There is no single right approach, and it will depend on your child’s age, their temperament, and how much they already understand about what happened. What matters most is that the conversation is honest, age-appropriate, and leaves space for your child to ask questions — including ones you may not be able to answer.
Younger children often respond better to simple, concrete language. Explaining that their heart had a problem, that doctors fixed it, and that there is now something inside them to help keep it safe is usually enough to start with. Avoid medical jargon but do not be vague — children often sense when something is being withheld, and uncertainty can be more frightening than a clear explanation.
Older children and teenagers may have more complex reactions — anger, anxiety, grief about activities they fear losing, or concern about how they will be seen by friends. They may also research the condition online and encounter frightening information without context. Staying close to that process, and involving the cardiac team in conversations where helpful, can make a significant difference.
Siblings are often overlooked. They may have witnessed the event, may be frightened, and may feel that the family’s attention has shifted entirely to the affected child. A clinical psychologist experienced in paediatric cardiac conditions can help the whole family, not just the child who was ill. Ask your cardiac team for a referral.
