A one-month-old baby cries urgently with urination, needing to go two or three times in one go. What could be the reason?

Patient's question:

No

Doctor's answer:

Consider vitamin D deficiency leading to low calcium and hyperactivity as possible causes. Children may exhibit crying, sleep disturbances, excessive sweating, and other symptoms. For normal full-term newborns, preventive supplementation with cod liver oil or other vitamin D preparations can be started from day 15 postpartum to prevent calcium deficiency.
