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

• A. Neonate
• B. Infant
• C. Toddler
• D. Preschooler

Answer: (A)

Neonate is the term for a newborn in the first month of life. This period, right after birth, is defined as the neonatal period, typically extending from birth through about 28 days. That makes neonate the precise label for a baby from birth up to the end of the first month.

Infant is a broader term that usually covers the early life stage beyond the neonatal period, generally from birth to around 12 months in many contexts. Toddler refers to children around 1 to 3 years old, and preschooler to about 3 to 5 years old. So the other terms describe later stages, not the first month.
