A nanny is someone whose job is taking care of other people's children in their home. While a babysitter might watch kids for an evening, a nanny works regular hours, sometimes full-time, and becomes a steady, trusted part of a child's daily life.

Nannies help with everything from making meals and supervising homework to organizing activities and getting kids to school. Some nannies live with the families they work for, while others come during the day and go home at night. Many nannies care for the same children for years, watching them grow up and becoming almost like family.

The job requires patience, creativity, and genuine affection for children. A good nanny knows how to make nutritious snacks, settle arguments between siblings, teach new skills, and keep kids safe and happy. Some nannies specialize in caring for babies, while others work with older children.

In some countries, especially in Britain, people also use nanny as an affectionate nickname for a grandmother.
