Like most parents, they were thrilled their two-year-old had started walking.
But the occasion was also tinged with sadness – it is a milestone their eldest daughter Kaitlyn is yet to experience, despite being three years older than her sibling.
Kaitlyn, 5, was born with cerebral palsy diplegia, which effects the lower half of her body, and is unable to walk without a frame or walking stick.
“Seeing Kaitlyn’s face when Amber started walking was upsetting, she just wants to be able to play with her sister,” Mrs Gray said.
Such a scenario, however, may be possible thanks to a US hospital deciding the Reception student is the perfect candidate for potentially life-changing surgery.
“The surgery will aim to stop the cause of the spasticity and stiffness in her spine and the doctors are confident that independent walking will follow,” Mrs Gray said.
But the operation comes at a cost – the family needs $50,000 for the operation and the therapy that will follow while in the US.
