Save the Children urges action for poorest UK children
The charity Save the Children, best known for helping some of the world's poorest families, has launched an appeal to help UK children.
The charity says the UK's poorest children are bearing the brunt of the recession, with some missing out on regular hot meals or new shoes.
The campaign urges the government to focus on benefits for low-paid families and ask employers to pay a living wage.
The government said it was committed to eradicating child poverty.
Researchers for Save the Children surveyed more than 1,500 children aged eight to 16 and more than 5,000 parents, focusing on the lowest income groups.
The study draws on Institute of Fiscal Studies (IFS) figures which estimate that there are 3.5 million children living in poverty in the UK and predict a steep rise in the numbers in coming years.
The charity defines living in poverty as having a family income of less than £17,000 a year.
More than half the parents in poverty surveyed (61%) said they had cut back on what they ate and more than a quarter (26%) had skipped meals in the past year.
Just under a fifth (19%) said their children sometimes had to go without new shoes when they needed them.
Some 19% of children in poverty said they had missed out on school trips and 14% said they did not have a warm coat to wear in the winter.
The report, It Shouldn't Happen Here, also reveals the extent to which children are aware of how much financial strain their parents are under with more than half (58%) saying they thought it was getting harder for their parents to pay for everything.
Some 52% of the poorest children agreed that not having enough money made their parents unhappy or stressed and 43% 'strongly agreed' that their parents were cutting back on things for themselves such as clothes or food.
Parents on the lowest incomes agreed they were more likely to snap at their children (23%) because of money worries compared with better off parents (10%).
The report quotes last month's Department for Work and Pensions figures which showed 61% of children in poverty had working parents. It urges the government to encourage more employers to pay above the minimum wage so that workers can provide for their families.
It says the new Universal Credit system should let working parents keep more of their earnings before benefits are withdrawn and urges the government to pay 80% of childcare costs for the poorest families.
Justin Forsyth, Save the Children's chief executive, said: "Poverty is tearing families apart, with parents buckling under the pressure of mounting bills and children seeing their parents argue more about money.
"We need to help poor families survive the recession."
He added: "Given that most children living in poverty have at least one parent in work; it is appalling that those parents can't earn enough to give themselves and their kids a decent life.
"The government must make work pay by encouraging more employers to introduce a living wage, provide extra child care support to help parents trying to get into work and protect the poorest and most disadvantaged from further cuts."
A Department for Work and Pensions spokesman said: "Despite £150bn being poured into benefits and tax credits over the last decade, the previous government's approach to tackling child poverty has failed, with the UK missing its own 2010 child poverty targets.
"The government remains committed to eradicating child poverty, but we want to take a new approach by tackling the root causes including worklessness, educational failure and family breakdown.
"And our welfare reforms will improve the lives of some of the poorest families in our communities, with the Universal Credit simplifying the complex myriad of benefits and lifting 350,000 children and 550,000 adults out of poverty."
Commenting on the campaign during Prime Minister's Questions, David Cameron said: "We are making sure we target help on the poorest families in our country, which is what we have done through the tax credit system.
"At the same time, I think we should praise all voluntary and big society efforts to help the poorest families in our country as well."
Save the Children aims to raise £500,000 from the charity appeal to help boost low income children's school careers and provide basic essentials such as cookers, furniture or toys for their families.
