5 Reasons Why Do Babies Sleep With Their Butt In The Air

One day, you wake up in the morning and see that your baby is sleeping with his face down and bum up. This posture is funny, but it shows up for a reason. Why do babies sleep with their butt in the air? Is this frog position dangerous? This post will answer all these questions and share with you some caring tips. Now, let’s get started!

Why Do Babies Sleep With Their Butt In The Air?

If you find your baby sleeping in this position, he may find it comfortable and feel like being cuddled. There are other reasons, such as muscle memory from the gestation period or crawling lessons he is trying to learn.


Many adults love to lie curled up to form a ball while sleeping, and so does your baby. The difference is that he prefers lying with his butts.

This posture doesn’t look comfortable to many people, but the child has an opposing idea. He finds himself comfortable sleeping like that.

This posture is low effort. Whenever your infant is ready for sleep, he doesn’t have to adjust his body too much to fall asleep quickly and comfortably.

Muscle memory

When your child’s motor skills have developed to the stage where he can control himself, he’ll typically choose the safest solution.

He finds this sleeping posture safe because he has been most familiar with it for nine months in the womb.

This posture becomes the standard for a newborn infant at the moment, and it’s typically why he gets uncomfortable when he’s not in this pose when he wakes up.

There’s no need to be worried about this frog position. Your child is trying to sleep as he did for a long time.

We call this habit “muscle memory”. Your kid will grow up and change to new sleeping positions. This habit may continue into adulthood, but we won’t notice it because it’s too subtle.

Crawling lessons

A baby’s muscles may be tight because they’ve been resting like a cocoon inside a uterus for nine months and haven’t been able to stretch.

Muscles grow as your kid gets older. The ligaments will extend and relax with time, letting them sprawl out in postures more similar to those seen in adults.

However, this stage lasts quite long. Before babies can adopt sleeping habits like adults, they prefer sleeping in the bum position.

Furthermore, your baby’s position while sleeping with their bottom in the air is very similar to the one they adopt when trying to crawl.

When your child learns to crawl, you may notice him on the floor with his limbs under him, moving from side to side till he works out how to move forward.

Feeling of being cuddled

Every child loves hugs, especially when tired and needs a place to rest. When you hold your baby in your arms, he often stays quiet and looks happy.

Some parents hold their babies until they fall asleep. When being cuddled, their baby legs press slightly into their stomach.

Even when they sleep, they keep this posture, making them look like a frog.

Common position

Many infants go through a stage where they like to sleep in this posture. Although not every child has this habit, it is pretty frequent among infants aged 6 to 12 months or older.

Parents may worry about this sleeping habit because it looks strange. However, it’s normal if your kid likes this frog position.

Please note that sleeping with the butt in the air is a common sign, showing that your child is growing up.

Is It Dangerous For Babies To Sleep In This Way?

If your child can’t turn over themselves, this posture is dangerous. However, even when he can adjust his body, this issue is not entirely safe.

When is it safe?

Sleeping with the butts in the air creates chances for your child to learn how to roll over. It’s time for him to develop the skill of rolling from back to belly and belly to back.

Then, he can work his way up to crawling and walking.

Moreover, your baby feels comfortable in this position. This habit prevents the risk of sleep apnea among kids.

If your baby rolls over on his own, you don’t need to adjust his sleeping position.

Babies eventually become strong enough to lie on their stomachs or sides, which is totally natural.

When is it dangerous?

You may have heard about SIDS, which is strongly connected with sleeping habits. If your baby can’t flip over, the issue will turn out extremely dangerous.

Although the newborn should be pretty safe once he starts to roll, crawl, and consider different postures, it’s still a wise option to get medical advice from your doctor.

How To Keep Babies Safe if They Roll On Their Tummy to Sleep?

It’s good news if your baby can flip over by himself. Yet, you should also take action to make sure that your baby is safe.

No pillows

Do not use pillows until your child turns two years old, as they cause asphyxia. Stuffed animals have the same risk despite how adorable they look.

As a result, keep the bassinet to your baby’s crib empty. Only allow their presence if you can monitor.

No blankets

We also mean “no blankets” when we mention the empty cot. The blankets can keep your child warm, but nothing is more important than safety.

You can use the sleep sack to cover your child’s body. The sack will give him warmth and comfort without posing any suffocation risks.

Use fitted sheets

If the sheets are loose, they will become another version of the blanket, increasing the risk of asphyxia. Hence, make sure to use sheets that can fit the crib tightly.

Frequently Asked Questions

Parents have a lot of concern when finding their children sleeping in the frog position. Here are some of their frequently asked questions.

1. At what age can your kids sleep on their stomachs?

There is no specific age or time that determines which age babies can sleep in this position. They do it when they can.

For the first year of their life, it’s vital to put the babies to rest on their backs. Yet, if your baby flips from back to stomach on his own at night, leave her there.

According to experts, babies at this stage have a lower risk of SIDS, which decreases substantially after they reach the age of six months.

2. Do babies sleep better in the frog position?

This position offers some benefits, such as helping your kids sleep more comfortably and learn how to crawl. However, if babies fail to flip over themselves, there will be a different story.

3. Do I have to flip my baby onto their back when they roll over?

No, after your baby has rolled over on his own, you do not need to flip him onto his back. It’s a sign that he is getting stronger if he sleeps on his sides or on his stomach.

Once the baby is mobile, he can totally push himself around and change his sleeping posture.

Physical activity in learning how to move independently is an essential part of your child’s development.

However, putting children to bed on their backs is a good idea because it is the healthiest posture to sleep in and lowers the risk of SIDS.

4. Why do newborns in incline sleepers perish?

At least 94 fatalities have been associated with incline sleepers. Due to their inability to lift their heads, newborns using sleep positioners risk suffocating after turning onto their stomachs. In the event that a baby’s face touches the soft cushioning, it may be difficult for them to breathe.


The most common reason babies sleep with their butt in the air is comfort. They may also learn to crawl or keep their habits during gestation time.

This habit is normal among infants. Sometimes, it’s a good sign for your baby’s development. Yet, when he can’t adjust his body on his own, contact your doctor.
