In the master’s thesis, I present a process of parents’ grieving in the case of a loss of the child during pregnancy or soon after birth. In the thesis, I included the topic which is connected to the beginning of the child loss until the period when the parents already exited the process of grieving when losing a child. For the process of grieving, it is important for the parents to find the way of expressing sorrow and disappointment in losing a child, to have the environment which recognizes, understands, and offers help and support to parents, and to have information where parents can find psychosocial help and support if they want and need it. The research in the master’s thesis is based on personal experiences of individuals, parents, therefore fathers and mothers, who have the experience of the child loss during pregnancy or until the 28th day after the childbirth and there were no more than five years from their experience of losing a child. We were interested when and how the process of grieving began and how the process of grieving was happening, how the parents experienced the loss on the emotional and physical level, what was their greatest stressor in the process of grieving, what was that which represented a protective factor for them and what was their risk factor, how they experienced cooperation with formal and informal networks of help in the process of grieving, and how the experience of the child loss influenced their grieving today. The results of the research showed that in spite of the fact that the child loss represents the hardest experience in their lives for the parents and the beginning of grieving the hardest time in their lives, the parents can integrate the experience of the child loss in their daily routine and live a different, sometimes even more qualitative life in relationship towards themselves and others.
