Why do Babies Sleep With Their Butts in The Air
As babies grow and develop, they go through many physical changes that can be both fascinating and adorable at the same time.
One of the most interesting and unique behaviors that babies often display is the tendency to sleep with their butts in the air. This quirky sleeping position has been often referred to as the “monkey pose,” and it can be seen in babies of all ages.

If you’re a new parent, you may have noticed that your baby often sleeps with their butt up in the air. It’s a common sleeping position for many babies, But why do babies sleep with their butts in the air? Let’s take a look at the possible causes of this particular sleeping position.
Reasons Why Babies Sleep with Their Butts in the Air
There are several possible reasons why babies sleep with their butts in the air. Here are some of the most common ones:
- Sleeping Curled Up Reminds Them of the Womb
Babies spent nine months curled up in their mother’s wombs before they were born. Sleeping with their butts in the air might make them feel more secure and remind them of that time.
- Baby Is Learning to Crawl
Babies typically start to crawl between six and ten months old. Sleeping on their stomachs with their butts up in the air helps them practice lifting their heads and pushing up with their arms, which are important skills for crawling.
- It’s Comfortable
Babies might just find sleeping with their butts in the air to be a comfortable position. They don’t have to worry about their limbs getting tangled up or feeling confined.
How to Keep Baby Safe If They Roll On Their Tummy To Sleep
While sleeping with their butts in the air can be a normal sleeping position for babies, it’s important to take some precautions to ensure their safety. Here are a few tips to keep in mind:
- Follow Safe Sleep Guidelines
The American Academy of Pediatrics recommends that babies sleep on their backs until they are one year old. This helps reduce the risk of Sudden Infant Death Syndrome (SIDS). Once your baby can roll over on their own, it’s safe for them to sleep on its stomachs. However, make sure they are sleeping on a firm, flat surface with no soft bedding, pillows, or toys that could suffocate them.
- Don’t Swaddle Your Baby
Swaddling your baby can help them feel more secure, but it’s not safe to swaddle them once they start rolling over. They need to be able to use their arms and legs to move around and push themselves up if they need to.
- Make Sure Your Baby’s Head is Elevated
If your baby is sleeping on their stomach, make sure their head is slightly elevated. This can help reduce the risk of choking and also make it easier for them to breathe.
Myths Surrounding This Child’s Pose
There are a few myths surrounding the position of sleeping with the butt in the air:
Myth 1: It Can Cause Bow Legs
Some people believe that sleeping with the butt in the air can cause bow legs. However, there is no evidence to support this claim.
Myth 2: It Can Cause Hip Dysplasia
Hip dysplasia is a condition where the hip joint doesn’t develop properly, and it can lead to arthritis and other problems later in life. Some people believe that sleeping with the butt in the air can increase the risk of hip dysplasia, but there is no evidence to support this claim either.
Should I be concerned about this behavior?
No, there is generally no reason to be concerned if your baby sleeps with their butt in the air. It is a common sleeping position among babies and is usually a sign that they are comfortable and feel secure. However, if your baby suddenly starts sleeping in a new position and seems uncomfortable or restless, it may be a sign of discomfort or a sleep disturbance and you may want to talk to your pediatrician.

Is it dangerous for your baby to sleep with their butt in the air?
No, it is not dangerous for your baby to sleep with their butt in the air. This position may be beneficial for your baby’s health and development. Sleeping on their stomach can put pressure on their face and obstruct their breathing while sleeping on their back can increase the risk of acid reflux. Sleeping on their side can also be problematic if they roll onto their stomach. Sleeping with their butt in the air, on the other hand, allows for easy breathing and minimizes the risk of acid reflux.
Is it normal for babies’ legs to twist while sleeping?
Yes, it is normal for babies’ legs to twist and turn while sleeping. Babies are still developing their motor skills and are not yet able to control their movements while they sleep. It is also common for babies to move around a lot while they sleep, and this can cause their legs to twist and turn. As long as your baby seems comfortable and can move freely, there is usually no reason to be concerned. However, if you notice that your baby’s legs are consistently twisted in an uncomfortable position, you may want to talk to your pediatrician.
Final Verdict:
It appears that babies sleep with their bottoms in the air for a variety of reasons. From the need for extra support and comfort to the instinctive position they take when seeking warmth, it is clear that sleeping with their butts in the air can be beneficial to a baby’s well-being. As parents, it is important to ensure that their environment is safe and secure and that their sleep position is comfortable while taking into consideration the natural tendencies of their babies.
