Question
A 100-day-old baby has not eaten anything for 45 hours and has not urinated. The baby’s mental state is good, and they are sleeping well during the afternoon nap and playing without any symptoms of a cold or discomfort.
Answer
According to your description, it is not normal for a 100-day-old baby to go without eating or urinating for an extended period. Long-term non-urination may indicate kidney function issues, such as urethral blockage or kidney stones, which can lead to poor excretion and, in severe cases, to self-poisoning. It is recommended to drink more plain water to promote metabolism, maintain adequate body hydration, and feed milk or sugared water appropriately.
