Head sizes in newborns and their norms

Immediately after birth, the baby is exposed to all kinds of procedures that are performed by neonatologists and nurses. Weigh, wash off mucus, blood, and measure the volume of the child's head. The last manipulation plays an important role, since it can tell a lot to doctors.

What should I know?

Almost all newborns appear in the world with a head swelling, called birth trauma. Sometimes moms themselves note that the baby on the 3-4 days outwardly changed for the better. In fact, the edema that formed during delivery was asleep. How does this happen?

When the hour of X comes and the woman realizes that it's time to give birth, the child is already beginning to make her way to the exit along the ancestral path, which is female genitals - soft tissues that are adjacent to each other. The kid has to literally push through them, and since he usually goes forward with the head, the main load and pressure lie on it.

Medical workers know that the swelling of the head is normal for a newborn, which ta

kes 2 days and does not require any treatment. Moreover, he is completely painless and the kid simply does not feel it.

Dimensions after birth

After birth, the head volume of a month old baby is approximately 34 cm, depending on the sex of the child. There is a small difference between boys and girls, manifested in the fact that the latter have a smaller circumference. Just a month, the head of newborns in size grows by 2.5 centimeters. In this case, the volume of the chest in a newborn is 2 cm less than the size of the skull.

At 3-4 months the volume of the head is equal to the size of the chest, the circumference of the first is approximately 40 cm. That is, the skull grows quite intensively - one and a half to two centimeters per month.

Newborn head
Usually the head of a newborn is several centimeters larger than the volume of the chest

Then the growth of the head slows down, the growth of the thorax comes to the fore. At the age of six months the volume is 43 cm, a month grows only one centimeter.

After six months a month, no more than 0.5 cm is added. Thus, at one-year-old age the head's volume in the child is about 47 cm.


Below are the indicators of normal growth in the table.

Table with the norms of the head circumference

However, it should be remembered that premature babies usually have slight deviations from the norm, which are expressed in reduced sizes.

Active growth in them is observed a little later than in normal children. Therefore, this table is just a sample of the classic head size growth in a baby, in fact everything happens individually.

Alarming signals

Of course, the growth of the body as a whole and its parts separately - it's personal, each child develops in its own way. However, there are certain standards that are well known to pediatricians and neonatologists, according to which there are symptoms of abnormal growth.

For example, if the head of a newborn rapidly increases in size soon after birth, this is a clear indication of progressive hydrocephalus. The disease is characterized by the fact that in the spinal canals a lot of fluid is formed, which "expands" the skull. With such symptoms, you should definitely see a neurologist.

When the size of the head is too small, there is mainly microcephaly, a diminished brain. Such a disease, at times, can be seen even on ultrasound during a woman's pregnancy. Microcephaly often serves as an excuse for termination of pregnancy for honey. Indications.

If the child's head volume is too small - consult immediately with a neurologist, as this is also a serious illness requiring complex treatment.

How is head size measured in children?

You can independently regularly measure the volume of a tiny head and record in a special notebook all the available measurements. For this procedure, you will need a soft tape with a clear separation by centimeters.

The child should be laid on the couch, sofa or on the table. It is important that the baby does not cry or shout at the time of manipulation, because the results obtained during the overexcitation of the baby may not be entirely correct.

Measurement is carried out on the eyebrow line. You simply put the tape on your head to the specified level and record the result. So you can monitor the growth status of your crumbs. If there are deviations, you will be the first to know about them and will be able to react quickly in a similar situation.

Do not worry, in any case, the symptoms of abnormalities are quickly manifested, and you will immediately see a violation in the growth of the head. It is much more important not to hesitate and urgently seek help from specialists.
