Denmark invests a lot in the quality of life, and therefore in the education system, which is of high quality and is often highlighted as an example of the organization of education in general. The Danish curriculum is based on a holistic and integrated approach to early and preschool children. There is a great emphasis on children's participation in the creation of the activities themselves and their involvement in the decision-making process. It emphasizes the equality of all children, encourages the process of socialization and helps parents in the parenting process. Education in Denmark is based on the acronym P.A.R.E.N.T. which includes everything that parents should do during their child's growth, for which children's play is a very important factor in children's development. Play is considered the most important activity in a child's life, because by playing, the child learns in various ways and gets to know the world around him. Children in Denmark spend most of their time in nature because this is how they prepare for the future, get to know their limits and strengthen their immunity. In contrast to the Danish educational system, in Croatia, not so much time is spent outdoors and a structured approach to educational goals is nurtured, but this does not make it of lower quality than the Danish educational system. The aim of this work is to compare the Danish and Croatian curriculum of early and preschool education and to show the importance of children's play in Denmark.
