SHE was born weighing a mere 450 grammes and doctors thought each day would be her last.
But 10 months on and little Mackensie Blackmore has defied all odds after being born an amazing 15 weeks premature and spending the first three months of her life on a ventilator.
Mackensie also has the dubious honour of being the smallest baby to be born at the Countess of Chester Hospital and to survive.
Now safely tucked up at her home in Overpool Road, the tot still has ailments such as bronchitis and rickets, but is well on the road to recovery.
Not even contracting the MRSA 'superbug' infection could stop the little fighter.
And mum Laura, 22, whose other child, Taylor, was born 10-weeks premature, is amazed by her stamina.
She said: 'She was expected to be born at the end of April, but she was born after just 25 weeks on January 20.
'She stopped growing after 21 weeks and after being born at the Countess was transferred to a hospital in Liverpool where she remained until April 1.
'She was then transferred back to the Countess and was allowed home on May 28.'
Mackensie's condition was so critical that she was baptised as soon as she was born.
Laura said: 'The staff at Liverpool were sure that Mackensie wouldn't make it and thought that each day would be her last. But they were great and extremely helpful.
'She is now surviving on seven different kinds of medication. There are obviously complications, but she is doing quite well at the moment.'
Friends and family of Laura and her partner, Andy have been an immense help.
Laura added: 'I would like to thank my parents, Diane and Charlie, Nan and Grandad, Doreen and Dave, and all the staff at the Grace Arms who have supported us throughout.'
