Pneumonia
Pneumonia is an infection occurring in the lungs. It can be triggered by either bacteria or viruses. Babies with pneumonia often produce phlegmy and wet cough, which would bring up yellow or green mucus. In addition, they can be very tired and exhausted. Treatment options depend on whether the condition is bacterial or viral. It is important to visit the doctor, particularly when your babies have a fever. The bacterial cause is often more dangerous.
