A mum and her two kids have to live in their coats after being housed in a "freezing cold and damp" council flat, she claims.
Emma Reynolds, son Lewis, three, and daughter Leah, eight, spend day and night wrapped up in extra layers in the "unfit" property in Kings Norton, Birmingham.
The 25-year-old mum claims she wakes every morning to a "big puddle" on her bedroom floor from the dripping window.
The family have had to throw out toys, as well replace the sofa and other furniture and units, as well as pull up carpet and pull down wallpaper due to mould, reports Birmingham Live.

She claims the conditions have worsened her son's airway disease and exacerbated her bone condition.
Emma said: "I started having problems about a month after I moved in. I first noticed black mould in the bedroom and literally water all on the floor.
"I thought there was a leak or something so I just mopped it up and I left it. Then the next day, it came back again.
"Every morning there's a big puddle in my bedroom. It's coming from the windows, it's dripping down from the windows."
The family moved in eight months ago and in December, Emma had to pay over £400 to top up the electricity, she says.
"We have to wear our coats and dressing gowns because it's that cold in here. We've got storage heaters, but they're not that hot so it's freezing in here."
"When I do have them on it's taking a lot of electric, like I've put £40 on two days ago and I've got £15.
"It's still freezing because of the damp. It's costing a lot...we're constantly topping up on electric."
Birmingham City Council is due to demolish the building in the near future and some flats have already been vacated in preparation.
Emma says she's emailed and called the council but has so far not been moved.
"My son has got airways disease and since we've been here I'm constantly at the doctor's because his chest is getting worse and he's had to go on steroids," she continued.
"I suffer with depression as it is and I'm worried about my children's health over it.
"I have a bone condition and some days, I can't walk properly.
"I have pains in my legs and arms, and the damp is making it worse. I'm getting into bed of a night and I'm in agony."
Birmingham City Council has apologised for the issues and vowed to treat the mould.
In a statement, it said: "We are sorry for the problems this tenant has experienced with mould in their flat.
"The block is due to be demolished in the next couple of years.
"In the meantime, we have organised for a contractor to treat the mould and will work with the tenant to rehouse them in line with our allocation policy."
