My Son Is Now 16 Months Old But When He

My son is now 16 months old but when he was 6 days old he had a grand mal seizure and we found out he had a subdural hematoma. Later the doc said it went away but he kept on having what i believed to be seizures. He had a eeg that was said normal. He jerks real bad in his sleep sits up but more in a jerk way with his eyes open looking glazed over and i talk to him but he doesnt know it and then right back to sleep. It happens several times a night and several nights a week. I cant seem to get an answer on whats wrong with my son but i know something is not right. Please help us.
