In a candid interview with The Times, Sarah exposed further details of life for herself and husband James Murray after losing eight-month-old Ella-Jayne eight years ago.
Describing the period as 'hell', Sarah admits that though a devastating experience she is proud of the work it has inspired their family to do.
Ella-Jayne was diagnosed with a hole in her heart while still in the womb and after being born five weeks premature she spent a month in intensive care. At eight months old Ella-Jayne tragically passed away. Now, the husband and wife team, who also have a six-year-old daughter Nell, hope to build a new hospital in her memory.
Sarah, 48, explains that initially it was hard for the pair to see the light at the end of the tunnel. The star described how she and her husband began to drink excessively, fearing they would drink themselves 'to death in the pub'.
That's when they took action and began to take as many positives out of their situation as they could. Their interest in charity work began after taking a trip to Cambodia, where they took part in hard labour for a month.
Sarah also revealed that she experienced one of the best moments of her life when Ella-Jayne had taken a full bottle, just hours before she passed away. 'Most people look at us like we're mad. "You found complete happiness watching a baby take a bottle?" But we did.
'It was one of the most joyous moments of my life. And it was only that joyous because of the hell we'd experienced prior to it.'
Sarah is opening up about her family's experience, revealing she wouldn't change what's happened to them as it's helping deliver a state of the art trauma unit which will help other families.
The actress and her husband, who she met on the set of Cutting It, say that every time a donation is made they think of their daughter and say, 'Yeah, well done girl'.
The unit needs £2million in funding, which will be raised by the Murray Parish Trust and the #2MillionSteps campaign. Funds currently stand at just over £28,000.
