Question
Why do children have unstable sleep at night, easily wake up, and experience limb movements?
Answer
Children may have unstable sleep at night due to several reasons, including a lack of trace elements, being too hot or too cold, excessive dryness, nasal mucus, or being overly excited before bedtime. If there is a calcium deficiency, it may lead to poor closure of the baby’s fontanelle; if there is a zinc deficiency, it may cause purulent sores around the corners of the mouth. Solutions to these problems include ensuring the baby receives adequate calcium and vitamin D and calming the baby down about half an hour before bedtime to avoid overexcitement.
