Sarah Owen, 29, frantically called for help after finding five-months-old Noah and Charlie had stopped breathing yesterday morning.
Sarah, dressed in pyjamas, was seen holding the third brother, Ethan, in her arms in the street while fireman checked her house for carbon monoxide or a gas leak – cops have now ruled this out as a cause of death.
Detective Inspector Dean Taylor said: “At this moment in time, there is nothing to suggest that carbon monoxide poisoning was the cause.
“In fact, there is nothing that leads us to believe that this was anything other than a tragic accident.
“Inquiries are continuing in to what caused the young boys’ tragic deaths.”
The devastated mum has been told it could be a week before a post mortem test shows how her boys died.
“Sarah’s a single mum and lives there with the triplets who were her pride and joy” said a neighbor.
“She found Noah and Charlie dead when she got up on Saturday morning.
“She called for help and when no one came she dialled 999.
“The emergency services arrived and got her and Ethan out the house where she was screaming ‘my babies, my babies’.”
Family friend Anne Way, 64, went to help firemen carried the two infants from the house in Wildmill, Bridgend, South Wales.
She said: “She was totally distraught holding Ethan tightly to her chest.
“They wanted to take them both to hospital so I offered to take Ethan off her while she put her shoes on.
“But she shouted: “Leave my baby”.
“I saw the firemen carrying the two babies to the ambulances. They were like wax.”
“I’ve seen dead babies before from working in the hospital and they had been dead for hours.”
Retired hospital receptionist Mrs Way said: “That’s what no one can understand – how two of the triplets died and one survived.
“As far as I know they all slept in the same room.”
The godmother of the two boys set up a Go Fund Me page to raise money for funeral costs. As of Sunday afternoon donations had reached £3,700.
The gran of the two brothers who died this morning paid tribute to the “beautiful” tots during the “hardest day ever”.
Jane Owen took to Facebook yesterday to reveal her grief at the sudden and tragic loss.
Posting a picture of the smiling pair, she wrote: “Today I had hardest day ever to say goodbye to my most beautiful grandsons Noah and Charlie goodnight my darlings sleep tight till we meet again love u so much.”
The tots – two of three triplets named Noah and Charlie – were found not breathing when their mum Sarah went to check on them at her home in the Wild Mill area of the town.
The third triplet is understood to be in good health.
Officers arrived at the property after receiving a 999 call shortly after 10am yesterday morning.
Firefighters and medics were also in attendance at the scene.
The tots were rushed to the Princess of Wales hospital in Bridgend but were tragically pronounced dead.
The children’s godmother Siobhan Boyd has set up a GoFundMe page to support mum Sarah through the tragedy.
She wrote on the site: “Sadly this morning two of my beautiful godsons passed away”.
“I’m trying to raise money for their mother to help with the costs of flowers etc”
“If anybody would like to help hopefully we can raise enough to take the financial stress off Sarah at this difficult time.”
