How to explain puberty to your nonverbal autistic son

Why puberty hits differently for autistic children

Autistic children often struggle with unexpected changes, and puberty brings a flood of them all at once. Their bodies are changing in ways they can see, feel, and smell - but nobody warned them it was coming.

The sensory changes are often the hardest part. New body hair feels different against clothing. Deodorant has a smell and texture that might feel overwhelming. Voice changes can be jarring for children who are already sensitive to sounds.

Research on interoception - the ability to sense what's happening inside your body - shows that many autistic people have difficulty interpreting these internal signals. Your son might feel the hormonal changes as general discomfort but not understand what's causing it.

For nonverbal children using AAC devices, there's an additional challenge: they need the right vocabulary programmed into their devices to express what they're experiencing. Without words like "growing," "private," or "normal," they can't even ask questions about what's happening.

What works in the moment

1. Use his AAC device immediately. Programme basic puberty words: "body," "growing," "hair," "normal," "change." When he points to new body hair, you can model: "Yes, hair growing. Body changing. Normal." This gives him language for his experience.
2. Show, don't just tell. Use simple drawings or photos of male puberty stages. Visual learners need to see what "growing" and "changing" actually look like. Keep it clinical and matter-of-fact.
3. Address the sensory issues first. If new body hair feels scratchy, let him choose softer fabrics. If deodorant feels weird, try different textures together. Comfort his senses before explaining the concepts.
4. Make a "normal" list. Write down or programme into his AAC: "Hair growing - normal," "Voice changing - normal," "Body getting taller - normal." Autistic children find comfort in knowing what's expected.
5. Use his special interests. If he loves trains, explain that his body is like a train moving from the "child station" to the "teenager station." It stops at different stations (growth spurts, voice changes) along the way.
6. Create a daily check-in routine. Each morning, look in the mirror together. Use his AAC to name any changes: "Hair on face," "Getting taller," "Voice different." Routine reduces anxiety about unpredictable changes.
7. Programme privacy vocabulary. Add "private parts," "private time," "bathroom private" to his AAC device now. He needs these words before he needs to use them.
8. Involve him in hygiene choices. Let him smell different deodorants and choose one. Pick out razors together (even if he won't use them yet). Giving him control reduces overwhelm.

Teach it ahead of time

Social stories work brilliantly for puberty because they break down complex changes into predictable steps. Autistic children cope better when they know what to expect, and puberty stories can be read months before changes begin.

Create a simple social story called "My Body is Growing Up" with photos of your son at different ages, ending with a drawing of teenage features. Include pages like "When I am 12, hair might grow on my face. This is normal. Dad has hair on his face too." Read it weekly, adding new pages as changes happen. This makes puberty feel planned and safe, not chaotic and scary.

What NOT to do

• Don't wait until changes start. By then, his anxiety levels are already high and he's processing too much sensory information to learn new concepts easily.
• Don't use euphemisms or baby words. "Private parts" is clearer than "down there." Autistic children process literal language better than vague terms.
• Don't overwhelm with too much information at once. One concept per week works better than a comprehensive "puberty talk" that might cause shutdown.
• Don't assume he understands emotional changes. Focus on physical changes first - they're concrete and visible. Emotional complexity can come later.
• Don't forget to update his AAC device regularly. As his needs change, his vocabulary needs to expand. Check monthly that he has words for new experiences.

You're doing better than you think

Puberty is confusing for every child, autistic or not. Your son is lucky to have a parent who cares enough to research how to help him understand his changing body. He's doing his best to make sense of new sensations and experiences. You're doing your best to guide him through it. Some days will be harder than others, but you're building his understanding one word, one explanation, one patient moment at a time.
