Newborn limb tremor

Neonatal neurodevelopment is not yet mature, and the spinal cord of nerve fibers is not completely green, so "insulation" is poor. When a certain nerve is stimulated, the excitement can be transmitted to adjacent nerve fibers at the same time and cause a short-term "short circuit" phenomenon. Even a slight stimulus may cause the baby's obvious hands and feet to shake. As the baby grows, the nervous system continues to develop, the jujube film is gradually improved, and the "insulation" function is correspondingly improved. Generally, this phenomenon will slowly disappear after the baby grows to 4-5 months.
