Siblings of the autistic child may feel left out or that their parents love them less as a result of all the attention needed to help the autistic child with daily living. There may arise issues with jealousy if the sibling does not understand why the parents attention and assistance is needed so greatly by the autistic child. Another issue of stress for the non-affected child may be with their peers. Though they are not the ones who have autism they may find themselves at the receiving end of ridicule and schoolyard teasing. This will often cause even further resentment of the autistic child.
Though sibling rivalry is a normal part of growing up, a parent with a special needs child needs to take special care with the siblings to ensure resentment and possibly hatred do not arise. Autism affects everyone in the family, and every child or parent associated with autism needs to be taught and helped to adjust to having an autistic loved one.
