Geoffrey Toi's eight-year-old son, Christopher, is the only person in Singapore with a medical condition known as Bile Acid Synthesis Disorder, which puts him at risk of liver failure. Geoffrey shares how his family's hard-fought journey to secure lifelong support for Christopher has been greatly helped by the Rare Disease Fund, how he's learned to take it "one step at a time", and the sense of hope his family and community have given him.
