Developmental Milestones for a 2-year-old

Children usually progress in a natural, predictable sequence from one developmental milestone to the next. But each child grows and gains skills at his or her own pace. Some children may be advanced in one area, such as language, but behind in another, such as sensory and motor development.

Milestones usually are grouped into five major categories: physical growth, cognitive development, emotional and social development, language development, and sensory and motor development.
