The head can be restored in infancy, but not in adults. If you are in infancy, the bone quality is soft, the bone gap is wide and there is fontanelle, so the shape of the head is easily changed by external factors, such as sleeping in one position for a long time, because the bone gap and fontanelle are not yet completely closed, if you adjust in time, the shape of the head can be recovered after sleeping off, avoid always sleeping in one position, otherwise it is easy to sleep off, tilting the head to sleep is easy to cause the back of the head to be low and flat, from both sides Sleeping with the head tilted back can easily cause the back of the head to be low and flat, and from both sides to sleep without flattening the back of the head. Often change the direction of the head during sleep. If you sleep from a certain direction for a long time or are used to a certain side, you can raise the pillow on that side so that your head does not deviate from the past, and you can recover even if your head deviates during infancy, within one and a half years of age. If you try to correct it in adulthood, there is no way to recover.
