Developmental delay means a child is reaching milestones, like walking, talking or playing with others, later than expected. Down syndrome is a genetic condition that usually involves differences in learning and development, along with a range of health needs.
Every child is unique, and these children bring joy, determination and connection to their families. Early intervention and ongoing support can help them build skills and live full lives.
