Why does the baby always stretch their arms and legs at night and can't sleep peacefully?

Patient's question:

Baby is two and a half months old

Doctor's answer:

Hello, if the baby lacks vitamin D, rickets caused by calcium supplements can lead to symptoms such as excessive sweating, bald spots on the head, night sweats, and skeletal deformities. It is recommended to visit the children's health care department for timely examination and treatment based on the condition, and to get more sun exposure.
