What is on a Baby When it is Born?

What is on a baby when it is born? There are several factors that affect the skin of a newborn. The skin is often covered with fine hair, though this should fade after a few weeks. The newborn will also have a layer of vernix, a substance that protects the baby in the womb, which should wash off during the first bath. The skin may be dry and cracking at birth, but this should improve in time.

Vernix caseosa

In this image, a vernix-coated baby is clearly visible. The coating is characterized by its unique morphology, mobile architecture, and presence of antimicrobial polypeptides. The Vernix caseosa coat is composed of 41 proteins, 25 of which are novel to the Vernix. Three of the identified proteins are components of innate immunity, while two others have direct antimicrobial properties. Vernix coating may serve multiple functions in utero, including water barrier, temperature regulation, and innate immunity. This biofilm is also believed to aid in the transition of a baby from an intrauterine life to an extrauterine life.


During the course of labour, the newborn’s chest is compressed, causing meconium to accumulate in the lungs. This condition, known as meconium aspiration syndrome, can cause a baby’s airways to become obstructed, which can lead to infections such as pneumonia. During labour, the baby’s oxygen level is often low, but care providers will likely detect signs of distress before the newborn takes its first breath.

Skin-to-Skin contact

The benefits of skin-to-skin contact on a baby are long-lasting. During the first hour after birth, the baby’s body is in its most active phase, the “golden hour.” This is the time when the chemical connection between mother and baby is strongest, so medical professionals are more likely to allow skin-to-skin contact during this crucial time.


In the final weeks of pregnancy, mothers can express colostrum. This process is known as antenatal expression and has been recommended by some NHS Trusts. It can be started earlier in the pregnancy for mothers with multiples. This method is also beneficial for infants, ensuring that they start life free of formula supplementation. Scientific research has proven that colostrum contains essential immunological properties and helps colonise the baby’s intestine with healthy bacteria. Several studies have also suggested that colostrum may help protect a baby from disease and allergy.


A baby’s lungs start to develop in the womb between five and 16 weeks. During this time, they begin branching internally, creating a system of tubes, or bronchi, that connect with the windpipe. Each lung begins with two main bronchi. Other smaller branches are formed off of each main bronchi. The smaller branches become increasingly smaller as they branch out from the main bronchi. At the tip of each branch are tiny tubes that lead to the alveoli or respiratory sacs.


The first day of life is both exciting and exhausting. You may notice the new baby’s white skin and clumps of amniotic fluid, but you might not understand why. This coating has unexpected benefits.

Lanugo is a layer of downy hair that covers most of a newborn’s body before birth. The hair is not found on the penis, lips, or soles. It also does not grow on the sides of fingers and toes. It usually falls out within a week or two of birth. The hair has a physiological purpose. It serves as insulation. It may also be a sign of malnourishment or poor nutrition.
