Why does the baby's fontanelle close late and how to deal with it

I believe every parent is very concerned about the baby's physical development. It is not required that the baby develops particularly well, as long as it is within the normal range. Then everyone must have heard of the fontanelle. The closure of the fontanelle can reflect the development of the baby's brain. Some people ask why the baby's fontanelle closes so late? And how to solve this problem? If you want to know the answer, take a look at what the editor has prepared for you next.

1. The fontanelle on the top of the infant's head usually closes at 12-18 months. The closure of the fontanelle is a window that reflects the development of the brain. If it has not closed after 18 months, it is too late. Such children may have hydrocephalus, rickets and cretinism. If the fontanelle is found to be closed abnormally, the baby should be taken to the hospital for further examination. In addition, when the baby sleeps on his stomach, his weight puts pressure on the bed, and the reaction force of the bed acts just on the child's chest. This pressure actually acts as a massage. After a period of exercise, the baby's lung expansion ability and respiratory muscle strength will be improved to a certain extent. Mothers should not force their babies to sleep in a certain way all the time. As long as the baby sleeps soundly, that is the best sleeping position.

2. Delayed closure and enlargement "Delayed closure" refers to the fact that children have not closed before 1 and a half years old. There have been cases where the closure has not been delayed until 3 years old. "Enlargement" refers to the fact that according to the above standards, the line connecting the midpoints of the opposite sides of the rhombus exceeds 2 cm.

1. Vitamin D deficiency rickets often causes abnormal calcium and phosphorus metabolism and changes in the body's voice quality. The changes in the head alone are very significant. Osteomalacia often occurs in the occipital bone and the center of the parietal bone. When you press lightly with your fingers, the bone sinks slightly inward, and it bounces back immediately after you release your hand. It feels like pressing a ping-pong ball with your hand, so it is called "ping-pong head." Symmetrical skull domes appear on the top of the forehead, making the head square. The fontanelle is too large or does not close until 2” or 3 years old. There is also delayed tooth eruption.

2. Cretinism, also known as cretinism, is caused by congenital hypothyroidism and general developmental retardation. In addition to being short, the head is quite characteristic, with a large head, a large and late-closing fontanelle, delayed tooth eruption, small and sparse teeth, edema-like face, low nose bridge, wide-set eyes, narrow palpebral fissures, swollen eye sockets, thick lips, a large and thick tongue, and drooling.

The above two points are the editor’s summary of why the baby’s fontanelle closes late and the corresponding solutions. You should understand more after reading them. In fact, babies at this age need more care and love, especially the fontanelle affects brain development, so it should attract more attention from everyone.
