It's Heart Kids Awareness Week this week, collectors will be out in the street this weekend, raising money for the babies born - 12 every week - with a congenital heart defect.
These children often need multiple surgeries and they can only happen in Auckland.
Three-year-old Luna Clark is one of those children. She's just had her fourth open heart surgery. Her mum Olivia is at hospital with her but has taken a moment to join us to describe what life is like with a sick baby.
