Generally, the best time to correct the head shape of an infant is before 6 months of age. This is because the skull is not completely hardened at this stage and is highly malleable, making it easy to make corrections. Infants within 6 months of the skull is softer, the bone seam is not completely closed, the head is easy to be deformed by external forces, so this stage can be corrected by changing the infant’s sleeping position, feeding posture, etc.; and after 6 months of infants’ skull is more hard, it is usually difficult to carry out the correction of the head shape. Generally smaller infants can be corrected and prevented from abnormal head shape by alternating sleeping positions such as left lateral recumbency, right lateral recumbency, and lying flat, while infants who have reached the age of 3 months can choose to have their head shape corrected by fixed pillows, but it is not advisable to use higher pillows. It is important to note that it is necessary to consult a doctor to exclude abnormal head shape caused by diseases, and the primary disease should be treated under the guidance of the doctor.
