5 month old baby head circumference

After the baby is born, many new parents will pay special attention to everything about the baby. Any slight change in the baby will make the mother feel very surprised. During the baby's growth process, the mother will pay attention to the baby's head circumference, and sometimes she will measure the baby's head circumference herself. As long as the baby's body develops normally and the head circumference is within the normal range or has a little deviation, there is no problem.

How to measure the head circumference of a 5-month-old baby

We have said that the baby's head circumference refers to the maximum length of the head, so we should use a soft ruler to measure the baby's head circumference. Use a soft tape measure to wrap around the baby's head, passing through the middle of the eyebrows in the front and the most prominent point of the back of the head, which is the highest point of the occipital protuberance. The data obtained by going around the baby's head is the baby's head circumference. Generally, babies have less hair, so the thickness of the hair can be ignored. However, if the baby is older and has more hair, the hair should be parted for more accurate measurement.

What to do if your baby's head circumference is too small

A baby's small head circumference generally means that the baby's head circumference is smaller than the median head circumference of babies of the same age minus two standard deviations, or even below the third percentile. At this time, the baby's intellectual development may be restricted, and the baby will also lag behind in physical strength. Some may even have convulsions. These babies generally have small and pointed heads and narrow foreheads.

If it is determined after measurement that the baby's head circumference is small, you should go to the hospital in time to rule out some diseases. In addition, if conditions permit, you can do an intelligence test to see if the baby has intellectual defects. A comprehensive examination at the hospital can help your baby.

What to do if your baby's head circumference is too large

A baby's large head circumference means that the measured head circumference is larger than the normal value. This situation is generally caused by a certain disease. In clinical practice, it is found that the main cause of the increase in children's head circumference is hydrocephalus. Therefore, once the baby's head circumference is found to be abnormally large, and the head is obviously large and the body is small, then medical treatment should be sought in time to see if the baby suffers from diseases such as hydrocephalus and brain tumors, and treatment should be provided early to avoid causing greater impact on the child.
