A child from one to three years old is considered

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

Answer: (B)

One to three years is the period when children are commonly labeled toddlers. This stage follows infancy, as kids learn to walk more confidently and explore the world with growing independence, while also rapidly expanding language and social skills. In contrast, newborn refers to the very early days after birth, and infancy typically covers roughly the first year. Preschoolers are usually considered to be around three to five years old, sometimes beginning at age three. So the range of one to three years lines up with the toddler stage, which is why that term fits best here.
