Is it safe to touch my baby's fontanelle?

Yes, it's completely safe to touch your baby's fontanelle to monitor it. The part is covered with a strong protective membrane, but be sure to handle it carefully.

Do all newborns have uneven head shape?

Not all newborns have visible unevenness, but many do. Especially in the case of vaginal delivery, most newborns have an irregular shape after birth.

Can uneven head shape affect my baby's brain?

No, in most cases it doesn't affect brain development. The changes are usually related to the skull shape, not the brain.

Newborn Uneven Skull: Causes and When It Rounds Out

First-time parents often notice bulges or uneven areas on their newborn’s head, which can be concerning. According to Dr Jagadish Kathwate, Consultant Neonatologist & Paediatrician from Motherhood Hospital in Kharadi, Pune, these changes are usually temporary and harmless.

What Causes Uneven or Raised Areas on a Newborns Skull?

Uneven or raised areas on a newborn’s head can happen in both normal (vaginal) and caesarean delivery.

Common reasons include:

Soft skull bones: A baby’s skull is soft and not fully joined at birth, so it may look uneven
Pressure during birth: Even in a C-section, some pressure before delivery can shape the head
Swelling on the scalp: Fluid can collect under the skin, causing a soft bump that goes away in a few days
Small blood collection (cephalohematoma): A firm bump under the skin that may take a few weeks to reduce
Baby’s position in the womb: Staying in one position for a long period can affect head shape before birth
Soft spots (fontanelles): These are normal gaps between skull bones and may feel raised

Understanding Fontanelles (Soft Spots)

Infants have areas on their head called fontanelles. These areas are considered natural and help in proper development. The important features of fontanelles are:

At birth, the skull bones are not completely connected, resulting in soft areas
These soft areas allow the brain to develop fast during the first year after birth
The skull, however, hardens over time, as the baby develops
The partial closure of the front fontanelle is normally around 1 to 1.5 years of age
Parents should be aware that while gently massaging the baby's head, they can feel those fontanelles easily

How Long Does it Take for the Head Shape to Normalise?

A lot of irregularities or bumps tend to reduce after a few weeks following birth. At certain times, it may even take several months for the head shape to gain more uniformity.

“A baby's soft skull is designed to adapt, protect, and grow with time”

When Should Parents be Concerned?

Though skull changes are generally expected, some signs should be monitored. Parents should immediately visit a paediatrician if the following symptoms appear:

There is swelling in the head that seems to increase over time
The soft spot on the skull bulges during quiet moments
The baby has a high temperature combined with changes in the head
The baby is refusing to feed every time
The baby seems extremely lethargic or impossible to awaken
The baby repeatedly vomits
The baby doesn't have proper eye movements
The head shape is abnormally uneven and not improving over time
The uneven areas feel very hard and warm to touch

Importance of Regular Check-ups

Regular checkups are important to track your baby's growth and head shape in the early months. During these visits, the doctor checks the skull, soft spots, and overall development to ensure everything is progressing normally. Early monitoring helps identify any concerns at the right time.

These visits also give parents a chance to ask questions and get guidance on positioning, feeding, and care. Regular follow-ups provide reassurance and help ensure that any unusual changes are managed quickly and safely.

Does Your Baby Need Any Imaging Tests?

In most cases, imaging tests are not required, as doctors can assess head shape through a physical exam. If the swelling is large, increasing, not reducing after a few weeks, or linked with any symptoms like vomiting or poor feeding, the doctor may advise tests. An ultrasound scan is commonly used first, while CT or MRI scans are rarely needed for evaluation.

Practical Tips for Parents

Parents can facilitate the healthy reshaping of the skull by:

Changing the position of the head during sleep
Providing supervised tummy time while the baby is awake
Not keeping the baby in a single position for an extended period
Alternating sides while feeding or carrying the baby
Ensuring the baby sleeps on a firm, flat mattress without pillows
Avoiding long periods in car seats, swings, or bouncers

Bumps or uneven surfaces in a newborn’s head are quite common during the first few months of life. However, they should resolve on their own with time. Knowing the cause of these bumps will help you remain calm and take action appropriately. Make sure you properly care for your child, keep a watchful eye on them, and see a paediatrician regularly.

Why do Newborn Babies Have Uneven or Raised Skull Areas?

Newborn babies may have uneven or slightly raised skull areas due to the birth process, where soft skull bones overlap to ease delivery. These changes are temporary, and the head usually becomes rounder within a few weeks as the bones gradually settle into place.
