How to solve the problem that the baby always sits with an arched back?

The solution for babies who are always sitting with their backs arched should be based on the different factors that cause their symptoms. If it is caused by poor sitting posture, you can change the bad posture or wear protective gear, such as spinal dysplasia need timely muscle training.
1. Poor sitting posture: Before 4 months old, the baby’s body is in an asymmetrical position. 4 months old, the body develops into a symmetrical position. With the extension of the spine of the body, the anti-gravity factor can be gradually controlled, resulting in the anti-gravity phenomenon of stomach upward and waist bending, thus appearing to be always arching the back.
This can be corrected by changing the bad posture or wearing protective gears. For example, when standing and walking, attention should be paid to lifting the head and stretching the shoulders backward naturally, so as to change the bad posture; or wearing orthopaedic belts, so that the passive posture can be changed into the correct posture, and the use of orthopaedic appliances can improve the posture of the bowed back.
2. Spinal dysplasia: the baby is too small, cervical spine dysplasia, and the spine is relatively soft, it is easy to sit with the old bowed back. At this time, the baby can do corrective gymnastics, lumbar and back muscle exercises, especially back stretching exercises to help inhibit the development of bowed back speed, long-term persistence of bowed back problems will be improved.
It is recommended that when the above methods are not effective, you can go to a regular hospital for examination to determine the severity of your baby’s condition. If bowed back is accompanied by physiological curvature of the spine, plastic surgery should be carried out in time.
