After giving birth to a baby, many treasure mothers inadvertently find that the baby's forehead is jumping and feels soft with their hands. Experienced seniors or doctors will remind the mother who gave birth to the baby for the first time: this part of the baby is called the front halogen door, so pay more attention to it and close it when the baby is well developed. So how do you see if the front halogen door is closed?

Development of pre-halogen gate

The development of halogen door is a stage of cranial sound development in every baby. Halogen door is divided into pre-halogen and post-halogen. The halogen door is relatively small before and after the baby is born. When the brain and skull develop to 3-4 months, the length of the connecting line between the opposite sides of the anterior halogen door is 1.5-2 cm.

How to see if the front halogen door is closed?

Under normal circumstances, it is completely closed from one year old to one and a half years old. Whether the baby's front halogen door is closed properly, under normal circumstances, we can observe it with the naked eye, and we can feel that it was soft by touching it with our hands, and then it gradually hardened. The baby's front halogen door doesn't seem to be sunken, which means the baby's front halogen door has been closed.

Characteristics of front halogen gate

The normal condition of halogen door before the baby is born is two to four centimeters. There is no bone block in the sunken place, so it feels soft by hand. If you look closely, you will find that the left-open front halogen door is very fragile. You need to deal with this with your mother. Don't hit this part. When washing your baby's hair, you must also wash it gently. No scratching.
