Allow the siblings and peers to tell their siblings how they feel. Encourage positive comments and gestures. This is an effective way of shaping behaviors of the child with emotional or behavior issues that may not be socially expectable. Listen carefully and if necessary explain that parents don't always have all the answers. Don't assume that siblings are upset because of the child with emotional or behavior issues.
Siblings have lives that are beyond their sibling with emotional or behavior issues.
Some children are more comfortable than others in expressing theirs thoughts and feelings. Allow siblings to be themselves without the adult expectations. They may be confused about their place in the family. Pay close attention to how often you ask siblings to help, as well as what you ask them to help with. Use babysitters, rather than always depending on the sibling.
