Typically starts around 4 months

The 4-month sleep regression typically starts around the time your baby turns 4 months old. This is because your baby's brain is going through a lot of changes at this time. They are starting to learn new things, such as how to roll over, sit up, and grab objects. They are also becoming more aware of their surroundings and may be more easily startled by things like loud noises or bright lights.

Brain development: Your baby's brain is going through a lot of changes at this time. They are learning new things, such as how to roll over, sit up, and grab objects. This can lead to disrupted sleep as your baby's brain processes all of this new information.
Increased awareness: Your baby is also becoming more aware of their surroundings and may be more easily startled by things like loud noises or bright lights. This can make it difficult for them to fall asleep and stay asleep.
Separation anxiety: Your baby may also be starting to experience separation anxiety around this time. This means that they may become upset when you leave them alone, even for a short period of time. This can make it difficult for you to put your baby down to sleep.
Teething: Some babies start teething around 4 months old. This can cause pain and discomfort, which can make it difficult for your baby to sleep.

If your baby is experiencing the 4-month sleep regression, it is important to remember that it is temporary and that your baby will eventually return to their normal sleep habits. In the meantime, there are a few things you can do to help your baby sleep better, such as establishing a consistent bedtime routine, creating a calming bedtime environment, and avoiding caffeine and sugar before bed.

Can start earlier or later

The 4-month sleep regression typically starts around the time your baby turns 4 months old, but it can start a little earlier or later. Some babies may start experiencing sleep problems as early as 3 months old, while others may not start until they are 5 or 6 months old. There is no one right age for the 4-month sleep regression to start.

There are a few factors that can contribute to the 4-month sleep regression starting earlier or later than usual. These factors include:

Your baby's temperament: Some babies are more sensitive and reactive than others. These babies may be more likely to experience sleep problems, including the 4-month sleep regression.
Your baby's sleep habits: Babies who are used to sleeping in a very quiet and dark room may be more likely to have sleep problems when they are exposed to more noise and light. Babies who are used to being rocked or fed to sleep may also be more likely to have sleep problems when they are put down to sleep awake.
Your baby's health: Babies who are sick or teething may be more likely to have sleep problems. This is because they may be in pain or discomfort, which can make it difficult for them to fall asleep and stay asleep.
Your family's lifestyle: If your family has a lot of changes going on, such as a move or a new baby, this can also disrupt your baby's sleep. Babies need a consistent and predictable routine in order to sleep well.

If your baby is experiencing the 4-month sleep regression earlier or later than usual, it is important to remember that it is temporary and that your baby will eventually return to their normal sleep habits. In the meantime, there are a few things you can do to help your baby sleep better, such as establishing a consistent bedtime routine, creating a calming bedtime environment, and avoiding caffeine and sugar before bed.

If you are concerned about your baby's sleep, talk to your doctor. They can help you rule out any underlying medical conditions that may be causing your baby's sleep problems and recommend strategies to help your baby sleep better.

Usually lasts a few weeks

The 4-month sleep regression typically lasts for a few weeks. This means that your baby may have difficulty sleeping for a period of time, but they will eventually return to their normal sleep habits. The length of the 4-month sleep regression can vary from baby to baby. Some babies may only experience sleep problems for a few days, while others may have sleep problems for up to a few months.

Mild sleep regression: Some babies may only experience a mild sleep regression, which may only last for a few days or a week. During this time, your baby may have difficulty falling asleep, waking up more often at night, or waking up earlier in the morning.
Moderate sleep regression: Other babies may experience a moderate sleep regression, which may last for a few weeks. During this time, your baby may have more difficulty falling asleep, waking up more often at night, and waking up earlier in the morning. They may also be more fussy and irritable during the day.
Severe sleep regression: A small number of babies may experience a severe sleep regression, which may last for up to a few months. During this time, your baby may have extreme difficulty falling asleep, waking up multiple times a night, and waking up very early in the morning. They may also be very fussy and irritable during the day.
No sleep regression: Some babies may not experience a sleep regression at all. This is more likely to happen if your baby has good sleep habits and is used to sleeping in a consistent and predictable environment.

Can last up to a few months

In some cases, the 4-month sleep regression can last up to a few months. This is more likely to happen if your baby is experiencing a severe sleep regression or if there are other factors that are disrupting your baby's sleep, such as illness, teething, or a change in routine.

If your baby's sleep regression is lasting for more than a few weeks, it is important to talk to your doctor. They can help you rule out any underlying medical conditions that may be causing your baby's sleep problems and recommend strategies to help your baby sleep better.

Here are some things you can do to help your baby sleep better during a prolonged sleep regression:

Be patient and consistent: It is important to be patient and consistent with your baby's sleep routine, even if it is taking a long time for them to return to their normal sleep habits. Keep putting your baby down to sleep at the same time each night and following the same bedtime routine each night. Eventually, your baby will learn to fall asleep and stay asleep on their own.
Create a calming bedtime environment: Make sure your baby's bedroom is dark, quiet, and cool. Avoid using electronic devices in your baby's bedroom before bed, as the blue light emitted from these devices can interfere with sleep.
Avoid caffeine and sugar before bed: Avoid giving your baby caffeine and sugar before bed, as these substances can also interfere with sleep.
Talk to your doctor: If you are concerned about your baby's sleep, talk to your doctor. They can help you rule out any underlying medical conditions that may be causing your baby's sleep problems and recommend strategies to help your baby sleep better.

Remember, the 4-month sleep regression is temporary and your baby will eventually return to their normal sleep habits. In the meantime, be patient and consistent with your baby's sleep routine and create a calming bedtime environment. With a little time and effort, your baby will be sleeping soundly again.

It is also important to remember that every baby is different and what works for one baby may not work for another. If you are struggling to help your baby sleep, talk to your doctor or a sleep consultant. They can help you develop a personalized sleep plan that is right for your baby.
