The main goal of preschool institutions is to look after, educate and care for children from the age of 6 months until they start school. Preschool education is an important part of a child's development, and nurses play a key role in the care of children in these institutions. The nurse is an indispensable member of the team in charge of health education. Her presence provides children with the necessary health support, which ensures a healthy and safe environment and successful growth and development. They take care of ensuring and improving the protection of children's health by implementing health protection measures, hygiene measures and proper nutrition measures. Carrying out health education is very important because it develops positive health habits. The nurse's field of work is determined by the Program for Children's Health Protection, Hygiene and Proper Nutrition of Children in Kindergartens. Conducting health education in preschool institutions is an excellent way for a child to master skills that are important for a healthy life and proper development at an early age. In order for a nurse to progress in her work, she is obliged to follow new medical knowledge and improve her knowledge through lectures organized by the Association of Kindergarten Nurses. Preschool is the first step to a healthy way of life, a place where positive habits are acquired and knowledge and skills essential for a healthy life are acquired.
