When does the baby's fontanelle close?

According to the editor's understanding, newborn babies generally have four fontanelles, which are like "skylights". By observing these "skylights", we can understand some of the baby's health conditions. However, the baby's fontanelle will not disappear. So, when will the baby's fontanelle close? Today, let me tell you the answer to this question.

The fontanelle usually closes when the baby is about 1.5 years old. If the fontanelle closes before 1 year old, it is easy to cause incomplete development of the baby's cerebellum or brain, which is a bad phenomenon. Some children's anterior fontanelles have closed when they are one year old, while some children's anterior fontanelles do not close until they are one and a half years old. This is normal.

The early or late closure of the anterior fontanelle reflects the development of the brain and the skeletal system. The normal time for children's anterior fontanelle to close is generally 1 to 1.5 years old. If it closes too early or too late, it should be taken seriously and the child should go to the medical care department for examination to determine whether it is abnormal. If the anterior fontanelle closes too early, you should consider whether the child has microcephaly, etc. If the anterior fontanelle closes too late, you should consider whether the child has calcium deficiency, hypothyroidism, hydrocephalus, etc.

Symptoms of abnormal baby fontanelle

1. Bulging fontanelle

The baby's anterior fontanelle is normally flat. If it suddenly bulges, especially when the baby is crying, and the fontanelle feels tight when touched, and the baby also has a fever, vomiting, or even convulsions, it indicates that the baby's intracranial pressure has increased. Increased intracranial pressure should not be taken lightly. It may be caused by intracranial infection, or it may be caused by symptoms of various diseases such as meningitis and encephalitis. You need to see a doctor as soon as possible for early diagnosis and early treatment.

2. Full fontanelle

1. If you find that your baby's anterior fontanelle is gradually becoming fuller, you should be alert to the possibility of a tumor in the brain, or fluid, pus, or blood accumulation under the dura mater. You must go to an authoritative hospital for diagnosis, timely treatment, and control the development of the disease.

The above is what the editor wants to introduce to you today about the closing time of the baby's fontanelle and some related knowledge. You can learn about it and I hope that the editor’s sharing will be helpful to you. In fact, the closure of the fontanelle is a normal condition for babies, and parents don’t need to worry too much.
