Question

The newborn’s lips are a bit blue, and they eat and poop normally. Sometimes they are more blue, and sometimes they are better.

Answer

Hello, based on the situation you described, there may be two reasons: one is that the baby feels cold, and the other may be due to hypoxia. Both of these reasons can cause the lips to turn blue. It is recommended to keep the baby warm or use oxygen to improve the condition. This is usually a sign of hypoxia, and the symptoms should ease as the hypoxia improves.
