stepmummy

Stepmummy is the informal, affectionate British and New England term for a stepmother — the version children use when they're young enough to still say 'mummy' rather than 'mum' or 'mom.' It carries a soft, familial warmth that reflects the changing nature of modern blended families.

Stepmummy is the informal, affectionate British and New England term for a stepmother — the version children use when they're young enough to still say 'mummy' rather than 'mum' or 'mom.' It carries a soft, familial warmth that reflects the changing nature of modern blended families. Unlike the fairytale connotations of 'stepmother,' stepmummy is intimate and often used by children and adults alike when speaking fondly of a close parental relationship formed outside biology.

She'd always called her stepmummy by that name, even after she turned thirty.
