The child’s face is big on one side and small on the other, if the child is small in age, the problem of big and small face can be improved by adjusting the sleeping position, for example, if the child’s right side of the face is big, try to face the right side when sleeping, if the left side of the face is big, the child will try to face the left side when sleeping. If the child is used to sleeping with his face in one direction, parents should adjust the child’s sleeping position. When the child’s face is about the same size on both sides, parents should often change the child’s sleeping position, such as left-side, right-side, and supine positions. If the child is a little older face on one side is big and small, you can change the direction of chewing when eating to adjust the face, pay attention to the small side of the face with more chewing, adhere to a period of time after the face will be improved. At the same time, you can also try to sleep on the side of the big side of the face at night, for the improvement of the size of the face will also be very helpful.
