Symptom narrative

Mom was lying next to him in bed and noticed that he was shaking. Mom thought he might be cold and pulled a blanket on him. Lasted 6 seconds in total. Patient was sleeping at naptime later in day and started convulsing. Lasted less than 10 seconds. Legs were extended and upper arms were flexed. Eyes were closed. Did not pick him up or touch him until the shaking stopped. Patient was conversant with them immediately after the episode. By the time mom arrived, patient was in a chair. Seemed a little out of it, but that is normal when he wakes from a nap.
