Sleeping jerks in children can be normal, or they can be epileptic or have a calcium deficiency. If the child is relatively young, it is most likely normal, and the twitching symptoms may disappear as the child grows older. Insecure children may also experience twitching in their sleep, so parents should give their children enough care and love to provide them with a sense of security. If it is accompanied by excessive sweating and occipital baldness, it is most likely to be caused by calcium deficiency, and you should take cod liver oil etc. in time to promote calcium absorption. If the twitching symptoms do not stop and the seizure occurs at night while sleeping, we should suspect whether it is epilepsy, and can confirm the diagnosis through electroencephalography. There may be other reasons for children to have twitching in their sleep, so it is recommended that they go to the hospital in time for a complete examination to clarify the cause of the problem and then give targeted treatment or therapy. All of the above medications should be used under the guidance of a doctor.
