Emma Smith spoke about the tragic cot death of her ten-week-old daughter Maisy after she accidentally fell asleep with her on the sofa.
She said she had known the guidelines on cot death and had gone to sit on the sofa to avoid falling asleep next to her daughter after a night feed.
She told Good Morning Britain: "I put her down bedside me and I didn't mean to but I fell asleep. Then tragically, when I woke up she had died."
A leading child health doctor has welcomed plans to warn parents not to sleep alongside their babies as a way to reduce the 'absolute tragedy' of unexplained infant deaths.
He said that although co-sleeping is safe most of the time, the risks are higher when the adult is very tired, drunk alcohol, used drugs or when they have taken medication which might sedate.
"To address this, we need to help ensure that all families have access to safe sleeping guidance and resources,"he said. "And because we know that vulnerable families are especially at risk of Sids, we need a targeted campaign to promote safe sleeping habits."
A parenting charity has warned that draft guidelines warning new mums not to sleep with their new babies does not 'reflect the reality' of family life and could lead to parents concealing information from health officials.
Belinda Phipps, chief executive of the National Childbirth Trust, raised concerns over draft guidelines aimed at reducing the number of babies who die from sudden infant death.
However, she said that parents should be warned about the risk of sharing a bed with their young children in higher risk situations, including when babies are underweight or premature, or when parents have been smoking or drinking.
New parents should be warned that sleeping together with babies under the age of one increases the risk of sudden infant death, health officials at the National Institute for Health and Care Excellence (Nice) have said.
The health group has produced new draft recommendations calling for all parents to taught about safe sleeping habits in a bid to cut the number of cot deaths.
"Falling asleep with a baby, whether that's in a bed or on a sofa or chair, is risky," said professor Mark Baker, the clinical practice director at Nice.
"This is especially important if parents drink alcohol, take drugs or expose their baby to tobacco smoke."
Experts say placing the baby face down along the thigh offers much more support for while the parent or carer administers blows to the baby's back to tackle choking.
The change in advice, to be officially announced on March 3, comes as a survey of 1,000 parents of under-fives found more a third (38%) have seen their child choke.
Half of these parents admitted they did not know the correct procedure for helping their child, or ways to clear the obstruction.
Leading first aid charities are issuing new advice to parents on what to do if their baby chokes after research showed many have no idea what action to take.
St John Ambulance, the British Red Cross and St Andrew's First Aid have agreed a change to the technique for dealing with babies under one who are choking.
Previously, the advice was to place infants along the parent's arm face down, but this is now changing to placing the baby face down along the thigh.
'4D' images of unborn babies have helped scientists' understanding of their physical and psychological development in the womb.
Researchers took 60 scans of 15 healthy foetuses to create '4D' images - 3D scans that can be seen in real time.
Babies appear to learn about touch while in the womb and can predict, rather than react to, their own hand movements.
New information on the behaviour of babies in the womb may lead to "more understanding" about how children adapt to social situations, regulate stimulation and take a bottle or breast when born.
The study, published in the journal Developmental Psychobiology, found babies in the later stages of pregnancy are capable of touching their lower face and mouth, indicating healthy brain function.
Babies learn about touch while in the womb and can predict, rather than react to, their own hand movements, new research has shown.
Foetuses in the later stages of gestation increased touching between the lower part of their face and mouth, which scientists say is an "indicator" of healthy brain development.
Psychologists from universities in Durham and Lancaster carried out a total of 60 scans of 15 healthy foetuses at monthly intervals between 24 weeks' and 36 weeks' gestation. They used 4D imaging to create scans of life inside the womb.
Worcestershire Acute Hospitals NHS Trust, which is caring for a baby abandoned this morning in Worcestershire, has made an appeal on Twitter for the newborn's mother to come forward:
