I. How to prevent habitual squint? 1, after the baby is born, we should pay attention to guide the baby to turn the head and change the direction frequently, especially when sleeping, the head should not always be biased in one direction. The position of lying down and rotating from side to side is beneficial to the symmetrical development of the baby’s neck muscles, facial features, face shape, forehead and back of the head, so as to avoid the asymmetrical closure of the front and back of the fontanelle, the size of the face and the asymmetrical development of the neck muscles in the future. 2. For babies with strong vomiting, when swinging the baby’s head to the side to prevent vomiting, you should also pay attention to the left and right rotation. How to detect myotonic squint (lumpy type and non-lumpy type) early? During the period from birth to 2 months of age, pay attention to the left and right sides of your baby’s neck to see if there are lumps. 1. There is lump type. This kind of lump is mostly round or oval, some are as small as a soybean, some are as big as a small fist; some feel soft like a lymph node, smooth and moveable, and some are as hard and immovable. In short, the appearance is more obvious. 2.Non-lump type. This type may not have obvious lumps, but can feel the affected side of the muscle from behind the ear to the clavicle is more rigid, compared with the other side is not soft, no elasticity. No matter how the position is fixed, the baby is obviously reluctant to turn to the side with the lump or stiffness, and the angle and magnitude of the turn are not large.
