She said medical staff couldn't give them an idea of how long she'd have to remain in Starship.
"We are by no means out of the woods and have an extremely long and rough road ahead."
She said Skyla had been keeping the paediatric intensive care unit and cardiac team on their toes.
Skyla was born with two major heart defects.
The defects weren't picked up during antenatal screening and were only discovered a few days after her birth.
Since she was born Skyla has spent more time in hospital than at home, and the family have set up a Facebook page, Support for Skyla, to help raise funds for all the extra expenses they're facing because of the long hospital stays.
Miss Craig has had to spend extended periods away from her partner, Shane Waters, and their three boys, Shalin, 9, Sam, 7, and Reyne, 5.
