Patient's question:
Dear Director,I hope this message finds you well. I am writing to seek your assistance. My baby is now 67 days old. I have noticed that when she is lightly sleeping, her hands and feet are always moving, and she makes a clicking sound. When she is awake, she is also very active with her hands and feet. Additionally, she is easily startled. Everything else seems to be normal. Could you please tell me what might be causing this? Thank you.
Doctor's answer:
Based on the symptoms you described, it is considered that the child may be experiencing symptoms caused by vitamin D deficiency. Generally, it is recommended to supplement vitamin D (commonly known as cod liver oil) half a month after birth. The daily supplement should meet the physiological need of 400-800 units to prevent the child from developing rickets. Early symptoms of rickets include bald spots on the back of the head, excessive sweating, irritability, and difficulty sleeping. It is important to supplement promptly. If conditions permit, it is best to take the baby out for more than 2 hours of sunlight in the morning and evening every day. During sun exposure, the skin should be fully exposed to allow as much sunlight as possible to reach the skin to promote the synthesis of vitamin D!
