In fact, after the baby is born, the little hands are basically clenched. This is not only a process of growth and development, but also a precursor to development problems. What is the secret of the baby’s little fist? Let’s start to reveal it now! Why do babies always clenched their fists? Why won\’t the baby\’s hand open, but even if it is opened, it will clenched instantly? This is because babies are immature and their flexor muscles are stronger than their extensor muscles. That is to say, because the baby is not fully developed, the force of stretching is weaker than the force of curling up. When a baby is about 3 or 4 months old, as the brain and nervous system develop, its self-control ability will be enhanced, and the flexor and extensor muscles will gradually reach a relatively balanced state. At this time, the baby\’s hands will not be so peaceful~ He will control his little hands to explore the world, and even when sleeping, he will hold them in a semi-empty state. However, for a period of time after the baby is born, it is considered normal for you to be able to open the baby\’s clenched fist hand and move it smoothly. If your baby is 6 months old and you can\’t stretch out your baby\’s little hands, or even cries because you stretch out your hands, or is unable to move, please go to the hospital for examination and early intervention as soon as possible. What\’s going on with the thumb adducting when making a fist? If some babies\’ thumb adduction is due to developmental delay, it can be corrected through massage and exercise. And because the disease causes the thumb to keep adducting, it will hinder the baby\’s fine motor development and must be corrected in time. Generally speaking, the adduction of the thumb will gradually disappear when the baby is 5 or 6 months old. If the baby still cannot straighten it after 6 months, it is likely that the nervous system is damaged, especially for premature babies, babies with hypoxia, Babies with pathological jaundice need to pay more attention to this situation. Parents should intervene in time when they find abnormalities, otherwise it will affect the baby\’s future motor development. The examination will be affected when the baby is crying. It is best to check when the baby is quiet. Why does the baby clench his fists and exert all his strength? It is a normal physiological phenomenon for babies to exert force occasionally. This is because the baby\’s brain nerves are not fully developed and cannot control muscle functions well. Movements that are not controlled by the cerebral cortex are unstable, uncoordinated and aimless, so the baby will involuntarily clench his fists and shake his body. With age and physical development, this condition will slowly improve and disappear. How to exercise your baby\’s little hands? 1.
