Question
My baby is 13 months old and has been weaned for half a month. They always cry at night. What should I do?
Answer
Before weaning, the baby should start supplementing 400 units of vitamin D on a daily basis from the 15th day after birth to promote calcium absorption. If supplementation is not done on time, it may lead to symptoms of calcium deficiency, such as excessive sweating, restless sleep, easy to be startled, and baldness on the pillow. Once these symptoms appear, it is important to go to the hospital for a check-up of trace elements to determine if there is a calcium deficiency and its severity. If diagnosed with calcium deficiency, calcium supplementation treatment is needed.
