What term describes a newborn from birth to one month of age?

• A. Infant
• B. Baby
• C. Newborn
• D. Neonate

Answer: (D)

In medical terminology, the term neonate specifically refers to a newborn in the first month of life. This neonatal period spans from birth to about 28 days, the time when a newborn makes the crucial adaptations to life outside the womb. That precision is why neonate is the best answer for describing a newborn from birth to one month. Infants generally refer to a broader age range (roughly from one month up to a year), and baby is a casual, non-technical term. Newborn is common speech for a very young baby but isn’t the precise clinical label for the first month, whereas neonate nails down that exact early-life window.
