Olivia Kate Fraser nearly made a premature entry into the world as her mother went into labour whilst going for a walk. Even though they got home in time, she was diagnosed with a heart murmur at birth but quickly recovered to be reunited with parents Lachie and Chloe. But then Lachie was diagnosed with a brain tumour and although an operation went well he suffered a cerebral haemorrhage that left him permanently brain damaged. His mother Diana sent him to the States for treatment and after Chloe briefly tried looking after him on her own they moved back in with Irene.
