If your four-month-old baby suddenly wakes up often at night and experiences difficulties falling back to sleep, they might be experiencing sleep regression.
Your baby’s sleep patterns change suddenly at this age. Anecdotal evidence suggests that sleep regression is real and can be difficult for parents and caretakers to handle, but it is a normal developmental phase in babies.
If your baby is about to turn four or you have noticed any changes in their sleeping patterns, read this post to understand what the four-month sleep regression is and how you can manage it.
Why Do Some Babies Go Through Sleep Regression?
Sleep regression can occur at any age, but it is most common at 4, 6, 8, 12, and 18 months. Not all babies experience sleep regression in their fourth month. Research states that there is a significant variation in the individual sleep patterns in newborns (1). Some babies may experience sleep regression due to the following reasons.
- Changing sleep patterns
The sleep patterns in newborns vary according to their age. Newborns tend to sleep for 14–16 hours a day in short intervals. By the age of four to 11 months, babies generally sleep for 12–15 hours a day (2). This change in sleep patterns during the fourth month might result in sleep regression in some babies, as the total time spent sleeping per day is reduced.
- Rapid brain growth and physical growth
Sleep plays a vital role in a newborn’s brain development. During sleep, their brain releases growth hormones, helping in growth and tissue repair. In some babies, sleep regression may be caused by the rapid growth of the brain, a physical growth spurt, or a developmental milestone, such as rolling over, grasping objects, or kicking their legs. The physical growth spurt could lead to frequent awakenings for feeding at night (3) (4).
- Awareness of their surroundings
During the fourth month, your baby becomes more aware of their surroundings and may make sounds such as “coos” and “ah-goos” (4) (5). They also start adjusting to daylight, artificial light, and feeding. Such developments may also result in sleep regression. As they become more aware of the surroundings, they might wake up in between to check if the environment around them is safe. When something doesn’t feel right, they may not drift back to sleep and start crying.
What Are The Signs Of Four-Month Sleep Regression?
Some babies may not show any signs of sleep regression, while others may have difficulty falling asleep at four months or later.
Here are a few signs of sleep regression to help you identify it (6).
- Frequent night waking
- Difficulty in falling asleep
- Fussiness and frequent crying
- Reduced total sleep in a day
A four-month sleep regression could occur suddenly and out of the blue, causing worry to parents. It could also be hard on the parents as it leaves them sleep-deprived. But remember that sleep regressions are normal and could be signs of a healthy baby.
When Does The Four-Month Sleep Regression End?
Although it may feel perpetual, sleep regression does end in a few weeks. However, it depends on how well you manage it and help your baby get back to sleeping peacefully (6).
Read the next section to learn how to manage the four-month sleep regression in your baby.
How To Manage Four-Month Sleep Regression In Babies?
Sleep regression can be hard to handle because it is a sudden development in an otherwise peaceful sleeping baby. It is important to help your baby fall back to sleep and develop a set sleep pattern.
There is no sure-fire way to reduce the four-month sleep regression in babies. However, parents may try the following steps to help develop healthy sleeping patterns in babies.
1. Look for sleep cues.
During the period of four-month sleep regression, it is imperative that your baby catches up on some sleep. Try to identify sleep cues such as yawning, rubbing of eyes, fussiness, quietness, not wanting to play, crying, and clenched fists and settle your baby to sleep (7).
2. Give them time to explore new skills.
At four months, your baby starts to learn new skills, such as reaching out to hold things and rolling over. It is best to give them time to explore and practice these new skills during the day so that they do not try to practice them when you lay them down to sleep at night.
3. Stick to a routine.
This step could be difficult when your baby is going through the four-month sleep regression. Nevertheless, try to stick to their regular bedtime routine. This might help them get back to a normal sleep cycle once the sleep regression ends.
4. Attend to their needs quickly.
Your baby might wake up during the night due to hunger or a wet diaper irrespective of sleep regression. If your baby is crying because of these, make sure you attend to their needs as quickly as possible.
Make nighttime feedings and diaper changes quick, and avoid talking or playing with your baby when they wake up at night. Do not use a bright light or a mobile screen as it can stimulate the baby.
5. Create an optimal atmosphere.
Try to maintain a quiet and dark environment in the nursery. Make sure your baby feels safe in their crib such that even if they wake up in the middle of the night, they can learn to self-soothe back to sleep.
You could also give them a warm bath, massage them, play soothing music, minimize stimulation, and dim the lights at least an hour before sleep to help them fall asleep.
6. Help them self-soothe.
Some babies can soothe themselves back to sleep after waking up at night, whereas others need the caregiver’s help to soothe them. During the four-month sleep regression period, your baby might wake up multiple times during the night. If you rush to take them in your arms, your baby may get accustomed to it. Instead, help them self-soothe.
Do not lift your baby as soon as they cry. Sit by their side, try to hush them by gently patting them, and reassure them that everything is alright. If this does not work, you may pick them up and soothe them to sleep.
7. Feed them adequately.
Ensure your baby is adequately fed before you put them to bed, so they do not wake up at night due to hunger. At four months of age, your baby may not need frequent nighttime feeds, so stick to a strict feeding schedule. Do not use feeding to get them to sleep during the night awakenings, as it might become a habit.
Also, as your baby starts to pay attention to the world around them, it is easy to get distracted and stop feeding midway. Try eliminating distractions while feeding, and make sure they have a full tummy every time.
8. Be gentle with them.
It can be quite challenging to deal with the four-month sleep regression, but remember, it is a part of your child’s developmental process. Do not show anger or frustration towards your baby; instead, shower them with hugs, cuddles, and kisses to comfort them.
9. Seek help from family and friends.
Dealing with sleep regression takes a lot of patience and perseverance, and it is fine to feel overwhelmed at times. Whenever you think you cannot take it anymore, ask your family members or friends to take over while you get some alone time to reboot.
10. Identify the changes in sleep patterns.
During sleep regression, parents often worry if their baby is getting enough sleep. Now that your baby is four months old, they will sleep for 14–15 hours and take three to four naps a day, unlike the 16–17 hours of sleep when they were newborns (2). So, keep track of their sleep timings to avoid unnecessary worrying.
When To Call A Doctor?
Although four-month sleep regression is common, sometimes, there could be underlying medical conditions, such as colic and gastroesophageal reflux, which could lead to sleep disturbances in babies.
Contact your pediatrician if:
- Your baby cries continuously, and no amount of soothing works.
- You notice abnormal breathing, such as gasping for air during sleep.
- Your baby is too lethargic and does not wake up for feeds.
- Your baby does not show normal vital signs.
Four-month sleep regression can be stressful for babies and parents, but remember, your baby will soon outgrow this phase. Take care of yourself during this stressful period. It is natural to feel frustrated; however, do not take it on your baby. Instead, take time off often by giving the baby to your family members or placing them in a safe spot. Compose yourself, and come back and try to soothe your baby.
It may not happen overnight, but sooner or later, your baby will respond to your soothing efforts and fall back to sleep.
