Her heartbroken mum, Kimberley Lindop, described scenes of "chaos" at the hospital as doctors tried to save the baby's life. Minutes later, Polly suffered another cardiac arrest and tragically died at just 18 hours old. Kimberley described the ward as "chaotic", adding there were an "awful lot of people" in the unit when Polly suffered a "collapse". A post-mortem examination found the primary cause of Polly's death was sepsis and prematurity and that she had suffered severe lung damage. St Mary's Hospital told Sun Health it wouldn't be providing an official comment until the conclusion of the inquest.
