Question
Over the past few months, my 5-year-old child has been experiencing unstable night sleep. They start crying and talking in dreams within 40 minutes to an hour, feeling very restless and grinding their teeth. What could be the cause of this? How should it be treated?
Answer
Based on the description, it is suspected that the child may have a calcium deficiency. It is recommended to conduct a detailed examination to confirm the specific situation. If necessary, consider supplementing with vitamin D or calcium, and taking cod liver oil orally at a preventive dose of 3 to 5 drops per day and a treatment dose of 1000 to 5000 units per day. For pure cod liver oil, only 1 to 2 drops are needed. Additionally, appropriate calcium supplementation is required.
