Which term defines an individual who provides personalized care for children while their parents are at work?

The correct term for an individual who provides personalized care for children while their parents are at work is "nanny." A nanny typically works in a family's home and is responsible for the child's daily needs, including supervision, educational activities, and various aspects of childcare. Nannies often develop long-term relationships with families and provide individualized attention to the children in their care.

While a childminder also provides childcare, they usually operate from their own homes and may look after children from multiple families simultaneously. An au pair, on the other hand, is often a young person from another country who lives with a host family to provide childcare and may also assist with light household duties in exchange for room and board. A paraprofessional usually refers to someone who assists a professional in an educational or related setting, which doesn't fit the context of personalized childcare. Thus, a nanny is the most suitable term for the described role.
