When will the baby's fontanelle close and what should I do if it closes prematurely?

The baby's fontanelle will close automatically after a period of time after the baby is born. However, many young parents do not know when the baby's fontanelle should close normally, but this is something that many parents must understand. In addition, some people have reported that their baby's fontanelle closed prematurely. Well, next I will explain to you when the baby's fontanelle closes and what to do if it closes prematurely.

Closing time

When a baby is born, there are four fontanelles, two of which are more obvious. The larger one is located on the top of the head, called the anterior fontanelle. The smaller one is located on the midline behind the head, called the posterior fontanelle. The posterior fontanelle usually closes around 2 to 12 weeks after the baby is born, while the anterior fontanelle will not be completely closed until the baby is 6 to 18 months old.

What to do if closure is premature

1. Consider craniosynostosis. If the baby's fontanelle closes too early, it may affect the shape of the skull. The fontanelle is the gap between adjacent skull bones, and the suture is the joint where adjacent skull bones are closely connected. If the suture fuses too early, the baby's skull shape will also be seriously affected. This situation is usually called craniosynostosis. If the fontanelle closes too early and the suture is normal, the baby's head can still maintain a normal posture.

Second, it is necessary to monitor whether the sutures are closed and whether the head circumference is growing normally. If the head circumference is growing normally, there is generally no major problem. If a mild thyroid cyst is accompanied by hyperthyroidism, it will affect growth and development and requires timely treatment. If it is not accompanied by hyperthyroidism, the impact is not significant, but regular check-ups are required.

3. It may be related to calcium deficiency. It is recommended to take the baby to the hospital to test trace elements first and formulate a treatment plan based on the results. Another thing is that the calcium supplement may not be absorbed or utilized well by the baby, which may affect the effect. Another factor is the season. If the sunlight is not sufficient, it will affect the absorption and utilization of calcium.

Well, the above is the specific content introduced by the editor about when the baby's fontanelle will close and what to do if it closes prematurely. I believe that after reading it, you should already know the correct time for the baby's fontanelle to close. If the baby's fontanelle closes prematurely, the editor still recommends that you take the child for a check-up.
