Hello docs. My daughter is 4.10 years old. From past 10 days her body jerk some while sleeping just like she put on electric shock. But this episode is happening just for some mili second. She jerk her hand sometimes or sometime her full body jerks in nap time and night time sleep. This episode runs in her full time of sleep cycle. It's happen both her REM sleep and non REM sleep cycle. Nothing was changed in her face or she is not drooling or neither crying or anything. Pls doctor tell me what is this. I am too much confused. And more worried about this
