In Chapter 4 of Parents and Families of Children with Disabilities, in regards to deepening my knowledge on how families cope with the stress of having a child with a disability, I never put into thought of how the siblings of the child dealt with stress.  My focus before was solely on the parents, but siblings are too a part of the family.  In what ways are they effected?  In what ways do they cope?  Are they as accepting or resilient of their brother/sister with the disability?  In spite of their heterogeneity, including characteristics, needs, interests, and capacity to be involved in supporting family members with special needs, members of a family unit are interrelated in myriad ways.  In this connection, events that affect one member of a family also impact others in the family (Carter & McGoldrich, 1980).  Siblings seemed to be overlooked, when they too are affected.  As a professionals, we must respond to the needs of the siblings of children with disabilities as well.  I've learned that one must provide information to the child about exceptionalities, including the disability that affects their brother/sister, observe and discuss with school personnel the educational program of siblings with a disability, including methods, procedures, curricula, and supports, and communicate with community professionals as well as other siblings of students with disabilities, and individualized opportunities and decision-making roles related to participating in the educational and home-life support of siblings with disabilites (Fiedler, Simpson, & Clark, 2007).
