Family structures: ‘In a nuclear family, a mother and father live together with their children but separately from other family members. They may be married or “co-habiting”.’ ‘In a same-sex family, a same-sex couple takes care of children. They may be gay or lesbian.’ ‘In a reconstituted family, children live with one natural parent and a step-parent. Families may also include step-sisters and brothers, and/or half-sisters and brothers.’ ‘In an adoptive family, children may live with adopted or foster parents.’ ‘In a communal family, children may live with their parents in communes where other members are also involved in the childcare.’ ‘In a nomadic family, parents do not have a permanent home, and travel from place to place with their children – traveller families, for example.’ ‘In a lone-parent family, a single parent takes care of children, either through choice or for other reasons. This may be, for instance, because of divorce or separation, or the death of a partner.’ ‘In an extended family, family members live together and share the care of children.’
