Why do babies jump when they sleep?

The arrival of the baby has brought some changes to the life of the whole family. Everyone's focus begins to be on the baby, paying close attention to the baby's physical health and growth. When a baby first comes into this world, his body functions are very fragile and easily hurt. Therefore, dads are very worried about some situations of their babies, such as why the baby jumps while sleeping, why the baby's hands and feet suddenly jump while sleeping, etc., which makes parents very worried. So, why do babies startle when they sleep? Let’s analyze the reasons below.

In fact, babies startle while sleeping. This is a common phenomenon in the neonatal period. Medically, it is a physiological manifestation. The unconscious shaking of the limbs and body of the newborn is usually called startle. This behavior of the baby is due to the baby's self-protection reaction and protective behavior against the outside world. However, if the baby still often jumps or shakes his limbs when he is about five months old, you should go to the hospital to check his nervous system. Especially in winter, the baby is more likely to shake when exposed to cold, so you should pay attention to keeping the baby warm in winter.

The startle phenomenon in newborns is mainly due to the incomplete development of the neonatal nervous system, immature development of the cerebral cortex, high excitability of central nervous cells, and easy excitement due to stimulation. The nerve fibers of a newborn baby cannot fully form certain reaction conditions and are not fully developed, so the baby's limbs will twitch after being stimulated by a little sound. This is because the stimulation received by the baby cannot be transmitted to the brain for judgment like that of an adult, which causes shaking of the limbs. As the baby continues to grow, the various systems inside the body will gradually improve, and the baby will slowly be able to consciously face various situations. He will also be less sensitive to external sounds and will not even be frightened and cry when hearing sudden sounds. Also, the phenomenon of startling of the limbs will gradually decrease.

After reading the above explanation, parents may feel more relieved. Why do babies startle while sleeping? Most of the time, it is because the baby's nervous system is stimulated or stimulated by some kind of sound. So, as the baby grows and develops, the situation will get better and better, and parents don’t need to worry too much. Babies carry the hopes of the whole family. Parents should take good care of their babies and pay attention to their growth.
