When a baby is born, there is a soft area above their head, which is the fontanelle. Usually, it will gradually close during the baby's growth process. But some babies are usually completely closed by the age of 18 months, while others may not be able to close for a long time. So what if the fontanelle hasn't closed for 18 months?
What if the fontanelle hasn't closed for 18 months
There is a diamond shaped gap at the top of the baby's head, called the anterior fontanelle, measuring 2.5 cm x 2.5 cm (the line connecting the midpoints of the two sides), which gives a tactile sensation. The timing of the baby's fontanelle closing varies greatly among individuals, with most cases completely closing before the age of two. I don't know what the baby's current head circumference is. If there is an increase in head circumference and the fontanelle is still significantly larger, it is recommended to seek medical attention at the hospital and, if necessary, undergo CT examination to determine if there are any intracranial abnormalities.
The closure of the fontanelle is a window reflecting the development of the brain. If the fontanelle closes too late, such children may have hydrocephalus, rickets, and dementia; Failure to close the fontanelle in a timely manner can affect a child's intelligence. Suggest going to a regular large hospital for a check-up to see what the reason is.
When does the baby's fontanelle close
1. The fontanelle on the head of infants and young children usually closes between 12-18 months old. If the fontanelle is not fully closed by 18 months old, it can affect the child's intelligence.
2. Delayed closure of the anterior fontanelle can be seen in children with rickets, cretinism, and hydrocephalus; Premature closure of the anterior fontanelle is seen in children with microcephaly. The fullness and protrusion of the anterior fontanelle indicate an increase in intracranial pressure, commonly seen in children with meningitis and hydrocephalus; Depression of the anterior fontanelle, seen in children who are dehydrated, malnourished, and extremely thin.
3. There is a triangular gap in the occipital area behind the head, which is the posterior fontanelle. The posterior fontanelle is small at birth and some are close to closure, usually closing at 6-8 weeks
From the above, it seems that the closure of the baby's fontanelle is a very important matter. Whether it is premature closure or delayed closure, it is a bad thing for the health of the baby. So, if this situation occurs, the parents of the baby must take it seriously and go to the hospital as soon as possible to see what nutrients need to be supplemented.
