Binuclear families are alternative family structures that have become more common in recent years. These families are made up of two separate households, each headed by a parent who has ended their relationship with their previous partner. Other synonyms for binuclear families include blended families, stepfamilies, and reconstituted families. These families can be formed by remarriage or the formation of a new relationship, and can involve children from one or both partners' previous relationships. The increased prevalence of binuclear families has led to a shift in societal attitudes towards more inclusive and diverse family structures, which has resulted in greater recognition and support for these families.
