Newborn babies have many questions and no study guide. There are countless baby books out there, but almost not all of them feature a head circumference. circumference chart To find out how big your baby’s head is. If your pediatrician measures your baby’s head at every visit, you are going to Nobility Elementary, why do they do it?
How is the main circumference measured?
When you go to the pediatrician with your baby, the nurse or doctor will apply a soft tape measure around the baby’s head. Babies can cry with cold hands or worry if a stranger touches him or her, but this is never a negative. They make it agile and measure the size of the head. This is done on newborns up to two years of age. The fontanelle of the baby’s head is near at about 18 months of age, which slows down the growth phase of the brain. This means there is less need to measure.
Why measure?
The head circumference The fontanelle is measured to determine the growth and maturation of the baby’s brain. It is measured in centimeters and compared to the head. circumference chart . The chart It is stored in it. medical Submit it so that the doctor can see it:
- The circumference of the baby’s head as measured at the last visit
- the national average for children of that size, sex, and age.
The doctor can say that there is a problem with brain development if
- The head grows faster or slower than normal
- The head has an unnatural shape
- The baby’s head circumference It does not match the percentiles of length and weight
Head circumference graph
When you look at the chart This is a graph of age (in the direction of months) and measurements in centimeters and inches. There are areas that match the percentile spectrum. The physician places points on the graph. Anchor percentages apply:
- 5th percentile.
- 10th percentile
- 25th percentile
- 50th percentile.
- 75th percentile
- 90th percentile
- 95th percentile (average high).
At each visit, the doctor places a dot on the baby’s map.
To read the head circumference chart For boys, you continue a few months at the bottom. Take this line and go up and find the inches or centimeters and stop at this part. The percentile is in that section. Here is an explanation of the averages
- Newborns-95th percentile head circumference 39 centimeters or less. 5 – 5th percentile heads are within 32 centimeters.
- 3 months – 95th percentile head. circumference Approximately 43 centimeters; 5-5th percentile rises to within 38 centimeters.
- 6 months – 95th percentile head. circumference Approximately 46 centimeters; 5-5th percentile rises to within 41 centimeters.
- 12 months-95th percentile head circumference Within 49 centimeters; 5-5th percentile rises to within 44 centimeters.
- 24 months-95th percentile head circumference Within 51 centimeters; 5-5th percentile appears within 46 centimeters.
- 36 months-95th percentile head circumference Approximately 52 centimeters. the 5-5th percentile is within 47 centimeters.
To read the head circumference chart For girls, you continue a few months at the bottom. Take this line and go up and find the inch or centimeter and stop this part. The percentile is in that section. This is a comment on the average:
- Newborns-95th percentile head circumference about 38 centimeters. 5-5th percentile rises to within 32 centimeters.
- 3 months – 95th percentile head. circumference Approximately 42 centimeters. 5 to 5th percentile rises to within 37, 8 centimeters.
- 6 months – 95th percentile head. circumference Approximately 45 centimeters. 5 to 5th percentile rises to within 40, 5 centimeters.
- 12 months-95th percentile head circumference Approximately 47 centimeters. 5-5th percentile raises head to within 43 centimeters.
- 24 months-95th percentile head circumference Approximately 49 centimeters; 5-5th percentile will raise within 45 centimeters.
- 36 months-95th percentile head circumference Within 51 centimeters; 5-5th percentile appears within 46 centimeters.
Note that both boys and girls are not really about percentile. It is about seeing the steady growth of the head. circumference chart The field doctor simply observes how the baby’s head forms an upward bow as it gets older.
What does the main circumference indicate?
If the boys in your family have larger heads, chances are your baby will have it too. Genetics play a major role in the main volume. The physician ensures that the baby meets the percentile by showing or maintaining a certain number of centimeters or by seeing the value increase on the graph.
If the increase of two or more visits is higher than average, the baby’s doctor places a milestone against the measurement develops, and there is also the opportunity to attribute the abnormality to an illness he encountered not so long ago. If the baby seems fine, the physician can choose “monitor and wait” to see if the deviation continues until the next visit.
If there are abnormal readings during 3 or 4 visits, the physician can make the right choice.
- Above the 95th percentile – the physician should require an ultrasound or CT scan of the baby’s head to see if there is any fluid causing swelling or pressure in the brain. This is rare but can cause problems with lifting and developmental delays. Another major cause of more lifting is premature birth. Your baby is smaller than average at birth and can go through more “growth spurs” than the average baby because he is catching up. After this phase, the baggage is finally normalized.
- Below the 5th percentile – this can be a condition known as “failure to thrive”. This is when brain growth slows down via inaccessibility of caloric intake and the ability to eat caloric preparations. The lower the percentile of the head, the easier it is. circumference chart correspond to an even lower percentile in length and weight. charts Although it is very rare, a fairly low percentile in primary volume may indicate a natural malformation of the brain, the well-known asthma. As a rule, the baby’s brain undergoes a rapid developmental phase from birth to age 2, after which it slows down. With microcephaly, the brain is much slower.
