Question

A 6-month-old baby cannot lift its head, can roll over, and has normal appetite with no other obvious abnormalities. However, the baby sometimes trembles. Why does the baby suddenly cry during sleep?

Answer

A sudden cry in a baby could be a sign of rickets, with common symptoms including frequent crying, restless sleep, excessive sweating, and easy to be startled. Severe cases may result in bald patches on the pillow. You can supplement the baby’s calcium intake, such as calcium gluconate, by giving one dose per day, along with infant cod liver oil. The possibility of complications from a short-term high fever is small, and as the baby is not showing any different symptoms from before, there is no need for any checks.
