Question
Why do babies suddenly smile while sleeping?
Answer
Babies may smile during sleep due to night terrors, which can be caused by calcium deficiency. Symptoms of night terrors include sudden waking up at night crying or showing signs of fear. To determine the cause, it is recommended to undergo a blood trace element test and supplement the necessary nutrients according to the test results. In daily meals, you can increase the intake of calcium-rich foods such as fish and bone broth.
