On her first night of freedom, Kathleen Folbigg said her "face muscles hurt from smiling so much".
Now six months later from being pardoned and freed from prison in June, Folbigg's convictions have been quashed and she is a free woman.
After spending more than two decades in jail over the deaths of her four children, Folbigg has been acquitted — the NSW Court of Criminal Appeal quashing her convictions on Thursday morning.
As the decision was announced, applause filled the court.

It comes after an inquiry heard there was reasonable doubt about her guilt following new scientific discoveries.
In a final report released in November, inquiry commissioner Tom Bathurst KC found there was an "identifiable cause" for three of the deaths and Folbigg's relationship with her children did not support the case that she killed them.
The appeal judges agreed that the mother's diary entries — controversially used during her trial to help secure her convictions — did not contain reliable admissions of guilt. Folbigg consistently told police and a previous inquiry the entries reflected her feelings of failure as a mother after the deaths of three of her children.
