What is the term for children aged one to three years?

• A. Preschoolers
• B. Toddlers
• C. Infants
• D. School-age children

Answer: (B)

Age groups in early childhood have commonly used labels. For children aged one to three years, the term is toddlers. This designation sits between infancy (under one year) and preschool age (roughly three to five years). Toddlers are known for learning to walk confidently, exploring their surroundings, and beginning to speak in short sentences, while seeking more independence. That combination of mobility, language development, and growing autonomy fits the one-to-three-year window, which is why "toddlers" is the best fit. The other labels correspond to different age ranges: infants are younger than one year, preschoolers are typically three to five, and school-age children are about six to twelve.
