The first sign of pneumonia in children is usually an increased breathing rate, especially when the child does not have a high fever. For children under 3 months, more than 60 breaths per minute; for those aged 3-12 months, more than 50 breaths per minute; and for children over 1 year old, more than 40 breaths per minute indicate rapid breathing.
If a child has a fever and cough but is otherwise in good spirits, able to play, and loves to laugh, the likelihood of pneumonia is low.
On the other hand, if the child is lethargic, has bluish lips, is irritable, crying, or drowsy—especially if they sleep a lot—it may indicate a more serious condition.
