Summary :
Developmental milestones track children’s growth across physical, cognitive, social-emotional, and communication domains from birth to age four. These indicators help caregivers understand typical progress, recognize challenges, and provide support. Early intervention enhances development, fostering independence, problem-solving, and essential life skills.
Development Milestones
Developmental milestones are key indicators of a child’s growth and progress across various domains—physical, cognitive, social, and emotional.
For children from birth to 4 years old, these milestones provide a framework for understanding typical development and identifying any areas where additional support may be needed. Here’s an overview of the major milestones for each age group within this range:
