What is the normal respiratory rate range for an infant?

• A. 12-20 breaths per minute
• B. 15-30 breaths per minute
• C. 20-40 breaths per minute
• D. 25-50 breaths per minute

Answer: (D)

Infants breathe much faster than older children and adults, and their rate can vary a lot even at rest due to metabolic needs and small airways. A normal resting range for an infant typically falls roughly from the mid-20s up to about 50 breaths per minute, with higher rates possible during crying or activity. The range of 25-50 breaths per minute best captures this typical variability and aligns with standard pediatric references for infants. When counting, do it for a full minute in a calm, quiet state to get an accurate measure, and note that rates persistently above 60 or pauses longer than about 20 seconds would be abnormal.
