During the excitement of welcoming a newborn, parents often have numerous questions about their baby’s appearance, health, and development. One of these questions is about the belly button: “Why does my baby have an outie belly button?” While this may seem like a small detail, understanding the reasons behind different belly button types can help ease parents’ concerns. In this guide, we’ll explore everything you need to know about outie belly buttons, from their causes to how to care for them.
Understanding Belly Buttons
What is a Belly Button?
The belly button, or umbilicus, is a small scar on the abdomen resulting from the detachment of the umbilical cord after birth. During pregnancy, the umbilical cord connects the developing fetus to the placenta, allowing for the transfer of oxygen and nutrients essential for growth. Once your baby is born, the cord is clamped and cut, leaving a small stump. This stump eventually dries out and falls off, revealing the belly button underneath.
Innie vs. Outie Belly Buttons
When it comes to belly buttons, there are two main types: innies and outies.
What is an Innie Belly Button?
An innie belly button is a type of navel that is recessed into the abdomen. Most people have innie belly buttons, which can range from shallow to deep, depending on individual anatomy. An innie does not protrude and is often considered the “typical” belly button shape.
What is an Outie Belly Button?
An outie belly button, on the other hand, protrudes outward from the abdomen. This type is less common, occurring in approximately 10% of the population. While many parents worry when they see an outie on their newborn, it’s essential to understand that both types are perfectly normal and often do not indicate any health issues.
Comparison Table: Innie vs. Outie Belly Buttons
| Characteristic | Innie Belly Button | Outie Belly Button |
|---|---|---|
| Shape | Recessed | Protruding |
| Prevalence | Approximately 90% of people | About 10% of people |
| Health Implications | Generally no concerns | Usually normal but may require monitoring |

What Causes an Outie Belly Button?
The Healing Process of the Umbilical Cord Stump
After birth, the umbilical cord stump typically falls off within the first two weeks to three weeks. How the stump heals plays a significant role in determining whether the resulting belly button will be an innie or an outie. The healing process is influenced by various factors, including how the stump dries out, the baby’s position, and how the skin around the stump closes.
Factors Influencing Belly Button Shape
While the shape of the belly button largely depends on genetics and luck, several factors contribute to whether it becomes an outie:
- Healing Process: If the stump heals evenly, it is more likely to create an innie. If healing is uneven, it may result in an outie.
- Genetic Predisposition: Some studies suggest that belly button shape may run in families. If parents have outie belly buttons, there may be a higher chance that their children will too.
- Abdominal Pressure: Increased abdominal pressure from activities such as straining during bowel movements can influence belly button shape, potentially causing an outie to appear.
Common Myths About Belly Button Types
Many myths surround belly buttons, particularly concerning their appearance. Here are a few common misconceptions:
- Myth: Taping an outie belly button can turn it into an innie.
Fact: This method has no scientific basis and does not change the belly button’s shape. - Myth: An outie belly button indicates a health issue.
Fact: Most outies are entirely normal and do not require treatment unless associated with specific conditions.
Related Conditions
While most outie belly buttons are benign, certain medical conditions may cause them. Understanding these conditions can help parents identify when to seek medical advice.
Umbilical Hernia
An umbilical hernia occurs when a portion of the intestine bulges through the abdominal wall at the site of the umbilical cord. After birth, if the opening in the abdominal wall does not close entirely, it can result in a bulging belly button, particularly when the baby is straining.
Signs of Umbilical Hernia:
- Soft bulge at the belly button, especially during crying or bowel movements.
- No pain or discomfort for the baby.
Treatment: Most umbilical hernias resolve on their own by the age of 1 to 2 years. If the hernia becomes painful, swollen, or discolored, it’s crucial to seek medical attention immediately.
Umbilical Granuloma
Sometimes, a small red mass of scar tissue forms at the belly button after the umbilical cord falls off. This is known as an umbilical granuloma. It can sometimes release a yellowish fluid and may require treatment if it doesn’t resolve.
Signs of Umbilical Granuloma:
- A small, raised bump on the belly button.
- Possible discharge from the area.
Home Remedies: If an umbilical granuloma does not heal naturally, applying table salt can help dry it out, but consult your pediatrician for guidance on safe practices.
Is an Outie Belly Button Normal?
Prevalence of Outie Belly Buttons in Newborns
An outie belly button is not uncommon among newborns. In fact, statistics suggest that about 10% of the population has an outie belly button. While some parents may be concerned upon noticing an outie, it’s important to remember that variations in belly button shape are entirely normal.
When to Be Concerned
While most outie belly buttons are harmless, there are specific signs parents should watch for that may indicate the need for a doctor’s visit:
- Pain or Discomfort: If your baby cries when the belly button area is touched or seems to be in discomfort.
- Redness or Swelling: If the skin around the belly button is red or swollen, this could indicate an infection or other issue.
- Unusual Discharge: Foul-smelling discharge or a yellowish tint may signal an infection.
When to Call a Pediatrician:
If you notice any of the above signs, it’s essential to consult your baby’s doctor to ensure proper care and treatment.
How to Care for Your Newborn’s Belly Button
General Care for the Umbilical Stump
Proper care for your baby’s umbilical cord stump is crucial for preventing infections and ensuring it heals correctly. Here are some essential tips:
- Keep It Clean: Gently clean the area around the stump with a soft cloth. Avoid using alcohol or antiseptics, as they can irritate the skin.
- Air Exposure: Allow the stump to air dry as much as possible. If it’s warm enough, dressing your baby in just a diaper can help.
- Diaper Care: Fold down the front of the diaper or use diapers designed with a cutout to avoid contact with the stump.
- Avoid Pulling: Let the stump fall off naturally; do not attempt to pull it off, even if it seems barely attached.
Caring for an Outie Belly Button
Caring for an outie belly button follows similar guidelines as caring for an innie. The focus should be on keeping the area clean and dry. Here are some specific tips:
- Monitor for Changes: Keep an eye on the appearance of the outie and watch for any signs of discomfort, swelling, or discharge.
- Gentle Cleaning: If the belly button area needs cleaning, use a damp cloth, and avoid using cotton swabs that can irritate the area.
Debunking Myths About Outie Belly Buttons
Common Misconceptions
Outie belly buttons often attract various myths and misconceptions, which can create unnecessary worry for new parents. Here are a few common myths and their truths:
- Myth: Holding your baby too much can cause an outie.
Truth: Holding your baby has no impact on the shape of their belly button. - Myth: All outie belly buttons indicate a hernia.
Truth: While some outies may be due to an umbilical hernia, most are completely normal and harmless. - Myth: You can change an outie into an innie with certain techniques.
Truth: There is no scientific evidence supporting methods to alter a belly button’s shape.

Frequently Asked Questions (FAQs)
Can an outie belly button change to an innie over time?
While it is uncommon, some outie belly buttons may appear to change shape as a child grows and their body develops. However, the initial shape often remains.
Are outie belly buttons hereditary?
Yes, outie belly buttons can have a hereditary component, as belly button shape may run in families. If parents have outie belly buttons, there is a higher likelihood that their children might also have outies. However, it’s important to note that belly button shape is not solely determined by genetics. The healing process of the umbilical cord stump, skin elasticity, and other factors also play significant roles in whether a baby will have an innie or an outie.
Ultimately, while genetics can influence the likelihood of having an outie belly button, the final outcome can vary based on individual circumstances and the specific healing process for each baby.
