My child can't sound out words — is something wrong?
You point at the word. You say it slowly: "cuh — ah — tuh." You wait.
Your child says "dog." Or "I don't know." Or just looks at you with the specific blank expression that makes you wonder, for a brief and unwelcome moment, whether something is wrong.
Take a breath. This is one of the most common stuck points in early reading, and in nearly every case it's not dyslexia, not a developmental issue, and not a sign that you've done anything wrong. It's almost always one of four very specific missing skills — each with a name, and each with a fix.
Here's how to figure out which one you're looking at.
First, lower the stakes
Before we diagnose anything: if your child is four, this is normal. If your child is five and only just starting, this is also normal. The skills below typically come online between ages five and seven, with a wide spread of what's "on time."
What you're trying to do isn't speed up the timeline. It's spot which specific skill is missing so you can practice the right thing — instead of practicing the wrong thing harder, which is how reading turns into a battle.
The four common causes
1. They don't actually know the sounds yet
The most common cause, and the easiest to miss, is that your child knows the letters but not the sounds. They can tell you "that's an S," but they can't tell you that S says /sss/.
How to check: Show them a single letter — no word, just the letter — and ask "what sound does this make?" Do it with five or six letters. If they hesitate, name the letter instead of producing the sound, or guess different sounds on different days, the sounds aren't solid yet.
What to do: Stop trying to read whole words for a bit. Go back to building rock-solid sound knowledge with one small group at a time. (The first seven sounds to focus on are s, a, t, p, i, n, m — they unlock more readable words than any other starting set.) Five minutes a day, sound-first, until they can produce the sound the moment they see the letter.
2. They're saying letter names instead of sounds
This one trips up a lot of kids who learned the alphabet song before they learned phonics. They look at cat and say "cee — ay — tee." Those names don't blend into anything. Cee-ay-tee is just three syllables that happen to share a page with the word cat.
How to check: Listen carefully when they sound out a word. Are they saying /k/ /a/ /t/ or "cee-ay-tee"?
What to do: Gently model the difference. "The letter is called 'see,' but it makes the sound /k/. Listen — /k/, /a/, /t/, cat." Be patient with the schwa — pure consonant sounds are physically hard to produce, and "tuh" instead of crisp "/t/" is fine at this stage. Better a slightly fuzzy phoneme than a letter name.
3. They can say the sounds but can't blend them
This is the one parents most often misread as "they're just not getting it." Your child says /k/ /a/ /t/ clearly and correctly — and then says "I don't know what word that is."
That's not a reading failure. That's a missing skill called oral blending, and it's separate from knowing the sounds.
How to check: Try it without letters at all. Say the sounds out loud — "m — a — p" — and ask what word that is. If they can't do it without letters, they won't be able to do it with letters either.
What to do: Practice blending orally before adding letters back in. In the car, at bath time, while making dinner: "I'm thinking of a word. It's /s/ /u/ /n/. What is it?" Start with two-sound words (at, in, up), then three-sound words. The letters can wait until oral blending feels easy.
4. They can blend but not segment
The reverse problem. Your child reads cat on the page just fine — but if you ask "what sounds are in the word map?" they look at you like you've asked them to do calculus.
This matters less for reading and more for spelling, but it's worth practicing alongside blending because the two skills reinforce each other.
What to do: Play the same kind of game as oral blending, but in reverse. "What sounds are in 'sun'?" Tap a finger for each sound. Robot talk works well — say a word in robot voice, broken into sounds, and have them say it back normally. Then swap.
When to actually be concerned
Most reading struggles at four, five, and even six are about the four issues above. The threshold for asking the school for a closer look is usually:
- Your child is past their seventh birthday and consistent daily practice over several months hasn't moved the needle.
- They struggle to remember sounds day-to-day, even ones you've practiced many times.
- They have real difficulty with rhyming or hearing the first sound in a word.
- There's a family history of dyslexia or reading difficulty.
Any one of those is reason enough to ask for a phonological screening — not because something is definitely wrong, but because early support is far easier than late support. Most schools will do this if you ask.
What to do tonight
Pick one of the four issues above that fits your child best. Try the diagnostic. Then play the matching game for five minutes — no more.
The thing that helps most isn't intensity. It's repetition without pressure: a little bit, most days, in a context where being wrong doesn't feel bad. That's basically the whole design brief for Picture This! — daily phonics practice that doesn't turn into a battle. Built around sound-first teaching, with the four skills above woven in so kids practice them without realizing.
You're not behind. Your child isn't broken. There's almost certainly a specific small thing missing — and now you know how to find it.
