Siblings of children with autism are in a unique position. They face challenges (similar to those that parents encounter), but at a time before they've developed appropriate coping strategies. As a result, they need support to ensure that they're informed, feel respected, and know how to be compassionate advocates for their brothers and sisters on the spectrum. The guide is a handbook for teenage (and even pre-teen) siblings that offers guidance on how to productively address feelings and challenges that may arise as an autism sibling. The resource covers a variety of topics; from explaining autism to friends and peers, to coping with a family dynamic that's different from what friends may experience. Two young adult siblings created this resource after connecting with dozens of teens about the ups and downs of growing up with a brother or sister with autism. The advice provided in this guide is based on their questions, concerns, and insight. The tips and stories featured are written by teens who share their experiences.
