Question
A one-month-old baby often tosses and cries at night. What should I do?
Answer
If a one-month-old baby frequently tosses and cries during sleep at night, it might be due to calcium deficiency. Full-term babies need to start supplementing 400 IU of vitamin D daily from 15 days after birth to promote calcium absorption. If supplementation is not timely, it may lead to symptoms of calcium deficiency, such as excessive sweating, restless sleep, easy to be startled, and baldness on the pillow. If these symptoms occur, it is important to go to the hospital for a check-up of trace elements to determine the severity of calcium deficiency and receive appropriate calcium supplementation treatment.
