The following quote can be found at para 2.26 of "Ending child poverty: everybody's business"

"Balancing work and family life is difficult. Caring responsibilities (for example caring for a disabled, elderly or sick family member), large families and relationship breakdown can make it more difficult. Parents of disabled children face particular constraints, often due to problems finding childcare to meet their child’s particular needs. Research suggests that around six in ten mothers with disabled children are in work, compared with around seven in ten mothers with non-disabled children. A higher proportion of children in families with a disabled child are in lone parent families, which increases their risk of poverty and worklessness. Families that receive the Disability Living Allowance have a relatively low risk of relative income poverty (although families with disabled children still have higher costs which may affect living standards), and ensuring that all families receive the support to which they are entitled could play an important part in securing a route out of poverty."
