A year ago yesterday - when Summer Cowcher was born 16 weeks early - she weighed just 640g, her heart was visible through her translucent skin and her eyelids were fused shut.
Now with Summer celebrating her milestone first birthday, parents Ashley Cowcher and Natasha Watkins cannot believe the turn-around. "When you see her now, you wouldn't know what she's been through," Ms Watkins, 29, said.
Summer spent 10 weeks in an incubator at King Edward Memorial Hospital where she was repeatedly resuscitated, fought off infections and had six blood transfusions.
At four days old, her weight had plummeted to 530g and she could fit into the palm of her father's hand.
Now at home in Bunbury, Summer is getting stronger each day.
Her lungs are underdeveloped and she spends every night on oxygen but there is a lot of hope for the future."I'm excited about taking her to swimming lessons soon - it'll be great for her lungs," Mr Cowcher said.
