Fire swept through the bedroom of a Tamworth house occupied by a family of eight children.
Firefighters from Tamworth were joined by crews from Warwickshire to tackle the blaze in a property off Woodhouse Lane, Amington on Friday.
"Staffordshire Fire and Rescue Service would urge people to make sure that items like cigarette lighters and matches are kept well out of the reach of children."

A call was received from the address at 1.02pm stating the bedroom was on fire. Investigations at the scene found the cause to be accidental ignition of a mattress.
One appliance from Tamworth attended with two firefighters wearing breathing apparatus tackling the blaze using one hose reel jet.
Watch Manager, Mark Chaplin, said: "It appears the fire started after a three-year-old boy had been playing with a cigarette lighter and accidentally set fire to a mattress.
"The family were downstairs in the living room at the time the fire took hold. A member of the family smelt the smoke and went upstairs to the bedroom and saw the fire. The family immediately left the house and called the emergency services."
Mark added: "One appliance from Warwickshire attended the incident to support Tamworth, providing additional firefighters equipped with breathing apparatus.”
After extinguishing the blaze crews ventilated the building after smoke logging had spread to other parts of the house.
"There was a smoke alarm but it didn't operate because it didn’t have batteries in, so we fitted smoke detectors in the property," added Mark.
"Staffordshire Fire and Rescue Service would urge people to make sure that items like cigarette lighters and matches are kept well out of the reach of children.
"Such items should be locked away somewhere only responsible adults can get to.
"And we would ask everyone to make sure they have working smoke alarms fitted in their home."
Assistant Area commander Brian Griffiths said: "Any parents or carers who have concerns regarding their children playing with fire should contact their local fire station who can offer specialist assistance and advice.
"There is a general misconception that it's only fire that kills but this is not true. Smoke can be just as deadly.
"People can contact Staffordshire Fire and Rescue Service and book a FREE Home Fire Check where we will come to your home and fit a smoke alarm for nothing.
"Just one simple phone call can help protect and save lives."
