Patient's question:
What are the obvious behavioral characteristics of Down syndrome babies? At what age can they typically sit independently?Doctor's answer:
Hello! Down syndrome is also known as 21-trisomy syndrome, which has a distinctive facial appearance that is usually visible at a glance. The bridge of the nose is low and flat, the eye fissure is wide, the ears are positioned low, the neck is short and thick, and both the hands and feet are also abnormal. It is recommended to visit a hospital for examination and, if necessary, undergo chromosome testing for a definitive diagnosis. Children with Down syndrome typically delay their ability to walk independently by 2 to 4 months compared to normal newborns.
