Jane suffers from depression due to Simon's death and has difficulty with most of her daily activities. Death as a stressor affected the entire family. The impact of death on the family system creates a structural void that requires homeostatic adjustments. Jane's depression is classified as a mental illness (Falkov, Mayes, and Diggins 1996). This does not necessarily have a negative impact on the care and developmental needs of your children. However, where a parent suffers from persistent and/or severe mental health problems, children in the household are more likely to be at risk or suffer significant harm. A child at risk of significant harm or whose well-being is compromised may be a child who has inadequate caring responsibilities. An ecological theory first proposed by Bronfenbrenner (1979), it provides a framework for understanding the dynamic ways in which children's contexts influence their development and gives us insight to support the provision of nurturing and responsive care. Bronfenbrenner (1979), as cited in the works carried out by Skinner (2012, p2), states that "the ecological environment is conceived as a set of structures nested each inside the other like a set of Russian dolls" (Bronfenbrenner, 1979) . This ecological systems theory was developed by Bronfenbrenner (1979) in hopes of explaining how “everything about a child and the child's environment influences how a child grows and develops” (Bronfenbrenner 1979 cited in Skinner (2012, p4) and the deterioration of the relationship with his children are now starting to manifest themselves in the behavior of Thomas and Olivia. Within this structure there are five layers arranged from the closest individual to the furthest one: the microsystem, the mesosystem. , the exosystem, the macrosystem and the chronosystem, on which these systems have an ongoing impact. development of an individual (Bronfenbrenner, 1994 cited in Skinner 2012, p3). of development is recognized as a unique individual with their own biological and maturational characteristics (such as temperament and developmental level) which are influenced to a large extent by their genetic heritage (Elder, 1998). The well-being of Jane and her children is the focus of this therapy. The most important influences on children's development are the immediate events, interactions and relationships with which they have direct contact. However Bronfenbrenner (1994) cited in the works carried out by (Skinner 2012, p3) suggests that "the focus on development, particularly in children, makes the application of ecological systems theory to adults somewhat more difficult than it might otherwise happen" Kulik, & Rayyan,
