the baby who died in poldark 's emotional season finale last night is a true survivor in real-life , having beaten the odds to live after she was born prematurely that little matilda fitt - who played baby julia poldark in the bbc drama - was born nine weeks early in their home town of barry , south wales , weighing just 2 lb 12oz .
matilda , now 21 months old , won the part to make her small screen debut only weeks after leaving the hospital , where she was treated for pneumonia .
she 's a very special person , extremely down to earth and just lovely - she was great with matilda .
