A babysitter is a person who takes care of children when their parents are away. They are responsible for ensuring the kids are safe, happy, and entertained. Babysitters often play games, help with homework, and prepare snacks. They can be hired for a few hours or even for a whole day, depending on the parents' needs. Many babysitters are teenagers or young adults looking for part-time work. They may have experience caring for younger siblings or have taken courses in child care. Some families prefer babysitters who have certifications in first aid or CPR, ensuring that the children are in good hands during their time together.
