All bodies go through puberty, regardless of the developmental "age" of a child or the level of their cognitive or academic skills. It can be startling for parents to see their child with an autism spectrum disorder (ASD) begin to develop an adult body and characteristics when they do not have the adult skills, reasoning, or competences to go along with it. Regardless of a child’s cognitive abilities, they will go through puberty and they will need support to understand the changes that are happening to their body, as well as assistance to know that these changes are normal and not something to be scared of. Children with ASD will also benefit from understanding about the social rules that accompany puberty, including those that relate to privacy, hygiene, and relationships with others. While schools teach about puberty and sex education in their health or wellness programs, children with autism often need much more explicit instruction about these topics than what they receive in school. Therefore it often becomes the parents’ responsibility to teach about these topics in a way that will be accurate, meaningful, and appropriate to their child with ASD.
