A baby’s long head shape, also known as a boat-shaped head, is mostly corrected by 3 months of age by improving the sleeping position. For babies with a long head shape, this can be improved by putting barriers on the top of the head while sleeping and keeping enough space on both sides of the skull. If the improvement of the head is not obvious after 3-4 months of age, it is necessary to go to the hospital for customization of the head orthosis. Before wearing this head orthosis, the head ultrasound and other related examinations are performed, and customization needs to be given according to the data, and the orthosis is similar to a helmet and requires 24-hour continuous wear. Most navicular heads have no significant effect on the baby’s intelligence and are mostly seen in normal births.
