What is the term for a child aged 1-3 years?

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

Answer: (A)

The term for a child aged 1-3 years is "toddler." This phase of development is characterized by significant physical and cognitive growth as children begin to walk, explore their environment more independently, and develop their language skills. During this stage, toddlers are also forming their sense of self and learning about social interactions. This is a crucial time for fostering independence and developing foundational skills that will support their future learning and development.

The other terms refer to different developmental stages: "infant" describes children from birth to around 1 year old, "preschooler" typically refers to children aged 3-5 years who are preparing for school, and "adolescent" applies to individuals aged approximately 12-18 years. Each of these stages represents distinct developmental milestones and learning opportunities, but in the case of 1-3 year olds, "toddler" most accurately captures the characteristics of this age group.
