What is the head circumference of a 6 month old baby?

The head circumference of a 6-month-old baby is about 43 cm. As long as it is within a reasonable range, it is normal. Generally, the anterior halogen door of the baby is gradually calcified after 6 months, and it closes between one and one and a half years of age when the baby is one and a half years old.

Two. Each child has its own individual differences, and the situation at birth varies a lot, and there is no absolute standard of data. For example, some babies are born with 4 kilograms, and some babies are only kilograms when they are born, a difference of more than double.

When the two babies reach 6 months old, the indicators of physical development are still very different, and it is normal.

If the baby's halogen door is closed early, and the head circumference continues to grow, it will not affect the baby's development, but if the halogen door is closed early, the head circumference will stop and not grow, which will affect the baby's intellectual development. The depression of the halogen door is mostly caused by vomiting and diarrhea, and the bulge of the halogen door is due to high cerebral pressure, pay attention to whether the baby has encephalitis, meningitis, etc.

If the halogen has been closed for more than a week and a half, it is necessary to consider whether the child is deficient in calcium, vitamin D, rickets, or cretinism. It may also be associated with hydrocephalus. Therefore, once it is found that the closure of the baby's halogen door is delayed, it is necessary to go to the hospital as soon as possible for relevant examinations.

Hope these help!

Generally, the head circumference of the baby is about 44 at 6 months, the anterior fontanelle is normal, and the general law of the baby's anterior fontanelle closure is that the first 6 months will get bigger and bigger, and there are also baby anterior fontanelles that have been getting smaller. From 6 months onwards, it will get smaller and smaller. Usually one to one and a half years of age before the fontanelle is closed.

The head circumference of a month-old baby is 42-43cm. There are individual differences in the baby's head circumference, and it is also related to the accuracy of measurement, if you are worried about the abnormality of the baby, it is recommended to take the baby to the hospital for CT and other examinations.

2. The average head circumference of a normal full-term newborn is 33-34 cm, and the growth of head circumference in the first three months of the first month after birth and the growth of head circumference in the last nine months are equal (6 cm), that is to say, the head circumference of a one-year-old baby is about 46 cm. In the second year, the growth rate was 2 centimeters, and the head circumference of the two-year-old baby was 48 centimeters; A five-year-old baby's head circumference is about 50 centimeters. Measuring head circumference within two years of age is the most valuable, and of course the size of the head circumference is also related to the head circumference of the lead-deficient parents.

Small head circumference may cause brain dysplasia; A rapid increase in head circumference should rule out rickets and hydrocephalus.

The growth and development of each baby is a slow stage process, we can make a more reasonable judgment on the baby's development according to the baby's age, through the comparison of the data of each item checked with the normal range value. So, what is the standard for a 6-month-old baby's head circumference?

By comparing the size of the baby's head circumference, you can make a relatively simple major disease investigation of the baby's brain development, if the baby's head circumference is within the normal range, it means that the baby is relatively healthy.

At six months, the average head circumference of a baby boy is around the same level. In the case of a female baby, the head circumference development standard is about the same. Of course, this is only an estimated average range, not an absolute one.

Generally speaking, if the test results are too different from the numerical range, it may indicate abnormal brain development of the baby, and parents should pay special attention. If the self-test finds that the gap is too large, you should go to the hospital in time for relevant detailed examinations to ensure that the baby grows up normally and healthily.

Head circumference reflects the development of the brain and skull, although generally speaking, babies with fast head circumference are more intelligent and healthy, but the size of the baby's head circumference is also very related to the baby's height and parents' genetics, so parents can not simply judge whether the baby is smart by the size of the head circumference.

The phrase "the big head is smart, the small head is fine" is often said to be pleasing at both ends! New parents are keen to compare the size of their baby's head. In other words, the head circumference is the maximum length of the circumference around the head of the fetus.

When measuring the longest part from the front of the head to the back of the little guy, it is generally the length of a circle from the "base of the nose of the forehead" to the "occipital carina of the back of the head". Generally speaking, the head circumference of newborn babies is about 34 cm, and the baby's head circumference grows the fastest in the first 6 months, up to 10 cm! Among them, the growth in the first month can reach 3 cm, which is the fastest growth month.

Like the height of the person, the size of the baby's head circumference is actually different from person to person, generally in 2 standard deviations is considered normal, parents can not make a fuss about a little deviation from the standard.

Baby's head circumference standard refers to the normal value of the baby's head circumference, and the head circumference is the maximum length of the baby's head week, when the baby's head circumference is lower or higher than this standard, there may be some problems, let's take a look at the baby's head circumference standard within one year old.

Twelve-month reference table.

How to measure your baby's head circumference.

How to measure the baby's head circumference is the most accurate? We said that a baby's head circumference is the maximum length of a circle around the head, so we should use a soft ruler to measure the baby's head circumference. Use a soft ruler around the baby's head, the front through the middle of the eyebrows, and the back through the most prominent point of the back of the head, that is, the highest part of the occipital tuberosity, so that the data obtained by bypassing the baby's head for a week is the size of the baby's head circumference, generally the baby's hair is relatively small, so you can ignore the thickness of the hair, but if it is a big baby with more hair, the hair should be set aside to measure more accurately.

The head circumference is relatively large at birth, with an average of 33 cm, 39 cm in the third month, and an average of 45 cm at one year of age.

In the second year of life, the growth of head circumference slows down, and the head circumference is about 48 cm at 2 years of age;

Between the ages of 2 and 15, the head circumference increased by only 7 cm. The measurement of head circumference is most valuable within 2 years of age, which can show whether the child's central system development is normal or not, if the child's head circumference is too different from the above figures, it is recommended to go to the hospital for a check-up to reduce the occurrence of sequelae.

The size of the child's head circumference reflects the growth of the child's bones, and the head circumference of boys and girls is different, the range of head circumference for boys is about 43 centimeters, and the range of about 43 or 44 centimeters for girls is standard. A child's head circumference can reflect whether the brain is growing normally. Therefore, in daily life, we should pay attention to supplementing nutrition for children, such as using bones to make soup, which can supplement the calcium needed for children's bone growth; Promotes normal bone growth.

In this way, there is no fear of abnormal head circumference in children.

At 6 months of age, boys have a head circumference and girls have a head circumference.

According to the average head circumference of children at birth is 34 cm, to 46 cm at the age of 1 year, the growth of head circumference in the first 3 months after birth is equal to the growth in the last 9 months, and the head circumference at 6 months is equal to about 34 + 12 2 + 12 2 1 3 = 42 cm.

Six-month-old baby boys are about to between, with an average of between. The girls are approximately between to, the average is. Baby's head circumference is larger than the normal value, this situation is generally caused by a certain disease, in clinical practice found that the main reason for the increase in the child's head circumference is hydrocephalus, so once the baby's head circumference is found to be abnormally large, obviously the head is large and small, then you should seek medical attention in time**.

For toddlers of six months, boys have a head circumference in centimeters, with an average centimeter. The girl's head circumference is in centimeters, on average, centimeters. There are problems with head circumference that is too large or too small.

The head circumference of a 6-month-old child is about 36-39cm, and it is normal for a child to have a head circumference within this range at 6 months. If the child's head circumference is significantly smaller or significantly larger than this range, the corresponding cause should be found in time. There are pathological factors that can cause abnormal head circumference in children if they have hydrocephalus.

Tumors in the brain can cause a noticeable increase in head circumference. If the child has vitamin D-deficient rickets.

It can cause a square skull, and it will also cause a significant increase in head circumference, which requires timely intervention**, such as hydrocephalus to be surgically treated.

Generally speaking, the head circumference of a six-month-old baby is generally 25 to 28 centimeters.

You need to go to the community health clinic for a medical examination in 6 months, and he will have a range for you at that time.

The baby's head circumference is about 60 mm, and the three certificates are more than that.

If the head circumference of a six-month-old baby is concerned, the increase may be about 100 left centimeters.
