Baby Development Milestones: Age-by-Age Guide

What are developmental milestones?

Developmental milestones are skills and behaviors that most children reach within a specific age range. These milestones cover different areas: motor, cognitive, language, and social-emotional. It is important to remember that every child develops at their own pace, and age ranges are approximate.

Not all children reach the same milestones

Age ranges are approximate; some children reach milestones earlier, while others do so later. Some children may not reach certain milestones at all. Every child is unique and develops differently. If you have any concerns, consult your pediatrician.
