Why does the baby need to cry for two or three hours every day before sleeping?

Patient's question:

No

Doctor's answer:

Hello, it seems to be a symptom of calcium deficiency. It is recommended to take Gluconate Calcium Oral Solution (a brand called Sanjing) for treatment. It is necessary to have the baby undergo a trace element examination. At the same time, regular exposure to sunlight can promote the transformation and absorption of calcium.
