After entering into your world, I believe that your little love has been your “sleep timer.” You can drift into sleep peacefully only when your baby falls into sleep.

Affected by many factors, babies can experience it at any time, ranging from 4 months to 12 months.
Speaking of its duration, for most babies, sleep regression typically occurs within several weeks to months. Besides, some lucky dogs may miss it successfully.

When does the whole sleep regression end completely

Generally speaking, you can’t predict the time when your baby will recover from the sleep regression. It’s a pity that it will last for weeks and even longer. Fortunately, your babies return to normal at last.

  2. Rapidly falling asleep: Without relying on excessive soothing, babies can fall asleep in a rapid way when bedtime arrives.
  3. Extended sleep cycle: With the infant gradually growing older, the sleep cycles lengthen. Instead of waking up frequently, babies can stay asleep for a long time.

Sleep regression is a part of babies’ physical development. Although it may bring some challenges, it is a significant symbol of babies’ growth.
Firstly, as sleep development advances, the sleep quality of babies will improve. For example, it prolongs nighttime sleep, reduces the times of nighttime awakenings, and establishes a more stable schedule.
Secondly, during this stage, without relying on external assistance, babies learn to fall into sleep independently and enter into the adult-like sleep pattern.

In a word. sleep regression is an important milestone in the development of babies. During this stage, babies’ sleep patterns plus requests change significantly, which has a profound impact on babies.

The reasons of sleep regression are as follows:

  1. The persistence of separation anxiety: Disturbed by it, babies are prone to wake up at night in the absence of their parents.
  2. Developmental milestone: Babies continue to grow up and acquire new motor skills, such as standing, walking, or climbing furniture. This behavior is the main reason for night awakenings.
  3. Teething: Babies’ teeth are still growing. The process probably causes discomfort or even aches, which reduces the sleep quality of babies.
  4. Circadian rhythm adjustment: Babies are likely to set up a more stable daytime and nighttime sleep cycle, but this process may cause some temporary changes in sleep patterns.


It varies based on the individual differences of babies, ranging from weeks to months.

Don’t worry. It would be help if you let your babies move freely in the daytime to stimulate their senses. As evening comes, you’d better create a quite environment.
