A mum has claimed black mould in her council flat has caused her baby to be taken to hospital with breathing difficulties.
Chloe Wilkinson, 22, says her nine-month-old daughter Gracie has had to go to the hospital on more than one occasion with a chesty cough after mould was found in the flat including the baby's mattress.
The young mum fears the two things are linked although there is no evidence to say are at this stage.
A spokesman for Swansea Council told WalesOnline measures had been taken to try to solve the mould issue and said air vents and a fitted extractor fan at the property were not being used.
Chloe also claims she was already having to fork out £40 a week on gas bills alone just to keep her flat warm said and ventilating it let all the heat out and cost her more money.
She says she first complained about the mould on June 20 and alleged the council sent someone out who she claimed told her to wipe the wall and paint over it.
But when Chloe went to change her daughter Gracie's cot mattress she claimed she noticed a black mould stain.
Chloe also claimed mould covered the lower wall and window in her bedroom where Gracie also sleeps and the ceiling and window of the bathroom.
Since July, Chloe said the problem had worsened and she said she recently complained again to the council.
The council said in contrast the issue had only recently been highlighted by the tenant on November 7 and it had since made several attempts to contact the tenant to address the issue.
Chloe said that in late August she was worried about her baby's daughter's chesty cough and took her to A&E.
Gracie was diagnosed with a viral infection which went away on its own.
On November 13, Chloe took Gracie to the out-of-hours clinic at Morriston Hospital once again for a chesty cough which had been bothering her for a week.
Gracie was diagnosed with bronchiolitis and she is still suffering from the cough.
Chloe claims she was told to keep windows open to ventilate the rooms but said her gas bill was rising as she tried to keep her flat warm.
She said: "The room is constantly cold. I saw last week that a two-year-old died of black mould. I wasn't that bothered about it until I saw that."
Chloe's fears come after an inquest found that Awaab Ishak died following exposure to untreated mould in his home.
Coroner Joanne Kearsley gave a narrative conclusion for Awaab's death with a medical cause of acute airway oedema with severe granulomatous tracheobronchitis due to environmental mould exposure.
A spokesman for Swansea Council said: "During our visit assessments were made on the property, observing that air vents and a fitted extractor fan were not being utilised by the tenant. This means they have no way of effectively dealing with build-ups in condensation.
"We are continuing to support the tenant with further work to deal with mould present in the property and provided advice on how to deal with condensation.
"Further discussions were had in terms of fitting additional ventilation equipment to help resolve the issue."
