**Short answer:** There's no perfect age, but many autistic adults say earlier is better. A study of autistic university students found that learning they were autistic earlier was linked to better quality of life and well-being. Start simply and positively, with words that fit your child's age, and keep talking over time rather than having one big conversation.

**Key takeaways**
- Many autistic adults say **earlier is better**.
- Learning earlier was linked to **better well-being** in one study.
- Keep it **simple, honest and positive**.
- Make it an **ongoing conversation**, not one big talk.

## When should I tell my child they're autistic?

There's no single right age, but research and autistic adults point toward sooner rather than later. In a study of autistic university students, those who learned they were autistic at a younger age reported **higher quality of life and well-being** as adults.[1]

Many autistic adults who found out late say they spent years thinking something was wrong with them. Knowing earlier can give a child words for their experience and a reason to ask for help.

## What words can I use?

Match your words to your child's age and understanding:

| Age | You might say |
| --- | --- |
| 4 to 6 | "Your brain works in its own special way. It's called autism. It's why loud sounds bother you and why you're so good at puzzles." |
| 7 to 9 | "Autism means your brain notices and thinks about things differently. Lots of people are autistic. It comes with strengths and some things that are harder." |
| 10 to 12 | "You're autistic. It's a different way of thinking and sensing the world, not something wrong with you. Want to learn about it together?" |

Autism is a lifelong difference in how the brain develops, affecting communication, senses and routines.[3] You can share as much of that as your child is ready for.

**Start with strengths.** Link autism to things your child already knows about themselves: a great memory, a deep interest, noticing details, or
  needing quiet.

## How do I keep the conversation going?

**Try:**
- Short talks, repeated over time
- Books, shows or videos with autistic characters or creators
- Answering questions honestly, even "I don't know"
- Letting your child decide who else to tell

**Skip:**
- Treating it like bad news
- One big serious talk and never mentioning it again
- Talking about your child's autism in front of them without including them

**Learning from autistic people.** Autistic-led organizations share resources written by autistic people, which many kids and teens find helpful.

## What if my child reacts strongly?

All reactions are normal. Some kids are relieved, some shrug, and some feel sad or angry. Stay calm, listen, and let them know nothing about how you feel about them has changed.

**Talk to your child's doctor or therapist if....** your child seems very upset for a long time, talks about hating themselves, or seems anxious or low. They can help
  support your child.

## Common questions

### Is my child too young to understand?

Even young children can understand simple ideas, like "your brain works in its own way." You can add more detail as they grow.

### What if my child is upset?

Some kids feel relieved, some don't care, and some feel sad or confused at first. Listen, stay calm, and come back to it later. It's a conversation, not a single moment.

### Should I tell other people first?

Many families tell their child before, or at the same time as, others, so the child hears it from you first, in a positive way.
