In a disturbing new report, one terrified mother said her sons lit fires in the house and that she was choked by her nine year-old and had to go to hospital (see interview below).
The survey, by YouGov on behalf of national families charity 4Children, reveals that more than half of families with children under 18 years old – around 4 million nationwide experience major arguments, conflict and even violence.
• Disagreements over child discipline, 17
• Redundancy/ long term unemployment of one or both parents, 7) and shouting (57).
Most worrying is that 10) of local authorities do not have a domestic violence strategy which mentions violence committed by family members.
And one in 10 (11 of those identified as the most troubled families in some authorities are living with domestic violence and in some areas three quarters of children on child protection orders are on the registers because of concerns over domestic violence in the family.
"Unless urgent action is taken, it is clear that this cycle of violence will continue to plague families for generations to come."
Like many problems that can lead to family breakdown, family conflict and violence can often remain hidden within families for years because of a reluctance to openly admit to the problem and seek help.'
CASE STUDY: 'My sons beat me up and lit fires in the house'
Sandra, 42, has been living with her violent sons for over 14 years in the North of England.
As far as she can remember they have always been violent.
At the age of four, William was already hitting and kicking teachers.
Sandra felt her boys were out of control so she turned to social services for help.
Their response was to send Sandra to a parenting programme which, while it helped, was not well equipped to deal with the scale of Sandra's challenges.
Both her sons were subsequently diagnosed with ADHD (at the ages of six and 11).
By the time William was nine, Sandra's parents had to call the police because he was choking his mother and they were afraid he would harm her further.
Sandra had to attend A&E for her injuries. Once again, Sandra sought help from social services and this time she was sent to a Strengthening Families programme.
But the problem was too serious. She became absolutely terrified of her children as they entered their teenage years.
"I was totally frustrated that I couldn't change things," she said.
They would trash the house, light fires in the house, punch holes in the walls, steal things... pin me against the door and put a knife to my throat.
"I just couldn't take it any more. I was so scared."
Sandra lost count of the times that she called the police for help when the boys became physically violent.
"But they always returned them home after the incidents. I was absolutely terrified," she said.
As a result of these incidents, Sandra developed major depression. Eventually, she was referred to a specific programme through her social worker in her authority working with teenage perpetrators.
