Why do babies sometimes cry suddenly

Patient's question:

My baby is a premature child, and I was very worried about the child's condition from the beginning. Recently, the child has appeared with a series of situations, and I am also very worried, afraid that the child will become worse. Please ask why babies sometimes cry suddenly

Doctor's answer:

The reasons for a child's crying and fussing may be due to calcium deficiency and stomach pain, among other causes. Slight discomfort can lead to crying. Generally, the first approach is to supplement calcium and see if it helps.
The child is affected by neonatal diseases, so the mother must take the child to the hospital immediately for treatment. Avoid using medication blindly to relieve symptoms. For parents, it is important to pay timely attention to the child's condition and do their best to help the child receive prompt medical treatment.
