What it means
Developmental milestones are skills and behaviors that most children reach by certain ages, including physical (rolling over, walking), language (babbling, saying words), social (smiling, playing with others), and cognitive (problem-solving) skills. The CDC's milestone checklists give typical age ranges for each milestone — for example, most babies say their first word by 12 months. Missing multiple milestones may signal a developmental delay that warrants evaluation. Every child develops at their own pace, but significant or persistent delays should be discussed with your pediatrician so early intervention services can be offered if needed.
How to say it
