What Is Sister Down Syndrome
Sister down syndrome refers to a sister of a person with Down syndrome. It is not a medical diagnosis but a family relationship term used in education, support groups, and sibling resources.
What Causes Down Syndrome
Down syndrome is caused by an extra copy of chromosome 21. This occurs at conception and is not caused by anything parents did or did not do during pregnancy.
Support for Sisters and Families
Sisters may need age-appropriate information, peer groups, and family counseling. Organizations such as the National Down Syndrome Society offer guides and local resources to help siblings understand and navigate their experiences.
