When will the baby's anterior fontanelle close? When will the baby's anterior fontanelle close?

Every step of the baby's growth concerns parents. Today, let's talk about the problem of the baby's anterior fontanelle. When will the anterior fontanelle grow well? This is a question that parents are concerned about. Today, let's talk about when the anterior fontanelle of a healthy baby closes.

When does the baby's anterior fontanelle close?

1. According to the latest research, it is normal for the fontanelle to close between four and 26 months. Because this is a statistical result among the population, some are early and some are late. When the child is only three months old, the fontanelle is only 0.6 cm. Although it closes a little early, it is still within the normal range.

2. As long as the premature closure of the fontanelle does not affect the head circumference, it is basically acceptable if the head circumference of a three-month-old baby can reach 40-44 cm.

3. We need to look at the child's head circumference, but current research has found that the early closure of the fontanelle is not directly related to the size of the head circumference, and a particularly small head circumference is often related to congenital microcephaly, which may have already manifested at birth. As long as the child's head circumference is not affected, you can ask the local health care doctor to measure the child's head circumference. If it is within the normal range, there is no need to worry.

4. Why does the child's fontanelle close quickly when it is relatively small? It may be related to the fact that the mother took a large amount of calcium during pregnancy and the child absorbed it better. The child will be four months old in one month. The 0.6 cm fontanelle is likely to close after four months. As for whether to supplement calcium or vitamin D, it should be judged based on the child's other conditions, and it is definitely not based on the fontanelle alone.

Front fontanelle closing time

The anterior fontanelle is regarded as a window to the baby's health. It is diamond-shaped and gradually ossifies and becomes smaller after 6 months. This window is closed when the baby is 1-1.5 years old. Under normal circumstances, if you touch the anterior fontanelle with your hand, it will feel flat and tensionless. If it is bulging, tight or convex, it means that the intracranial pressure is increased, which is seen in intracranial hemorrhage, meningitis, etc. If it is sunken, it is seen in extremely thin newborns such as dehydration or malnutrition.

If the anterior fontanelle closes early or is too small, it is seen in microcephaly. If it is too large or closes late, it is seen in rickets, cretinism, hydrocephalus, etc.

Therefore, parents should touch the baby's fontanelle frequently to know what is going on.

The anterior fontanelle should be closed when the baby is 1 to 1.5 years old. It is not normal to close it too early or too late. If your baby has bald spots on the back of the head, sweats a lot, cries easily and has convulsions when sleeping, then he is lacking vitamin D. Give him Icoxin supplements and more sun exposure, preferably from 9 to 11 am every day. If the baby has not yet teethed, then take calcium at the same time. And now you should add complementary foods to your baby, such as millet porridge, egg yolk, egg custard, chicken liver, tofu, rice noodles, biscuits, etc. The principle of adding complementary foods is from thin to thick, from less to more, from one to multiple. Don't add several new foods that your baby has not eaten at the same time. After adding a food, observe the baby. If there is no abnormal stool, vomiting or indigestion, you can safely increase the amount. Timely addition of complementary foods is very important for the growth and development of the baby. It also lays a good foundation for the baby to not be picky about food in the future, and the baby will be easier to feed in the future.

How to care for your baby's fontanelle

1. Do not use pillows that are too hard, such as mung bean pillows or sand pillows, as this can easily cause deformation of the baby's head and fontanelle. In addition, if you want your baby's head to be perfectly shaped, you should frequently turn him over and change his sleeping position. Babies like light, so if he is used to sleeping on one side, you can use light on the other side to attract him.

2. Protect your baby's head and pay attention to the furniture at home to avoid sharp corners that may hurt your baby's head. If your baby accidentally scratches his scalp, you should immediately disinfect it with an alcohol cotton ball to prevent infection.

3. When going out in the summer, make sure your baby wears a sun hat to prevent heat from penetrating through the fontanelle and causing heatstroke; when going out in the winter, you should wear a thicker hat to protect the fontanelle while reducing heat loss.

4. The fontanelle can be cleaned during bathing. Baby shampoo should be used instead of strong alkaline soap to avoid irritating the scalp and inducing or aggravating eczema. When cleaning, place your fingers flat on the fontanelle and rub gently. Do not press or scratch hard, and do not scratch the fontanelle with hard objects. If the "cradle crust" on the fontanelle is difficult to wash off, you can first steam it with sesame oil or refined oil and soak it for 2-3 hours. After the dirt becomes soft, wipe it off with a sterile cotton ball in the direction of hair growth, and then sprinkle with baby powder after washing.
