Newborns are always waving their hands and feet when they sleep, most of them are a normal performance in the process of light sleep, but there are also pathological conditions. Newborns in the sleep process have alternating deep and light sleep, deep sleep newborns are more stable, but because of its growth and development stage is shallow, more sleep state, so it is easy to appear in this stage of a variety of actions, such as hands and feet moving, squeezing, smashing mouth and even crying. This is a normal physiological manifestation and will continue to improve as the child grows older. If symptoms are more frequent and accompanied by loss of consciousness, it is important to go to the neurology department of a children’s hospital for a video electroencephalogram (EEG) or a 24-hour ambulatory EEG to rule out the presence of epilepsy. If epilepsy is present, early treatment is needed.
