Watching your baby grow is an exciting journey filled with firsts—first smile, first roll, first words. Knowing the top baby development milestones helps you understand what to expect and when. These milestones cover physical, cognitive, and social skills that signal healthy growth and development.
While every baby develops at their own pace, recognizing these key milestones can guide you in supporting your baby’s progress and knowing when to seek advice if needed.
What Are Development Milestones?
Development milestones are skills or behaviors that most babies achieve by a certain age. They show progress in areas like
-
motor skills (movement and coordination)
-
communication and language
-
cognitive abilities (thinking and problem-solving)
-
social and emotional interaction
Milestones provide a helpful roadmap, but remember, some variation is normal.
