The Appearance of the Babies Head at the Vaginal Opening

​By Laura Jana, MD, FAAP & Jennifer Shu, Dr., FAAP

Many parents have been mistakenly led to believe that all newborns are built-in pic-perfect, with pretty little circular heads. Permit us but say that for anyone who has gone through or volition experience vaginal delivery, it is nothing short of a blessing that a baby's skull is made upward of soft bony plates that are capable of compressing and overlapping to fit through the narrow nascence canal—a procedure referred to equally molding.

Shaping up

For some babies—such as those who "drop" well in advance of being born (in other words, settle themselves head first deep into their mother's pelvis well in advance of delivery), or those who must endure long labors and narrow birth canals—the result is often a newborn head shape that more closely resembles a cone than a nice round ball.

If you run your fingers over your newborn's skull, you may also detect that y'all can feel ridges along the areas where the bony plates of the skull have overlapped. In short, slightly misshapen heads are quite mutual right after birth.

Fortunately, over the side by side several weeks the bones of your babe'southward skull will almost convincingly round out and the ridges will disappear—assuming, that is, that your infant doesn't spend besides much fourth dimension on their back with his head in whatsoever one position. This is a common but easily avoidable cause for the development of a flat back or side of the caput known as plagiocephaly.

The soft spot

You will notice ane to 2 areas on your baby's head that seem to be lacking bony protection. These soft spots, referred to every bit fontanelles (anterior for the larger one in the front end, posterior for the smaller and typically less noticeable i in the back), are normal gaps in a newborn's skull that volition allow your baby's brain to grow rapidly throughout the side by side yr.

Many parents are agape to impact these soft spots, only you tin can remainder assured that, despite their lack of a bony layer, they are well protected from typical day-to-24-hour interval baby handling. Other things to know about the soft spot(s) include:

• In young infants, a sunken soft spot (when combined with poor feeding and dry diapers) can propose dehydration. Our advice to you: Don't read likewise much into this because it can exist a subtle finding or sometimes be present in normal babies. Instead, brand sure you have a good grasp on how to recognize aridity and check with your doctor if you have whatever concerns—with or without a sunken soft spot.
• In some instances, the soft spot on the elevation of your baby'due south caput may seem to be pulsating. There is no demand to worry—this move is quite normal and simply reflects the visible pulsing of blood that corresponds to your baby's heartbeat.

Bumps & bruises

In improver to molding, a fleck of swelling or bruising of the scalp immediately post-obit delivery is non uncommon for newborns. The swelling usually is most noticeable at the top dorsum part of the head and is medically referred to every bit a caput (brusk for caput succedaneum). When bruising of the head occurs during delivery, the effect can exist a boggy-feeling area, called a cephalohematoma.

Bruising and swelling are usually harmless and go away on their ain over the outset days and weeks, only can exist a contributing factor for jaundice.

Gone today, just pilus tomorrow

Sure, babies are sometimes born with full heads of pilus, but it's far more probable for them to be born with little to none. And those with hair today are likely to find it gone tomorrow. That'south because any hair your baby is born with is probable to thin out significantly over the next few months earlier ultimately being replaced with "real" hair. It is also entirely possible that whatever pilus your newborn does accept will change color by several shades and several times over their lifetime.
