Patient's question:
When my son was 4 months old and breastfeeding, he occasionally had slight shaking or trembling in his head and arms. The trembling in his arms was similar to how adults shiver when they are cold, while his head would sway slightly from side to side at a similar frequency, lasting for tens of seconds.Doctor's answer:
Hello, full-term babies should start taking 400 units of vitamin D daily from the 15th day of life to promote calcium absorption. If supplementation is not administered on time, it may lead to symptoms of calcium deficiency.Suggestions: Excessive sweating, poor sleep, easy waking, and bald spots on the head are all typical signs of calcium deficiency. If these symptoms appear, it is important to visit the hospital for a trace element test to check for calcium deficiency and its severity. If calcium deficiency is confirmed, calcium supplementation therapy is necessary.
