When she was born, 15 weeks premature and weighing ten and a half ounces, her father's confidence was about the only thing on Kimberly Mueller's side.
The size of a mobile phone: Kimberley Mueller weighed just over 10 ounces when she was born in Hanover, Germany - making her the world's smallest surviving baby
With a survival chance of less than 1,000 to one, every day she has got through since then is a triumph.
Kimberly was placed in an incubator for warmth, given a respirator to help her breathe and fed through a drip. She was also given a cocktail of drugs to boost an immune system that was barely formed.At three months, she faced a major setback, when doctors feared she could be blind. But laser treatment corrected the problem.
"Babies as small as this usually have no chance," said Dr Oliver Moeller, a heart specialist who treated her."We are incredibly lucky that she lived. Such a case I have never experienced. We had a lot of luck ... a lot."Kimberly is the smallest baby ever born in Germany and the youngest to survive. She was just 10.2 inches long and weighed little more than a packet of butter when she arrived in the 25th week of her mother's pregnancy.
Now six months, Kimberley has been allowed home for the first time (Above with mother Petra and father Andreas)
Petra Mueller, 38, who remained at her daughter's bedside in intensive care at the University Clinic in Goettingen, was allowed only to stroke her with her finger. "It was the nicest thing when she would grip my finger in her tiny hands," she recalled. "She was like a little bear gripping a tree trunk, just hanging on for life as if she was saying 'Don't leave me, mummy'."
