When a child experiences the death of a sibling after a serious illness, their life will already have been greatly impacted. They will have lost so much already: time with their parents, normal family life and a relationship with a healthy sibling. Children will have observed how adults express their emotions or not. They will have learnt how grown-ups react to questions about their sibling. Maybe they will have been excluded from the truth or overwhelmed by too much information. Together with their age and developmental stage their observations and experience of their sibling’s illness will have all been setting the foundations for how they will grieve.
