It is common for babies to cry before sleep, and there are many reasons why this may be happening. A 4-month-old baby's brain and body are developing rapidly, and the process of forming and linking different areas of the brain and nervous system may create instability in sleep, known as a sleep regression. During this time, it is common for babies to experience difficulty falling asleep, frequent nighttime awakenings, irritability upon waking, and reduced total sleep time. Sleep training methods such as the cry-it-out (CIO) method can be used to help babies fall asleep independently, but it is important to consider the baby's health and sleep issues before starting any sleep training program.

Sleep regression
The 4-month sleep regression is driven by a permanent biological change in sleep patterns rather than temporary factors like teething or growth spurts. During this time, babies start to cycle through light and deep sleep more like adults. They may fully wake up between sleep cycles and need assistance in falling back asleep. This can lead to more frequent night wakings and shorter naps, as they may call out for their caregivers.
To cope with sleep regression, it is important to establish healthy sleep habits and routines. This includes ensuring that the baby is well-fed, dry, and comfortable before sleep. It is also crucial to be consistent with bedtime routines and create a calm and soothing sleep environment. Additionally, it can be helpful to observe the baby's sleep patterns and allow them to settle back to sleep on their own whenever possible.
While sleep regression can be challenging, it is a normal part of a child's development. Most babies will start sleeping better once they can link sleep cycles and learn to fall asleep independently, which usually happens around 5 to 6 months of age. It is important for parents to focus on their own self-care during this time and seek professional advice if they have any concerns about the baby's development or well-being.

Sleep training
It is common for babies to cry in their sleep or to wake up crying, especially if they are hungry. Babies have shorter sleep cycles than adults and spend more time in light sleep, which means they are more likely to make noises in their sleep.
There are various sleep training methods, and it is important to choose one that suits your baby's temperament and your comfort level. Some methods involve allowing the baby to cry for specific periods, with the parent returning at regular intervals to offer comfort. Other methods focus on gradual changes to minimise crying, such as the Ferber method, which involves timed check-ins, or the wake-and-sleep method, where the baby is woken up to be sleep-trained.
- Ensure the baby is well-fed, dry, and not in any physical discomfort before starting the sleep training technique.
- Establish a bedtime routine and keep bedtime flexible depending on how daytime naps have gone.
- Be consistent in your chosen technique, but don't be afraid to take a break and try a different method if your baby is struggling.
- Keep a video monitor in the room and conduct safety checks every hour.
- If your baby is struggling to fall asleep, crank up some white noise and jiggle the bassinet gently.

Self-soothing
To encourage self-soothing, it is important to establish a routine for independent sleep, which creates a sense of predictability, providing comfort and security for the baby. This includes ensuring the baby is well-fed, dry, and not in any physical discomfort before putting them in their crib while still awake and then leaving the room. It is also recommended to keep a video monitor in the room and conduct safety checks every hour. While some babies fall asleep within 10 minutes, others may cry for longer.
It is common for babies to briefly call out in between sleep cycles, and it is tempting to help them back to sleep. However, it is often helpful to wait a few minutes before responding, as they may settle back to sleep on their own. This can also help shift them into a different stage of sleep and stop them from crying. Observing a baby's sleep pattern can be useful in understanding their sleep needs.

Sleep cycles
A 4-month-old baby's sleep cycle is quite different from that of an adult. At this age, babies typically experience a biological shift in the way they sleep, which is often referred to as the "4-month sleep regression". This regression marks a change in the stages and cycles of sleep, as they begin to have additional cycles of light and deep sleep, similar to an adult's sleep pattern. This maturation in sleep can result in increased night waking and shorter naps.
During this period, it is common for 4-month-olds to wake up more frequently at night due to the change in their sleep cycles. They will start having cycles of light and deep sleep and will briefly awaken after each sleep cycle. While this is normal, as adults also briefly wake between sleep cycles, it can lead to crying overnight and/or taking short naps if they are unable to fall back to sleep on their own.
The sleep cycles of babies are shorter than those of adults, typically lasting about 40 minutes, which is why they tend to wake up more often. Babies spend more time in light sleep or REM sleep, which makes it easier for them to wake up. As they grow older, they will experience less REM sleep and will transition to more non-REM sleep cycles, slowly moving towards an adult sleep cycle.
While it can be challenging to navigate a 4-month-old's sleep cycles, there are some strategies that can help. Establishing a daily routine and a consistent nighttime sleep routine can aid in improving sleep patterns. Additionally, sleep training can be beneficial for some babies, leading to longer stretches of sleep. However, it is important to manage expectations as many babies at this age will continue to need assistance at bedtime and during the night. Gentle methods like gradual withdrawal or pick-up-put-down are often more suitable than intensive methods like total extinction.

Circadian rhythm
A 4-month-old baby crying before sleep is a common occurrence and is usually not a cause for concern. Babies at this age are still developing their circadian rhythm, which is their internal body clock that regulates their sleep-wake cycles.
The Developing Circadian Rhythm
During the first few months of life, babies are still adjusting to the outside world and learning the difference between day and night. Their sleep patterns are often disorganized, with short sleep cycles and frequent waking periods. This is because they have yet to establish a clear sleep-wake rhythm like older children and adults.
Sleep Regression
Around 4 months of age, some babies experience sleep regression, which is a change in their sleep pattern. They may start sleeping longer stretches or even through the night, while others may continue to wake frequently. This variation in sleep patterns is normal and expected.
Sleep Training and Crying
Sleep training methods, such as the cry-it-out (CIO) approach, are designed to help babies learn to fall asleep independently. However, it is important to note that sleep training is generally not recommended before 4 months of age. At this early stage, higher parental involvement methods, such as "`pick-up-put-down`" or gradual withdrawal, are often more suitable.
Reducing Crying and Promoting Sleep
To reduce crying and promote healthy sleep habits, consistency and routine are key. Establishing a daily routine and a nighttime sleep routine can help regulate your baby's circadian rhythm. This includes creating positive sleep associations, such as a calming bedtime routine, and avoiding negative sleep associations, like always holding your baby until they fall asleep.
Additionally, understanding your baby's cues and tending to their basic needs, such as feeding and changing, are crucial. Ensuring your baby is well-fed, dry, and comfortable before sleep can help reduce crying and improve sleep. Remember, crying is your baby's way of communicating their needs, and it is normal for them to cry before or during sleep as they transition through sleep cycles.
