Why do 30-day-old babies often stretch their limbs?

Patient's question:

No

Doctor's answer:

Hello, considering the possibility of calcium deficiency, which may manifest as pain, sweating, or spasms, a blood calcium test can help with diagnosis. Calcium supplements like Gai Zhong Gai can be effective, and it's recommended to consume foods high in calcium, such as fish and bone broth. Rest and proper nutrition are also important.
