Parents have described their heartache after their three-month-old baby was found unresponsive in her cot and died in hospital.
Kasey-Leigh Enos was said to be well-nourished and happy and her development was normal, an inquest into her death heard.
Her mum Charlene found her face-down and not breathing at the family home in Trent View, Knaith Hill, near Gainsborough.
The baby's uncle Gary McSorley performed cardiopulmonary resuscitation under instruction from the ambulance control room, Lincolnshire Live reports.
The inquest at Lincoln Coroners' Court heard that the tot's dad Phillip had given her a feed at 5.30am on May 16, 2018, before she was put in her cot on her back and went to sleep.
Mr Enos then woke up at 8.30am and went to work.
He said the baby was sleeping in her cot in the couple's bedroom.
At about 10am however her mum saw Kasey-Leigh was laying on her front.
Mrs Enos, who has recently had twins, said in evidence read to the inquest: "I immediately knew something was wrong.
"I turned her over. Her eyes were closed and there was blood in her nostrils. I screamed for Gary."
Mr McSorley, said in his statement: "She was saying Kasey-Leigh was not breathing."
The tot was aged three months and 11 days when she died, the court heard.
The medical cause of death, also known as cot death.
Lincolnshire Police confirmed there were no suspicious circumstances or third party involvement.
Senior Coroner for Lincolnshire Timothy Brennand said: "Kasey-Leigh died as a consequence of an unascertained process that on balance was a natural process, the causes of which are unascertained.
"On the balance of probabilities this was a naturally occurring phenomenon."
He told Mr and Mrs Enos: "It is clear to me that in you two Kasey-Leigh could not have had better or finer parents.
"You are skilled and experienced, having raised three other children. There's absolutely nothing you could have or should have done to avoid this death."
Kasey-Leigh's death came after Mrs Enos's brother Killian, 19, died in a road crash in Northern Ireland in December 2016.
Carmel Doherty, the baby's grandmother, who had lost her soon recently, said Kasey-Leigh had brought immense happiness to the family, the Belfast Telegraph reports.
"There was such great excitement when she was born because she brought us new hope after what happened to Killian," she said.
"It's so sad now seeing my own child going through what I experienced.
"There's nothing any of us can do or say to fix the broken heart of a mother who loses a child."
