A forty-six-day-old baby always cries when it's almost dark.

Patient's question:

It's been about ten days.

Doctor's answer:

In this case, consider vitamin D deficiency leading to low calcium and hyperexcitability as the causes. The child may show signs of crying, restlessness, and it is also important to check for abdominal distension. Pay attention to whether the child is well-fed. If there is abdominal distension, you can give the child Mimi Ai.
