Zion’s first word was banana.

Not mama. Not dada – though those were in the mix for a while, along with hi, bye and a few others. But banana was the one he chose. He said it the way toddlers say words they’re proud of, like the word itself was the prize.

By 14 months, all of it was gone.

Not fading… Gone. And we would not hear our son’s voice again for thirteen more months.

We were told he had a speech delay.

But he had been speaking. On time. And then he wasn’t. So what was it? A delay? A regression? Something else that nobody had a name for yet? At the time, Zion carried a diagnosis of severe speech delay, and he still carried it after he started talking again. But what does that label actually mean for a child who started on schedule and then stopped?

That question sent me looking for answers at 2 a.m. more times than I’d like to admit. If it’s what sent you here, this is the article I wish had existed.

The short answer

A speech delay can be a sign of autism, but most children with speech delays are not autistic.

The more important question isn’t simply whether your child is talking. It’s why they aren’t talking.

A child with a speech delay is having difficulty communicating at the expected pace for their age. An autistic child may also have a speech delay, but they’re usually showing differences in other areas too, like social interaction, play, sensory processing, or the way they use communication itself.

Here’s the distinction that finally made it click for me:

🗯️ A speech delay is a difference in the pace of communication.
🗯️ Autism is a difference in the architecture of communication.

A child with a speech delay is usually trying to communicate but doesn’t yet have the words or language skills to do it. A child with autism may be developing communication along a different path altogether, including how they connect with other people, share experiences, and use language.

Of course, these aren’t two separate boxes.

Many autistic children have a speech delay.

Many children with speech delays are not autistic.

And many families, ours included, spend months living in the uncomfortable space between those possibilities while they wait for answers.

Is a Speech Delay a Sign of Autism?

Sometimes. But speech delay by itself is rarely enough to point toward autism.

When clinicians evaluate a young child, they’re looking at much more than the number of words they can say. They’re watching how your child shares attention, responds to other people, plays, imitates, gestures, and reacts to the world around them. They’re also asking an important question that many parents don’t realize matters until they’re sitting in the assessment room: was your child always delayed, or did they lose words they had already learned?

That distinction changed everything for our family, and it’s one of the biggest reasons I wanted to write this article.

What is a speech delay? (And how it differs from a language delay)

The phrase speech delay gets used all the time, but it’s actually a bit of a catch-all. Most parents use it to mean, “My child isn’t talking as much as other kids their age.” Clinicians, however, are usually trying to figure out what part of communication is delayed.

Common examples include:

• Expressive language delay: your child understands much of what you say but struggles to put their own thoughts into words and sentences.
• Receptive language delay: your child has difficulty understanding spoken language, following directions, learning new vocabulary, or making sense of what they hear.
• Speech sound disorders: your child knows exactly what they want to say but has difficulty producing certain sounds clearly. In some children, this is an articulation disorder. In others, it may be a motor planning disorder such as childhood apraxia of speech.

You may also hear the term late talker. This usually refers to a toddler between 18 and 30 months who has a smaller spoken vocabulary than expected but otherwise shows typical understanding, play, and social interaction. Some late talkers catch up on their own, while others go on to be diagnosed with a language disorder or another developmental difference. Unfortunately, there’s no reliable way to know which child you have in the beginning, which is why “wait and see” can be such frustrating advice for parents.

A child can have one of these challenges, or several at the same time.

Here’s the part that took me the longest to understand: these labels describe what is happening, but they don’t necessarily explain why it’s happening.

A diagnosis of expressive language delay tells you that your child’s language skills aren’t developing as expected for their age. It doesn’t tell you whether the underlying reason is autism, childhood apraxia of speech, hearing loss, developmental language disorder, or something else entirely.

That’s why a diagnosis of speech delay is often the beginning of the conversation rather than the end of it. It’s a description of what professionals can see today while they’re still trying to understand the bigger picture.

Speech Delay vs. Autism: How to Tell the Difference

The question most parents are really asking isn’t whether their child is talking. It’s whether speech is the only thing that’s different.

If the only area of concern is communication, you may be looking at a speech or language delay. If your child is also showing differences in social interaction, play, sensory processing, or repetitive behaviours, autism becomes more likely.

That’s because autism isn’t defined by speech alone. Clinicians look at a child’s overall pattern of development, and communication is just one piece of that picture.

Joint attention: one of the earliest clues

A toddler with a speech or language delay often still communicates in many other ways. They may not have many words yet, but they’re usually eager to share experiences with the people around them.

You might notice them:

• Bringing you a toy just to show you something they find interesting.
• Pointing at an airplane, then looking back to see if you’re watching too.
• Following your gaze when you look across the room.
• Copying simple actions like waving, clapping, or pretending to stir a spoon.
• Pulling you toward something they want while watching your reaction.

This back-and-forth sharing of attention is called joint attention. It usually develops before spoken language, which is why it’s one of the earliest things clinicians look for during an autism evaluation.

A child with autism may have differences in joint attention, but it’s important to remember that no single behaviour can tell you whether a child is autistic. Some autistic children point, make eye contact, and enjoy affection. Others don’t. It’s the overall pattern of development that matters.

Autism can also affect the way language is used once it begins to develop. Some children rely heavily on repeated phrases they’ve heard from parents, books, or television. Others seem to learn language in larger chunks before gradually breaking those chunks apart into their own flexible sentences. This doesn’t necessarily mean they’re “just repeating” words. For many children, it’s a genuine part of how language develops.

Speech delay, on the other hand, is usually a more isolated challenge. The child wants to communicate and connect in age-typical ways but is delayed in developing the speech or language skills to do so.

No two children fit perfectly into a checklist, and that’s why an autism evaluation looks at many different areas of development instead of focusing on speech alone.

Echolalia and Scripting: When Words Aren’t Being Used the Way You Expect

One of the reasons autism can be difficult to recognize is that some autistic children seem to have plenty of language.

They may know hundreds of words, sing every song from their favourite movie, or recite entire books from memory. At first glance, it can seem like their speech is developing normally.

But it’s not just about how many words a child knows. It’s also about how they’re using those words.

You may hear professionals use terms like echolalia or scripting to describe language that is repeated rather than created in the moment. These phrases can come from parents, siblings, books, songs, television, or everyday routines.

You might notice your child:

• Repeating a question instead of answering it.
• Quoting lines from a favourite TV show or movie.
• Using the same phrase in many different situations.
• Singing jingles or reciting books from memory.
• Seeming to have lots of words, but finding back-and-forth conversation difficult.

For example:

• A child falls down, looks at their parent, and says, “Are you okay?” They’re not asking if their parent is hurt. They’re using a familiar phrase because they want their parent to ask them if they’re okay.
• Another child repeats the same line from a favourite cartoon every time they’re excited or frustrated, even though the words don’t seem to fit the situation.

To someone who doesn’t know the child, this can sound like meaningless repetition.

Often, it isn’t.

Many autistic children use familiar phrases to communicate long before they’re able to create flexible, original sentences of their own. Those repeated phrases may be serving a real purpose, even if that purpose isn’t immediately obvious to the people around them.

This is one of the reasons speech can be misleading. A child may have an impressive vocabulary but still struggle to use language to ask questions, share experiences, carry on a conversation, or communicate their own thoughts and needs.

Looking at the number of words a child knows only tells part of the story. Understanding how those words are being used often tells you much more.

What Is Language Regression?

For many families, the concern isn’t that their child never started talking.

It’s that they were talking.

Maybe they had ten words. Maybe fifty. Maybe they were singing songs, naming colours, or calling for Mommy and Daddy. Then, over the course of days, weeks, or months, those words began to disappear.

This is called language regression, and it can be one of the most terrifying and truly heartbreaking experiences a parent goes through.

You start questioning yourself.

Did I imagine it?

Was I expecting too much?

Maybe they’ll start talking again tomorrow.

For many parents, there isn’t one dramatic moment. It’s something they notice gradually.

One day they realize they haven’t heard a favourite word in weeks. A song they used to sing has gone quiet. Instead of adding new words, their vocabulary is getting smaller.

What does language regression look like?

Language regression can look different from one child to another. You might notice your child:

• Stops using words they previously used consistently.
• Speaks much less than they did a few months earlier.
• Stops answering to familiar words or questions.
• Loses interest in songs, nursery rhymes, or games they once enjoyed.
• Begins communicating more through gestures, crying, or pulling an adult by the hand instead of using words.

Some children lose only a few words. Others lose most or all of their spoken language.

Regression doesn’t always happen overnight, although for some children, it does. For many families, it’s gradual enough that they spend months realizing something is wrong or different, but they can’t quite put their finger on what.

Is language regression a sign of autism?

Sometimes, yes.

Not every child who loses language is autistic, but language regression is one of the more recognized early signs of autism, especially when it’s accompanied by the loss of other social or communication skills.

You might notice that your child has stopped:

• Using words they used consistently before.
• Pointing to show you things.
• Waving goodbye.
• Responding to their name.
• Making eye contact as often as they used to.
• Bringing you toys or trying to share experiences with you.
• Playing with other people in the ways they once enjoyed.

For many autistic children, regression happens sometime between 12 and 24 months of age, although it can happen earlier or later. Some children lose only a handful of words. Others lose much more.

That said, autism isn’t the only possible cause. Hearing loss, certain neurological conditions, and other developmental disorders can also lead to a loss of language or other developmental skills.

Any loss of previously acquired language should be taken seriously. If your child has stopped talking, stopped pointing, or seems to be losing skills they once had, don’t wait to see if they grow out of it. Make an appointment with your child’s doctor or pediatrician as soon as possible, and ask for a developmental assessment.

Even if it turns out not to be autism, it’s always better to investigate regression early than to hope it resolves on its own.

Our Experience with Language Regression

Language regression wasn’t something I recognized overnight.

When Zion was around a year old, he had started saying words like “Mama,” “Dada,” “banana,” and “hi.” He loved music, and he’d happily sing along to parts of nursery rhymes in his own toddler way. Nothing about his language made me think we were about to begin a completely different journey.

Then, slowly, those words began to disappear.

But as I began researching and reading about toddler development, I realized that instead of hearing new words every week, I was noticing the opposite. Words I hadn’t even realized he’d learned stopped showing up. Songs became quieter. Conversations that had once been part of our day simply…weren’t anymore.

Like most parents, I started searching for answers. One article told me boys often talk later than girls. Another said to wait until he was two. Others warned that language regression could be an early sign of autism. Every website seemed certain, yet no two of them agreed with each other, and I was left wondering which advice I was supposed to trust.

Looking back now, I can see that the words were only one piece of a much bigger picture. There were other changes happening too. He wasn’t communicating with us in quite the same way, and some of the little social interactions we’d taken for granted had started to fade as well. At the time, though, I couldn’t see the pattern. I just knew that my little boy had once called me “Mama,” and now he didn’t.

What Should You Do If Your Child Loses Language?

If your child has lost words or other communication skills they previously had, don’t ignore it and don’t assume they’ll simply grow out of it. While some children do regain lost skills on their own, regression is something that deserves prompt evaluation.

Here are the first steps I would recommend:

1. Book an appointment with your child’s doctor.

Tell them exactly what has changed, when you first noticed it, and whether you’ve seen any other developmental changes alongside the language loss.

2. Ask for a hearing assessment.

Even if you think your child hears well, hearing should always be checked when there’s a change in speech or language development.

If wait times are long for hearing assessments in your city, you can opt to pay for a hearing assessment at a private clinic.

3. Request a developmental evaluation.

Ask directly for a developmental evaluation. It’s okay to be insistent. If autism is a possibility, it’s important to begin the assessment process as early as possible. Waiting to “see what happens” can delay access to services that may help your child.

4. Contact your local early intervention program.

In many areas, children can begin receiving speech therapy or other developmental supports before they have a formal diagnosis. You don’t have to wait until every answer is in place before asking for help.

5. Write down what you’ve noticed.

It can be surprisingly difficult to remember exactly when changes happened. Keeping notes about words your child has lost, new behaviours you’ve noticed, or videos from different stages of development can be incredibly helpful during appointments.

If preparing for this type of doctor’s visit feels overwhelming, you aren’t alone. That’s why I created the system I wish I’d had when we first started this journey. The Doctor’s Visit Playbook helps you organize your observations, prepare your questions, and walk into every appointment feeling confident and ready to advocate for your child.

While You’re Waiting for Answers

Waiting for assessments, referrals, or therapy appointments can feel endless. You may find yourself questioning every behaviour, comparing your child to other children, or replaying old videos on your phone looking for clues.

If that’s where you are, I want you to know you’re not alone. I’ve been there too.

While you’re waiting, keep supporting your child’s communication in every way you can. Talk to them. Read together. Sing songs. Follow their interests. Celebrate every attempt they make to communicate, whether it’s a word, a gesture, a sound, or a look.

Should You Start Speech Therapy Right Away?

I would. I did, when Zion regressed.

I think speech therapy is especially important if your child shows no other signs of autism.

Even if you’re still waiting for answers, I recommend booking a few speech therapy sessions if you can. If you have insurance, part or all of the cost may be covered, making it an excellent place to start.

Just as importantly, don’t think of speech therapy as something that’s only happening to your child. Sit in on every session if you’re able. In fact, I’d go out of my way to make sure I can be in the room for every session. Watch how the speech-language pathologist interacts with your child, ask questions, and pay attention to the little strategies they use during play.

I learned an incredible amount simply by observing. Many of those same techniques became part of our everyday routines at home while we played, read books, and went about our day.

If your child isn’t ready to communicate yet, that’s okay. You’re still learning the skills you’ll use to support them when they are.

Focus on where you are today. Your child needs your attention, your patience, and your encouragement far more than they need a perfect parent.

Our Experience Getting Language Back

One day, at around 27 months old, Zion began talking again.

Looking back, I don’t believe there was one magic treatment or one breakthrough moment.

We worked with speech-language pathologists and learned how to better support communication at home. We made changes to his diet. We addressed nutritional deficiencies. We focused on sleep, reducing inflammation, and creating an environment where his body seemed calmer and more regulated.

We were working on many things at once, and I believe that addressing Zion’s nervous system, gut health, and inflammation, along with his early intervention program, is what allowed Zion to finally begin communicating again.

At first it was hand leading and eye contact that returned. Then, some basic use of sign language. Suddenly, and truly overnight, Zion began speaking again.

I was in an airport, taking Zion to Ontario to visit my family, and I heard him babbling in a little toddler voice I hadn’t heard in over a year. I stopped in my tracks in the busy airport, to try to hear his sweet voice better, and realized he was gesturing at a large painting we were walking beside. He was naming the colours he saw. Pink. Blue. Yellow. Green. Zion not only knew his colours, but he could say them all.

If I’m 100% transparent, the words came out like bwoo, yewwow, and gween, but I think that made it all the more sweet. As a mama of a non-verbal child, one of my greatest grievances was worrying I might never hear Zion’s baby voice again, and hearing those sounds was an answer to a million prayers.

Over the course of the next week, I discovered Zion knew hundreds of words. All the things he loved to eat. All of his favourite toys. The names of dozens of animals. Mama. Dada. The names of his sister, cousins, aunts, uncles, and grandparents.

He was learning language all along. His body just hadn’t been able to make the words come out.

Looking back, I believe the changes we made to support Zion’s overall health played an important role in helping him find those words again. I know not everyone shares that perspective, but it was an important part of our family’s journey.
