Little Eloise was only three weeks old when she was rushed to Starship for her first open heart surgery.
By 18 months old, she'd had three surgeries for her complex heart condition. Starship was a second home to Eloise, her parents Nadia and Leigh and her sister Caitlin.
Now Caitlin, 7, is sharing her special blueberry muffin recipe and baking muffins to raise money for Starship, as a thank you for saving her baby sister's life three times.
The keen baker is inviting all New Zealanders to join her on Starship's new campaign: Bake it Better for Starship, for a month of bake sales throughout July.
The bake sale is the quintessential Kiwi fundraiser and the two little ambassadors hope to see all Kiwis dusting their aprons and sharing their favourite treats, to raise money for a good cause.
