Babies and Sleeping in the Womb

FAQ #1

Does baby sleep in womb, really?

  • Yes! Babies are asleep in the womb more than you might realize. Not much is known about babies and their sleep habits during the earliest stages of pregnancy, but by month seven, it is proven that babies have rapid eye movement, which signifies they are in deep sleep.
  • It’s easy to tell when your baby is awake because they’re probably kicking you now and then. However, it might not be as easy to tell if your child is sleeping. Some expectant moms are very in-tune with their baby’s sleep cycle, while others may not be able to tell.

FAQ #2

How much does a baby sleep in the womb?

  • Although we don’t know much for sure about the sleep habits of babies in the womb, it is estimated that a baby who has reached 38 weeks sleeps up to 95% of the time while they are in the womb.
  • How many hours baby sleep in womb depends on the individual baby as well as the lifestyle of the mother.
  • However, most babies will sleep almost all the time they are in the womb and will only wake up now and then to move around, kick, and flutter.

FAQ #3

Does the baby sleep in the womb when the mother sleeps?

  • Sometimes! The baby’s sleep cycle isn’t as dependent on the mother’s as the other way around. Moms may be awoken by the baby moving around during the night, which can cause the expectant mom to get up and move around too until the baby settles down again.
  • Of course, since babies sleep in the womb up to 95% of the time, they are asleep a lot of the time when the mother is, too.

FAQ #4

How do you know baby is awake in the womb?

It’s usually easy for expectant moms to tell when older babies are awake because they can feel kicking! Babies move, kick, flutter, and generally make their presence known when they’re awake, especially when they get a little bit bigger and closer to the delivery date.

FAQ #5

Is sleep in the womb a crucial factor for a baby’s development?

Probably—but research is still working on better understanding the relationship between sleep in the womb and baby development. Babies who are born prematurely sleep and dream to help their brains and senses develop, so there is a good chance babies in the womb do the same.

FAQ #6

What happens while babies sleep in the womb?

  • Babies in the womb have been reported by researchers as showing signs of a slower heart rate while sleeping, just like babies and adults both. In fact, researchers have used this information to determine when a baby is asleep in the womb and when the baby is awake.
  • Additionally, babies in the womb experience REM sleep, which means they are likely dreaming. We don’t know for sure, and it’s not likely that we ever will, but there are plenty of indicators that babies in the womb do dream while they’re sleeping.

FAQ #7

Does baby sleep inside womb even when outside factors may interfere?

  • Yes, although a baby’s sleep can potentially be interrupted by some outside factors. The normal movement of a mother as she walks and moves throughout her day should not affect a baby’s sleep in the womb, but loud sounds or too much jostling might.
  • When does baby sleep in womb if mom is very busy? For the most part, a busy mom and even a mom who stays active throughout her pregnancy will not have any negative impact on a baby’s sleep cycle within the womb. This offer takes a lot to bother a baby in the womb, since the child’s ears are still blocked and the baby is underwater. Therefore, normal activity and sound aren’t a problem.

FAQ #8

Do external factors like these affect a baby’s development in the womb?

They could. However, the mother’s health and the health of her surroundings make more of a difference on the baby’s development in the womb.


So does a baby sleep inside the womb? Did you learn something useful about your baby’s sleep schedule while still in the womb? It’s fascinating to think about what your child might be doing before they are even born, and many expectant parents spend a lot of time thinking about this—so you’re not alone!

How much does baby sleep in womb during the different months or trimesters? Although not much is known about a baby’s sleep during the early stages of development, it is known that babies sleep about 95% of the time in the womb near the end of the pregnancy. It is believed that babies may not sleep in the earlier stages, but rapid eye movement (or REM) can be observed in babies as young as seven months.

How long does the baby sleep in the womb when mom is awake? Does the baby’s sleep cycle affect mom’s? Yes, especially when the baby is bigger near the end of the pregnancy. Movement may wake up the expectant mother while she’s sleeping, so she may start to change her own routine to fit that of the baby. This experience varies, of course, depending on how active the baby is and how much of that movement the mother can feel, but it is highly possible that mom’s sleep schedule will start to revolve around baby’s even before the child is ever born!

When does the baby sleep in the womb? Do you feel like you know when your child is asleep? With the information outlined above, you should be able to tell more often. Of course, if you have any further questions or concerns, reach out to your doctor for more information.
