Question
How to handle nighttime sleep disruption in young children with intermittent mild hand and foot tremors?
Answer
From 15 days after birth, young children should take 400 units of vitamin D daily to promote calcium absorption. If this is not done on time, it may lead to symptoms of calcium deficiency, such as excessive sweating, restless sleep, easy to be startled, and bald spots on the pillow. When these symptoms occur, it is timely to go to the hospital for a trace element examination to understand the extent of calcium deficiency. If calcium deficiency is confirmed, then calcium supplementation treatment is needed.
