Now the people's living standards have improved, the quality of the whole people has been continuously improved, and more attention has been paid to prenatal and postnatal care. It is very necessary for the popularization of parenting knowledge. Recently, when the baby's forehead was closed, it attracted everyone's attention. Usually, the baby will close his forehead when he is one year old to one and a half years old, but the baby's feeding methods are different, the absorption degree is different, and the system is different, so the closing time is different.
The newborn's skull has two unhealed parts, called the anterior fontanel and the posterior fontanel. The rhombic space between forehead and parietal bone at birth is about 1.5-2 cm. After birth, the anterior fontanel became larger with the increase of head circumference, and gradually ossified after 6 months, and closed at the age of 1- 1.5 years. The posterior fontanel is a triangular space between two parietal bones and occipital bone, which is usually closed within 3 months after birth. If it is too late, you should go to the hospital for further examination in time to avoid delaying the normal development of your baby.
Usually, when a baby is one to one and a half years old, his forehead will be closed. If it is not closed at the age of one and a half, it is necessary to consider whether the baby is calcium deficient. Calcium deficiency is also one of the important factors leading to too late closure. You can check the trace elements for your baby and replenish them in time according to your physical needs, so as not to delay your baby's development.
If the baby's closing time is too late, it is suggested that besides trace elements, bone mineral density and alkaline phosphatase should be checked, and head CT examination should be done if necessary, so parents must always observe the baby's every move and never cause unnecessary harm.
Then, through the above introduction, we now know when the baby's forehead closes, and also know the reason why it doesn't close too late. It can be seen that it is very necessary to rely on parenting knowledge, and at the same time, it is necessary to be very careful in the process of taking care of the baby, not only to give the nutrition needed for physical growth in the diet, but also to create a healthy growth atmosphere for the baby.
