When Words Take Flight: Understanding Speech Milestones by Age (Typical vs. Delayed)







Introduction

Speech and language development are key components of a child’s growth. They allow children to express themselves, build relationships, and explore the world. While every child progresses at their own pace, understanding what’s typical—and when there might be a delay—helps caregivers provide timely support.
