightly adjusting nap times or bedtime to prevent overtiredness.

5. Offer Comfort and Reassurance

During the sleep regression, your baby may require additional comfort and reassurance. Respond to their needs promptly and provide gentle soothing techniques such as patting their back, singing softly, or offering a lovey or favorite toy. The aim is to help them feel secure and supported during this challenging phase.

6. Seek Support and Understanding

Remember that baby sleep regression at 18 months is a temporary phase that will eventually pass. Seek support from other parents or join online communities to share experiences and gain insights. Having a support system can provide comfort and reassurance during this challenging time.

Baby Sleep Regression at 18 Months FAQs

FAQ 1: How long does the 18-month sleep regression last?

The duration of the 18-month sleep regression can vary from baby to baby. While some babies may experience it for a few weeks, others may go through a more extended phase. On average, it typically lasts between two to six weeks.

FAQ 2: Should I change my baby’s sleep training method during the regression?

If you were using a sleep training method before the regression that was effective, it’s generally advisable to stick with it. However, you may need to offer additional comfort and support during this phase. If you haven’t implemented a sleep training method, consider gradually introducing gentle techniques to help your baby settle and soothe themselves back to sleep.

FAQ 3: Is it normal for my baby’s appetite to change during the regression?

Yes, it’s common for a baby’s appetite to fluctuate during the sleep regression. Some babies may experience a temporary decrease in appetite due to disrupted sleep patterns and increased tiredness. Offer nutritious meals and snacks throughout the day, and consult with your pediatrician if you have concerns about your baby’s eating habits.

FAQ 4: Can teething contribute to the 18-month sleep regression?

Teething can coincide with the 18-month sleep regression and contribute to sleep disruptions. Teething discomfort can cause your baby to wake up more frequently during the night. Provide appropriate teething relief measures, such as teething rings or chilled washcloths, to help alleviate discomfort.

FAQ 5: When should I consult a pediatrician about my baby’s sleep regression?

If you’re concerned about your baby’s sleep regression or if it significantly impacts their overall well-being and development, it’s recommended to consult with your pediatrician. They can evaluate your baby’s specific situation, address any underlying concerns, and provide personalized guidance and support.

FAQ 6: Will my baby’s sleep patterns return to normal after the regression?

Yes, most babies’ sleep patterns do eventually return to normal after the regression phase. As your baby adjusts to developmental changes and gains new skills, their sleep patterns will stabilize. Implementing consistent sleep practices and providing a nurturing sleep environment can help facilitate this transition.


Baby sleep regression at 18 months can be a challenging phase for both babies and parents. Understanding the reasons behind the regression and employing effective strategies can help navigate this period with greater ease. Remember to provide consistency, comfort, and reassurance to your baby while maintaining realistic expectations. As the regression phase eventually passes, your baby will settle into more stable sleep patterns, allowing for restful nights and well-rested days for the entire family.
