Finding a few clear examples of stopping phonological process can make a world of difference when you're trying to figure out why a toddler is swapping certain sounds. If you've ever heard a three-year-old look at a bright yellow sun and call it a "tun," you've seen this process in action. It's one of those things that sounds adorable at first, but as a parent or caregiver, you eventually start wondering if it's just a phase or something that needs a bit of extra attention.
To put it simply, stopping is what happens when a child takes a "long" sound—the kind you can hold out, like /s/, /f/, or /sh/—and replaces it with a "short" stop sound like /t/, /p/, or /d/. It's basically the mouth's way of taking a shortcut. Long sounds require a lot of breath control and precise tongue placement, while stop sounds are like a quick burst of air that's much easier for a developing brain to coordinate.
Why kids use stopping in the first place
Before we dive into specific examples, it's worth mentioning that this isn't just your kid being "lazy" with their speech. Learning to talk is a massive physical and neurological feat. Think about the sound /s/. To make it, you have to hold your tongue in just the right spot, leave a tiny gap, and blow a steady stream of air through it. If you move your tongue a fraction of an inch, the sound breaks.
A "stop" sound, on the other hand, is exactly what it sounds like. You block the airflow completely and then release it. For a little kid, it's way easier to just shut the gate (stop the air) than it is to try and maintain that perfect, steady "leak" of air. That's why examples of stopping phonological process are so common in early childhood development.
Common examples of stopping phonological process
Let's look at some of the most frequent sound swaps you'll hear. Most of the time, these follow a very predictable pattern where the "stopped" sound is made in roughly the same part of the mouth as the original sound.
The /f/ to /p/ swap
This is one of the earliest forms of stopping you'll likely notice. Since both /f/ and /p/ involve the lips, the child just swaps the "leaking" air of the /f/ for the "burst" of the /p/. * "Fish" becomes "pish" * "Fan" becomes "pan" * "Fork" becomes "pork" (which can get confusing at dinner time!) * "Feet" becomes "peet"
The /s/ to /t/ swap
This is probably the most classic example. Both sounds involve the tongue being near the roof of the mouth right behind the front teeth. * "Sun" becomes "tun" * "Soap" becomes "toap" * "See" becomes "tee" * "Bus" becomes "but" (Wait until they try to say "sit"!)
The /v/ to /b/ swap
Just like /f/ and /p/, these two are "lip" sounds. The only difference is that /v/ and /b/ use the vocal cords (they're "voiced"). * "Vacuum" becomes "bacuum" * "Van" becomes "ban" * "Vest" becomes "best" * "Love" becomes "lub"
The /sh/ to /t/ or /d/ swap
The "sh" sound is a bit more complex, so kids often default to a simple /t/ or /d/ sound to get through the word faster. * "Ship" becomes "tip" * "Shoe" becomes "too" * "Shake" becomes "take" * "Wish" becomes "wit"
When should you expect this to stop?
It's totally normal for a two-year-old to use these examples of stopping phonological process. In fact, it's expected. However, as kids get older, they usually start mastering that breath control we talked about.
Generally speaking, sounds like /f/ and /s/ are usually mastered by age 3 or 4. If a child is still saying "pish" for "fish" by the time they're starting preschool, they might be slightly behind the curve, but it's often still within the realm of normal development.
The sounds that take a bit longer to "un-stop" are things like /sh/, /ch/, /z/, and /v/. It's not uncommon to hear stopping with these sounds until a child is 4 or even 5 years old. If you've got a kindergartener who is still calling their "shoes" their "toes," that's usually the point where a speech therapist might want to take a closer look.
How to help without being "that" parent
We've all been there—you want to help your child, but if you spend all day correcting them, they're going to stop wanting to talk to you. Nobody likes being told "No, say it like this" fifty times an hour. Instead of direct correction, there are a few low-pressure ways to handle examples of stopping phonological process at home.
Try "Recasting"
This is the gold standard for speech development. When your child says a word using stopping, you just say it back to them correctly in a natural sentence. * Child: "Look at the big pish!" * You: "Oh, you're right! That is a big, orange fish. I like that fish." You aren't asking them to repeat it; you're just giving their brain a "clean" version of the sound to listen to.
The "Long vs. Short" Game
Sometimes kids just need to realize that there is a difference between sounds. You can talk about "leaky sounds" (like the snake sound /sssss/) and "pop sounds" (like the popcorn sound /p/ or /t/). * "Can you make a long snake sound? ssssss." * "Now make a popping sound! p-p-p." Making it a game takes the pressure off the actual words and focuses on the physical mechanics of the mouth.
Visual Cues
Sometimes, a little visual help goes a long way. For /f/, you can gently touch your top teeth to your bottom lip to show them where the sound comes from. For /s/, you can put a finger to your lips or draw a "long line" in the air with your finger to represent the long stream of air.
When to reach out for a pro's opinion
While most kids outgrow stopping on their own, it's always okay to ask for help if you're worried. If your child is over the age of 4 and their speech is really hard for people outside the family to understand, it might be time for a quick chat with a speech-language pathologist (SLP).
Another sign to look for is if the stopping is happening with all sounds, even ones they should have mastered. Or, if they seem frustrated because they can't get their point across, a little bit of speech therapy can work wonders. It's usually not about "fixing" the child, but rather giving them the tools to move their tongue and control their breath a little more effectively.
Wrapping it up
At the end of the day, seeing examples of stopping phonological process in your child's speech is usually just a sign that they're busy learning the ropes of a very complicated language. It's a bridge between the babbling of babyhood and the clear communication of big-kid life.
Whether it's "tun" for "sun" or "pish" for "fish," these little quirks are part of the journey. Keep modeling the right sounds, play some silly mouth games, and try to enjoy the cuteness while it lasts—because before you know it, they'll be teenagers, and you'll be wishing they'd go back to calling their "shoes" their "toes."
