Sleep Regression: Signs Your Baby Has Moved Past It

Sleep regression is a common phenomenon in babies, and it can be a challenging time for both the child and the caregiver. The 4-month sleep regression is often the first and most difficult one for parents to navigate. It is characterised by a sudden worsening of sleep patterns, with babies waking up more frequently at night and finding it harder to fall back asleep. This usually occurs when babies are going through a growth spurt or a developmental leap, such as learning to roll over or becoming more aware of their surroundings. While it can last anywhere from two to six weeks, there are strategies to help your baby and you get through it. These include maintaining a consistent bedtime routine, ensuring your baby is well-fed during the day, creating a calm and dark atmosphere for sleep, and giving your baby the opportunity to fall asleep independently. While it may be exhausting, remember that this phase is temporary and an important part of your baby's development.

It lasts 2-6 weeks

The 4-month sleep regression typically lasts for 2-6 weeks. However, it's important to remember that every baby is different, and the duration of this sleep regression can vary. Some babies may experience sleep issues for shorter or longer periods.

During this time, it's crucial to focus on helping your baby develop healthy sleep habits and routines. Here are some tips to navigate the 4-month sleep regression:

• Consistency is key: Stick to a consistent bedtime routine. This will help your baby unwind before bed and reinforce the association between nighttime and sleep.
• Encourage independent sleep: Help your baby learn to fall asleep independently. Put them down when they are drowsy but still awake, so they can practice falling asleep on their own.
• Maintain a dark sleep environment: Invest in blackout curtains or use thick blinds to block out light. A dark room can encourage longer sleep and help your baby link their sleep cycles, resulting in more consolidated sleep.
• Pay attention to wake windows: Aim for wake windows of 90-120 minutes for 4-month-olds. This will help prevent overtiredness, which can make it harder for your baby to fall asleep and stay asleep.
• Offer extra love and affection: Remember that your baby is going through a lot of changes, and their sleep may be disrupted. Offer lots of hugs, cuddles, and kisses to provide comfort and security.
• Reach out for help: Don't hesitate to ask for help from family and friends. Taking care of yourself is important, too, so take breaks when you can and get some extra sleep if possible.
• Be patient: This sleep regression is a normal part of your baby's development, and it will pass. Focus on providing a supportive and consistent sleep environment, and know that things will get better.

Remember, the 4-month sleep regression is a temporary phase, and with patience, consistency, and some trial and error, you'll get through it!

It's caused by a baby's brain development

At around four months, a baby's brain and body are developing rapidly. The process of forming and linking different areas of the brain and nervous system may create instability in sleep, which is referred to as a sleep regression.

A newborn needs between 16 and 18 hours of sleep per day, which typically comes in one- to three-hour segments throughout the day. This starts to change around three to four months of age when a baby's sleep starts to consolidate, meaning they begin to sleep for longer periods at a time. While multiple naps are still the norm, they may have longer nighttime sleep sessions and sleep fewer total hours.

The process of sleep consolidation varies significantly from child to child. Some babies experience a smooth transition through sleep patterns, while others may have disruptions to their sleep duration and quality. A four-month sleep regression can occur because babies are in the midst of a major transition away from a newborn sleep pattern. This transition is not always smooth and may have setbacks like sleep regressions.

There is typically no single cause for a four-month sleep regression, but some contributing factors may include a greater awareness of their surroundings, which can result in overstimulation; an uneven transition into consolidated sleep; and disturbances in the infant's sleep environment.

The good news is that if your baby is experiencing sleep regression, it may mean they're going through a growth spurt or that their brain is developing. Your baby's brain is constantly evolving as it adapts to its new environment and begins to learn new skills. At this time, your baby might be working hard to master how to roll over or sit up. This time of learning can be stressful and frustrating for your baby, and their sleep patterns might reflect that.

Sleep regression is the time when your baby's sleep patterns shift, they wake up often during the night, and they have a hard time going back to sleep. The first sleep regression often happens when your baby is about four months old, and others might occur in the future. Since it's the first, the four-month sleep regression is often the hardest for parents.

Sleep regressions are completely normal and often occur at predictable times during your little one's first year. They typically last anywhere from two to four weeks, and while they are common, not every baby will have a sleep regression at this time.

It's not permanent

Sleep regressions are a normal part of a baby's development and usually happen when they are going through a big developmental milestone. Your baby is learning new skills and their sleep patterns might reflect that.

The first sleep regression often happens when your baby is about four months old, and others might occur in the future. Since it's the first, the four-month sleep regression is often the hardest for parents. Sleep regressions typically last anywhere from two to six weeks, and while they are common, not every baby will have a sleep regression at this time.

The four-month sleep regression is the first of the most common sleep regressions and the only sleep regression that's actually related to a biological change in sleep. While all sleep regressions are associated with developmental progression, there is a shift in sleep around four months when babies move from the newborn phases of sleep into more adult-like sleep stages.

Sleep regressions are not permanent and can be overcome by encouraging healthy sleep routines and habits for your baby.

It's a common occurrence

Sleep regression is a typical phase in a child's development where they experience a backward shift in their sleep patterns. It usually happens around the four-month mark, but it can occur earlier or later. During this time, babies who were previously sleeping well throughout the night may start waking up frequently and find it challenging to fall back asleep. This phase can be frustrating for parents, as it disrupts their sleep as well.

The good news is that sleep regression is a normal and temporary part of a baby's growth and development. It often coincides with significant milestones, such as growth spurts and the baby's brain development. At this stage, their sleep patterns start to mature, and they experience more cycles of light sleep and deep sleep, similar to adult sleep patterns.

While not all babies go through the four-month sleep regression, it is a common experience for many. It's important to note that the timing and nature of sleep regressions can vary for each baby. Some babies may experience sleep disruptions earlier or later than four months, and not all will have sleep issues.

This phase usually lasts for about two to six weeks, but it can be shorter or longer for some babies. To help your baby through this time, it's recommended to establish consistent bedtime routines, encourage them to fall asleep independently, and create a calm and dark sleep environment.

• Sudden worsening of night sleep
• Increased crying or fussiness during sleep times and difficulty settling
• Disrupted naps and less total daytime sleep
• Distracted daytime eating
• Increased night wakings with crying or fussiness
• Reduction in total sleep duration

It can be managed with a routine

It can be frustrating and tiring when your baby experiences sleep regression. However, it's important to remember that it's a normal part of their development. Here are some tips to help you manage and get through the four-month sleep regression:

Establish a bedtime routine

Stick to a consistent bedtime routine. This will encourage your baby to unwind before bed and reinforce that nighttime is for sleeping. Include activities such as feeding, bathing, changing clothes, reading a story, or singing a lullaby. Being consistent with your approach is more important than the specific activities you choose.

Encourage your baby to fall asleep independently

Help your baby learn to fall asleep independently by putting them down when they're drowsy but not fully asleep. This will enable them to fall back asleep more easily when they wake up in the middle of the night.

Maintain adequate feedings during the day

Ensure your baby gets enough to eat throughout the day so they're not hungry at night or midway through a nap. Offer feedings every 2.5 to 3.5 hours, following their hunger cues. Remember that the four-month sleep regression can lead to "reverse cycling," where your baby takes in most of their calories at night instead of during the day.

Expand wake windows

At four months, aim for wake windows between 90 and 120 minutes. Sufficient active awake time during the day will help your baby sleep better at night and take longer naps. The first wake window of the day is usually around 90 minutes, while the others are closer to 100-110 minutes, and the last one before bedtime is about 120 minutes.

Create a calm atmosphere

Avoid overstimulating your baby before bedtime with screen time or energetic play. Instead, opt for calming activities like reading a book or softly singing a lullaby. Set the mood with minimal lighting and visual distractions, and consider using a white noise machine to promote relaxation.

Remember, the four-month sleep regression is typically a temporary phase, and you can help your baby through it by establishing healthy sleep habits and routines.
