This time of year is always difficult for those who have lost a loved one, but for Melissa Mead and her husband Paul it is agonisingly so.
For it was in December 2014, with Christmas just days away, that their one-year-old son William – their firstborn and longed-for baby – died from sepsis after a catalogue of errors, misdiagnoses and missed opportunities to save him. As a result of the trauma Melissa and her husband were subsequently diagnosed with PTSD.
