“Alexander was a happy, healthy and very cheeky baby. He was a joy to have and then one day, at just 17 months old, my life was shattered when he died suddenly and unexpectedly.

“I don’t know why he died, but ground-breaking research projects like the one led by Professor Neil Sebire at Great Ormond Street Hospital mean I might one day be given an answer.

“That’s why I’m supporting The Big Give this year, which gives you the opportunity to have your donation doubled.”

Sudden unexpected death in infancy (SUDI) is one of the most common categories of infant death and around half of cases remain unexplained. Infection has been recognised as a possible cause of SUDI, but methods used to test for infection after death are outdated and the results are often unclear.

You can help fund a three-year long research project at Great Ormond Street Hospital that would use new techniques to investigate whether certain combinations of infection-causing bacteria are associated with SUDI, and whether the presence of these bacteria is related to known risk factors for SUDI, such as sleeping position or infant age.
