The discussion about children's rights and their protection is always a current topic of all institutions, organizations and society in general. Although there is a strong legal framework that protects children's rights, where the Convention on the Rights of the Child stands out the most, today we live in a world where children's rights are threatened more than ever before, and children are faced with numerous challenges. Modern digital environment, gender identity, climate change, war events and migrant children put the whole society against the wall in the realization and protection of children's rights. Places that should be the safest for the growth and development of children, such as families and educational institutions, become places of violence against children and discrimination. One of the most important roles in the protection and promotion of children's rights is played by the Children's Ombudsman as an independent body that was introduced in the Republic of Croatia in 2003. From then until today, the ombudsman for children continuously works to protect children's rights, cooperates in the adoption of laws and regulations for the welfare of children, and warns of existing problems and needs. The paper analyzes the situation in 2023 regarding the work of the Ombudsperson for Children in the Republic of Croatia, which will show challenges in various areas of protection of children's rights, including personal, educational, health, social and economic rights, and the protection of children in the justice system. The paper will show that there is an increase in the number of reports of violations of children's rights from year to year, while 2023 is the year in which the reports are the most numerous.
