THE parents of little Jack Dunn face the agony of never knowing what killed their baby.
Natalie and Stephen Dunn’s son was cruelly taken from them at just 16 months old in October 2009.
Since then the couple, who are expecting their second baby in June, have been searching for answers over what took his life.
Medics have been trying to find the cause of death, with tests being carried out by specialists in Birmingham.
But the couple, of Plains Farm, have just been dealt the devastating blow that they may never find out the cause behind Jack’s death.
Despite this, they have pledged not to give up the fight for answers.
Natalie, 21, said: “All of the test results have come back negative. We were waiting for this last one and I really don’t know what happens now.
“I don’t know if there are any more tests that can be done, but we are never are giving up hope.
“I hope that one day we will find out what happened. A child doesn’t just die.”
Little Jack was born healthy on June 6, 2008, but at three months he became poorly and stopped putting on weight. He was also constantly being sick.
Jack was admitted to Sunderland Royal Hospital where it was found his immune system was failing. He was then transferred to Newcastle General Hospital where he had a feeding tube fitted.
A scan revealed Jack’s brain was not growing and a few weeks later Natalie and Stephen, 25, were told the illness would eventually take their son.
The couple wed within weeks so Jack could be at their wedding but on October 7, 2009, he died.
In December the couple received the news that Natalie was three months pregnant and their baby boy, who they plan on calling Brenden Lee, is due to be born on June 7.
Natalie said: “We are absolutely over the moon to be having a baby boy and the pregnancy is going really well.”
Natalie, Stephen and their family are holding a fund-raiser to get a plaque erected at the hospital in Jack’s memory. It will take place on Saturday at the Willow Pond, Hylton Road, from 7pm to 11.30pm. There will be a disco, buffet and raffle.
