Hi, my 3 yr daughter started twitching in her sleep about a month back. It continues for about 15 minutes after she sleeps, and for an hour before she wakes up. Also once or twice in between. It looks like epilepsy but when she is awake, there are no symptoms. Around the same time she also started grinding her teeth, the intensity of which varies from night to night. Can you please let me know what I should do? Thanks
