How long do babies sleep in the womb?
Babies in the womb, known as fetuses, spend a significant amount of time sleeping while their tiny bodies grow and develop. During the third trimester of pregnancy, which spans from the 28th week until birth, babies sleep for approximately 20 hours a day. This extended period of sleep is essential for their overall development. It allows their brains to mature, facilitates physical growth, and supports the functioning of various organs and systems.
According to renowned obstetrician and gynecologist, Dr. Michel Odent, “The function of sleep in late pregnancy is not really known, although it is likely to play a vital role in the growth process of the fetus.” This highlights the significance of sleep for unborn babies and emphasizes its role in their well-being.
Here are some interesting facts about babies’ sleep in the womb:
-
Sleep-wake cycles: Fetal sleep patterns vary, and they experience periods of both active sleep (or REM sleep) and quiet sleep (or non-REM sleep). These cycles resemble those observed in newborns and adults.
-
Movement during sleep: While sleeping, babies can be observed moving, stretching, and even practicing various physical movements. These movements are crucial for the development of their muscles and coordination.
-
Sensory experiences: Although the womb lacks external stimuli as experienced outside, fetuses can still engage in sensory experiences. They can hear their mother’s voice, feel gentle touches or vibrations, and even respond to light.
-
Circadian rhythm: Fetuses do not have a fully developed circadian rhythm, which is the internal biological clock that regulates sleep-wake cycles. However, they can still exhibit patterns of increased movement during the evening and night, corresponding to their mother’s resting periods.
To provide a comprehensive overview, here is a table summarizing the sleep patterns during the third trimester of pregnancy:
| Sleep Stage | Hours per Day |
|---|---|
| Active Sleep | 8-10 hours |
| Quiet Sleep | 8-10 hours |
| Transitional | 1-2 hours |
| —————- | ————— |
| Total Sleep | 20 hours |
While the exact purpose and nature of fetal sleep are still being studied, it is evident that it plays a significant role in the development and growth of the baby in the womb. The remarkable amount of time spent sleeping demonstrates the importance of a conducive sleep environment and overall maternal well-being during pregnancy.

This section of the video discusses the development of the baby during weeks 26-29 of pregnancy. By week 27, the baby can distinguish between the mother’s voice and the partner’s voice, despite being underwater and having plugged ears. At 28 weeks, the baby starts to open his eyes and blink, while his skin remains wrinkly but will eventually fill out. By week 30, the baby weighs approximately 3 pounds and has cycles of sleeping and waking. The cramped space in the uterus may cause the baby to kick to let the mother know when he is awake.

Do Babies Sleep in the Womb? Just like newborns, fetuses spend most of their time sleeping. Indeed, throughout much of the pregnancy, your baby sleeps 90 to 95% of the day. Some of these hours are spent in deep sleep, some in REM sleep, and some in an indeterminate state—a result of their immature brain.
On average, unborn babies sleep for about 14 to 16 hours in a 24-hour period, often broken up into shorter periods rather than one long stretch.

In this regard, How many hours does fetus sleep in the womb? Your baby is the size of a pomegranate and weighs close to 11 ounces. Taste buds have developed, and your little one can swallow.

Hereof, What weeks do babies sleep the most in the womb? As a response to this: Yes. In fact, as far as we can tell, babies spend the majority of their time in the womb sleeping. Between 38 and 40 weeks gestation they’re spending almost 95 percent of their time sleeping. Less is known about sleep during early fetal development.
Do babies wake up in the womb?
Response to this: "There’s been a lot of disagreement about whether embryos ever wake up before they’re born, and the scientific consensus is that they don’t," Balaban says.
When can a baby survive outside of the womb? As an answer to this: Here’s what we can tell you. Doctors now consider 22 weeks the earliest gestational age when a baby is "viable," or able to survive outside the womb. But this is still extremely premature, and a baby born at this age will need a great deal of medical attention.
Also Know, When do babies Laugh In their sleep? The reply will be: Babies usually start laughing “between 2-4 months” says Nina Pegram, pediatric nurse practitioner and lactation consultant with SimpliFed.
