The fontanel at the top of the baby’s head is usually the anterior fontanel, and its closure usually occurs 12 to 18 months after birth.
If the fontanel closes later than normal, it is a delayed closure of the fontanel and needs to be taken seriously. It may be caused by rickets, hereditary diseases such as congenital osteogenesis imperfecta, congenital skeletal malformations, cartilage nutritional disorders, etc.; endocrine disorders such as cretinism, dwarfism, and increased intracranial pressure.
If your baby’s fontanel is abnormal, it is recommended to consult a doctor in time, and need to be combined with the clinical symptoms for appropriate treatment.
