childminder

This term is predominantly used in British English to describe a professional caregiver who operates out of their own residence. In North American English, the term "nanny" or "babysitter" is more common, though "nanny" typically implies a more formal arrangement or a live-in position, whereas a childminder specifically suggests a home-based business environment.

Because the role involves legal registration and professional certification in many jurisdictions, the word carries a connotation of trust and official responsibility. It differs from a "babysitter," which usually refers to a casual, short-term, or adolescent caregiver.
