Lindsay Clancy's ex-husband struggled to compose himself as he spoke about his children on the witness stand in the murder trial over the deaths of the three youngsters. Clancy's former husband Patrick took the stand to testify for the prosecution to answer questions about his previous marriage. He is also a witness for the defense.Clancy, who has pleaded not guilty, is accused of strangling their kids – five-year-old Cora, three-year-old Dawson and eight-month-old Callan – using exercise bands while her ex-husband collected takeout food in January 2023.The defense will argue that Clancy, a former labor and delivery nurse, is not criminally responsible for the killings as she suffered an acute episode of postpartum depression and psychosis at the time of their deaths.The Massachusetts mother had been prescribed thirteen different psychiatric medications in the months leading up to the tragedy. Prosecutors argue the killings were deliberate and premeditated. After the murders, Clancy allegedly attempted to take her own life by cutting her wrists and neck before jumping from the second-floor window of the family's Duxbury home.Clancy survived but was left paralyzed from the waist down and now uses a wheelchair.Follow the Daily Mail for more updates...

Postpartum psychosis affects one to two of every 1,000 births in the US, or 0.1 to 0.2 percent. Unlike postpartum depression, which comes on gradually and can last for years, postpartum psychosis is a sudden psychiatric emergency.In postpartum psychosis, mothers lose touch with reality, suffering hallucinations, mania, paranoia and rapid mood swings. In many cases, like Clancy's, hallucinations and delusions can tell mothers to hurt themselves or their babies. 'It carries the most risk of the mother harming the baby due to having psychotic experiences,' says Dr Rod Hoevert, clinical and forensic psychologist and assistant professor at Maryville University in St Louis.There isn't one single trigger of postpartum psychosis. It can be brought on by a combination of severe sleep deprivation, drastic hormone fluctuations and a history of mental health conditions, especially bipolar disorder. Rachel H Tribble, a licensed clinical social worker in Florida who works with postpartum parents, told the Daily Mail: 'Any woman with a history of depression, anxiety or other mental health condition could be at higher risk.' 19:1619:10Court is adjourned for the dayCourt abruptly adjourned for the day as Patrick Clancy began discussing the day of the murders.
