Input: A two-year-old boy drowned in the bath after he was left alone for a short time with his brother while their mother fetched a pair of pyjamas, an inquest heard today. Zoe Warner-Simpson, 29, was faced with 'every parent's worst nightmare' after she returned from a trip to the bedroom to find her son Edward underwater, a coroner said. The toddler was rushed to Milton Keynes Hospital but he had already been left with irreparable brain damage after being starved of oxygen and he died a few days later. His parents, who have a four-year-old son Oliver and 11-week-old son Thomas, decided to turn off Edward's life support.Edward Warner-Simpson, two, drowned in the bath after mother left roomMother Zoe left them for a short time to fetch a pair of pyjamasToddler was rushed to hospital but died of brain damage four days laterCoroner ruled it was a 'tragic accident' and said no third party involvement
