Many people say that the closing time of the halogen door is 18 months. Once this time has passed, many parents are worried about why the baby's vaginal door is not closed yet? I worry about whether the baby is deficient in calcium or whether there is a problem with brain development.

Generally, parents think that babies have only one bronchi located above the forehead. In fact, babies have several types of bronchi: lateral blubber, posterior blubber, and bronchiectasis. Generally, the bony and posterior bony joints have closed when the baby is three months old. The one that closed relatively late and received widespread attention is the bregma.

Concerning the front door, I often hear many parents say that the door is extremely soft and cannot be touched. It's like if the door is not closed, the child's brain is not protected. Some people say that children who touch the bluish door will become mute, while others say that if the bluish door is too large, it means that the child is deficient in calcium and is prone to rickets. Therefore, many of our parents generally hope that their children's urethra can be closed as soon as possible.

But in fact, compared with the cautious 18 months of the Chinese people, the closing time of the baby's vagina is generally considered to be 18 to 24 months internationally. Moreover, the baby's urethra is not as fragile as imagined. You must know that in addition to the skull, there are 80% of tissue underneath this location. If you try to press it with your fingers, it will damage the brain, which is actually very difficult.

In fact, if the halogen door closes prematurely, it is also a bad phenomenon. The reason why there is a gap like the blumen gate is because our brain needs room for growth. If the blumen gate is closed too early, it will limit the development of the brain.

Rather than paying attention to when the baby's lumbar gate closes, we should pay more attention to the growth of the baby's head circumference. You can judge whether your baby's brain development is healthy by looking at your baby's head circumference growth curve. The specific measurement method is the five-point positioning method: the highest point of the two eyebrows, the points corresponding to the ear tips on both sides, and the most prominent point on the back of the head. This is the most accurate measurement of head circumference.
