Some people may be very familiar with the fontanelle, so they pay close attention to its development when their baby is growing. Many parents are not very familiar with the fontanelle and do not understand its definition. When their baby reaches one and a half years old and their fontanelle is still not closed, they will be very anxious. So, what is the reason why the fontanelle is not closed when the baby is one and a half years old? Please refer to the explanation below.
What is the reason for the baby's one and a half year old brine door not closing
Under normal circumstances, the anterior fontanelle closes at the age of one and should not exceed 18 months at the latest. The closure of the fontanelle is a window reflecting the development of the brain. If it closes before 6 months, it indicates that the child may have microcephaly or underdeveloped brain. If it does not close after 18 months, it is considered too late, and such children may have hydrocephalus, rickets, and dementia.
The protrusion of the fontanelle indicates an increase in intracranial pressure, and children with this condition may have meningitis, encephalitis, and vitamin A poisoning. Children with a depressed fontanelle may have dehydration and malnutrition. If the fontanelle closes earlier, but as long as the head circumference is still long, there is no need to worry. If abnormal closure of the fontanelle is found, the child should be taken to the hospital immediately for further examination.
What should babies pay attention to when they are one and a half years old
1. Parents should frequently change the types and flavors of complementary foods for their babies to prevent them from experiencing anorexia and picky eating. This is a way to change their babies' anorexia and picky eating habits.
2. Moderate intake of protein. The baby's gastrointestinal tract is very tender, and the digestive organs are not fully mature, resulting in limited digestive capacity. Protein, as an important substance for building the body and performing physiological functions, can increase the metabolic burden of infants and young children if consumed in excess.
3. Exercise the baby's chewing ability. The baby's eating expression is becoming more and more firm, and their ability to chew food is becoming stronger. At this point, it is necessary to increase the variety of foods in the baby's menu to exercise their eating ability.
4. Develop good eating habits. Firstly, let the baby eat at a fixed time and place, even the table, chairs, dishes, and spoons they sit on should be fixed. In addition, when eating, it is necessary to move away things or toys that may distract the baby's attention, so that he can concentrate on eating.
5. Preventing and treating excessive nutrition in babies. Overnutrition can affect a baby's brain development and physical health, with obesity being the most obvious manifestation.
At the age of one and a half, it is the best time for babies to cultivate good eating habits. During this stage, parents should make their babies accustomed to a fixed habit in all aspects, forming an excellent foundation for their future growth. They can also take their babies for regular physical examinations to observe their growth.
