THE parents will never know what caused the death of their eight-week-old baby in his mother's arms.

An inquest has been told that doctors have been unable to discover the reason for Finley Milton's death.

Finley had enjoyed his first visit to a swimming pool in July last year before going to sleep in his mother's arms in bed.

An inquest heard that Finley, who had been born six weeks prematurely, was in bed with his parents and five-year-old sibling.

He woke at 2.30am for a feed and then fell back to sleep.

But when his mother, Kelly-Marie Taylor woke up at 5am she found the baby unresponsive in her arms.

Father Ben Milton gave Finley CPR as paramedics rushed to the family home, but the baby would later be declared dead at Musgrove Park Hospital, in Taunton.

A post mortem was unable to ascertain what caused his death.

Somerset senior coroner Tony Williams heard Finley was generally well and not on any medication.

After being taken to an indoor heated swimming pool the day before he died, Finley was given his feed and went to bed at 10.30pm.

Mr Williams said: "Mum fell asleep with the baby in her left arm.

"She woke at 5am and Finley was still in the crook of her arm.

"When she looked down Finley was unresponsive."

Mr Williams recorded a narrative conclusion saying the cause of the baby's death was "not determined".
