A child under one year old is categorized as an

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

Answer: (B)

In pediatrics, age groups are used to describe development and tailor care. An infant is a child from birth through about one year old. Neonate refers specifically to the newborn period in the first 28 days after birth. So, while someone under one year includes neonates, the broad, standard label for a baby in the first year is infant. A toddler denotes roughly ages one to three, and a preschooler is about three to five years old. Therefore, a child under one year is categorized as an infant. For clarity, a baby of a few days or weeks old would be a neonate, while a baby around six months old would be an infant.
