The sizes of fontanelles of different babies are different. The size of the baby's anterior fontanelle after birth is between 1.5 and 2 centimeters.

The human skull is composed of six bones. After the baby is born, the skull is not fully developed, so there will be gaps between the bones. There are two areas not covered by bones on the top of the baby's head and the back of the occipital bone, which are called the anterior fontanelle and the posterior fontanelle.

1. The sizes of fontanelles of different babies are slightly different. After a normal baby is born, the size of the anterior fontanelle is 1.5 to 2 cm, and it looks flat or curved. The anterior fontanelle usually gradually becomes smaller around six months after birth and closes between 12 and 18 months. There is a triangular posterior fontanelle at the back of the head, which closes 2 to 3 months after birth.

2. The baby's fontanelle lacks the protection of the skull, so it cannot touch hard objects before it closes. You can touch it gently with your hand or wash it. If there is a scab on the baby's head, do not pick it with your hands. You should soak it and then wash it gently. The closure of the posterior fontanelle indicates that the baby's head is very well developed and care should be strengthened at this time.

3. The daily care of the fontanelle mainly involves not using pillows with relatively hard materials for the baby, and trying not to let the baby maintain a sleeping posture to make the baby's head shape more perfect. It is good to turn the baby over frequently and change the baby's sleeping position. If the baby likes light and is used to leaning to one side, you can use another light to attract the baby's attention. Pay attention to the furniture in the home to avoid hurting the baby's head with hard objects.
