Parents of newborns have been warned about the dangers of "sleeping pods" after an infant died when left in one.
Leonidas Ramsden was found unresponsive the morning after being placed in a baby nest on his parents' bed at their home in Buckfastleigh, Devon, in April last year, an inquest has heard.
The four-month-old tragically died, with the coroner's hearing opened in Plymouth on Friday.
Now a charity has warned of the potential dangers of using the pods, whose rise in popularity in recent years has been attributed to their being used and advertised by so-called 'mummy bloggers' and influencers.
The Lullaby Trust, an organisation dedicated to researching sudden infant death syndrome (SIDS), says the pods shouldn't be used by babies under 12 months.
In an open letter to new parents, the Trust said: "Items such as cushioned sleeping pods, nests, baby hammocks, cot bumpers, pillows, duvets and anything that wedges or straps a baby in place can pose a risk to babies under 12 months.
"Evidence shows that sleeping a baby on anything but a firm, flat surface, or using soft, heavy bedding, can increase the risk of sudden infant death syndrome (SIDS).
"They can lead to overheating or potentially obstruct a baby's airway if they roll or their face becomes covered by loose bedding."
It's not known what brand of sleeping pod or nest Leonidas' parents had been using at the time.
The pods are widely available on Amazon and other baby product outlets, despite the youngster's death following similar tragedies in recent years.
In 2017, Tesco, Mothercare and other retailers pulled a range of the pods from due to safety concerns.
The year before, seven-week-old Grace Roseman died in a similar pod, the Bednest crib, which was branded a "hazard" for any baby too young to lift their head.
The newborn died of asphyxiation, an inquest heard, when her head got stuck on one of its fold-up sides.
The Bednest crib has since been removed from sale.
Leonidas' inquest heard he was "fed and placed in a sleeping pod upstairs on his parents' bed" on April 27 last year.
"In the morning, his parents checked on Leonidas and found him unresponsive," the coroners court heard.
The baby, who was was born on Christmas Day, 2021, was later pronounced dead.
A post-mortem was unable to ascertain Leonidas' cause of death although there are no suspicious circumstances.
A full inquest will be held at a later date.
