The role of trauma on the child emotional development is evidenced both in child socialization and performance in school. The purpose of the study was to assess the role of trauma on the children’s emotional development in children’s homes in Laikipia West Sub- County. The study employed ex post facto research design. The study targeted 419 children and 40 administrators living in children’s homes in the Sub-County. Simple random sampling was used to select 88 boys, 87 girls and 10 administrators, making a total sample size of 185 respondents. Questionnaires for the children and interview schedule for home administrators were used for data collection. To establish reliability of the instrument, a pilot study was conducted using 18 children and 4 administrators from two children’s homes. A reliability coefficient of 0.71 was established using Cronbach Alpha Coefficient. Validity of the instrument was ascertained through piloting the questionnaires to increase the face validity, as assistance was sought from the supervisor for content validity. Data was analyzed using descriptive statistics and inferential statistics. The study established that children exposed to distressing phenomena such as death of parent, sex abuse, parents’ abandonment, child labour, caregiver’s mistreatment, separation from parents at early age are at the greatest risk of developing trauma. The study concluded that such children develop anxiety like fear of death, screams and feeling loneliness. Some of them also feel uncomfortable in children`s home and therefore tried to run away. These traumatic situations negatively influenced children hence developing unhealthy emotional development. The study recommends that the Ministry of Health as well as the Children’s Department in the Ministry of Gender Sports and Culture should organize campaigns for creating awareness among public on nature of trauma and the consequences this may have on children emotional development.
