How Many Words Should an 18-Month-Old Say?

At 18 months, speech development can vary, but most parents still want some kind of benchmark. The bigger question is not just the exact word count, but whether your toddler is showing steady progress in sounds, words, understanding, and communication.

This guide explains what language milestones are common around 18 months, what variation can still be normal, and when it makes sense to ask more questions.

Your Toddler Just Turned 18 Months—And You’re Counting Words

Here’s what you need to know right now: The range of normal for 18-month-old speech is HUGE. And word counts don’t tell the whole story.

In this guide, I’m answering exactly how many words should an 18 month old say, what counts as a “word,” when to worry, and how to help your toddler’s language development.

Let’s figure out if your child is on track.

How Many Words Should an 18-Month-Old Say? (The Real Answer)

Here’s the answer everyone wants: Most 18-month-olds say between 10 to 25 words. But here’s the full picture that matters more:

• Minimum expected: 5 to 10 words
• Average: 10 to 25 words
• Some toddlers: 50+ words
• Range of normal: Anywhere from 5 to 100+ words

The range is MASSIVE. And all of it can be normal.

What Counts as a “Word”?

This is where parents get confused. You might be undercounting your child’s words.

A word counts if:

• Your child uses it consistently to mean the same thing
• You can understand it (even if pronunciation isn’t perfect)
• It’s used intentionally to communicate

Words that COUNT:

• “Baba” for bottle (every time)
• “Dada” or “Mama”
• “Uh-oh”
• “No”
• “More”
• Animal sounds used consistently (“moo” for cow, “woof” for dog)
• Word approximations (“nana” for banana, “ba” for ball)

You don’t need perfect pronunciation. “Wawa” for water absolutely counts.

Why the Range Is So Big

Boys vs. Girls: Girls typically talk earlier than boys. This is biology, not parenting.

• Personality: Cautious kids wait until they’re sure. Outgoing kids dive right in.
• Birth order: Second and third kids often talk later (siblings talk for them!).
• Bilingual families: Kids learning two languages may have fewer words in each language but a similar total vocabulary.
• Individual development: Some kids focus on physical skills first, language second.

All of these are NORMAL variations.

What Should an 18-Month-Old Be Saying?

Let’s break down realistic expectations for speech at 18 months.

Expressive Language (What They Say)

A typical 18-month-old can: Say 10 to 25 words (might be closer to 5-10 or up to 50+)

Common first words:

• Mama, Dada
• Names of siblings or pets
• No
• Hi, bye
• More
• Food words (milk, juice, cookie)
• Favorite toys or objects (ball, book)

Use gestures along with words:

• Points while saying “that”
• Waves while saying “bye”
• Shakes head while saying “no”

May start combining words (not required yet!)

• “More milk”
• “Daddy go”
• “All done”

Only about 25% of 18-month-olds combine words. Most still use single words. Both are fine.

Receptive Language (What They Understand)

This matters MORE than word count. A typical 18-month-old understands: 50 to 100+ words (way more than they can say!)

Simple instructions:

• “Get your shoes”
• “Come here”
• “Give it to Mommy”
• “Where’s the ball?”

Questions:

• “Where’s Daddy?”
• “Do you want juice?”
• “Want to go outside?”

Body parts: Can point to nose, eyes, mouth, etc. when asked

Familiar people and objects: Knows names of family members, favorite toys, common items

If your child understands way more than they say, that’s NORMAL and actually a good sign.

Other Communication Skills at 18 Months

Non-verbal communication counts too:

• Pointing: Shows you things, points to ask for things
• Gestures: Waves, claps, blows kisses, shakes head yes/no
• Bringing you things: Shows you objects, brings you books
• Following simple commands: Can follow one-step directions
• Joint attention: Looks where you point, shows you things to share interest

These communication skills are just as important as words.

When Should You Worry About 18-Month-Old Speech?

Most late talkers are fine. But sometimes it signals a problem that needs help.

Call Your Pediatrician If:

By 18 months, your child:

• Has fewer than 5 words
• Shows no increase in words over the past few months
• Doesn’t understand simple instructions (“Come here,” “Give me the ball”)
• Doesn’t point to show you things
• Doesn’t respond to their name consistently
• Lost words they used to say (regression is always concerning)
• Doesn’t gesture (no waving, pointing, or nodding)
• Doesn’t show interest in communicating at all
• Can’t follow simple one-step commands
• Doesn’t make eye contact
• Doesn’t seem to hear well

Red Flags at Any Age

These warrant immediate evaluation:

• Regression: Lost speech or skills they used to have
• No babbling by 12 months: Should have been babbling “bababa,” “mamama”
• No gestures by 12 months: Should be waving, pointing
• No single words by 16 months
• No two-word phrases by 24 months
• Very difficult to understand by age 3
• Doesn’t respond to name by 12 months
• No interest in social interaction

Early Intervention Makes a Difference

If your child needs speech therapy, starting early gives the best results.

Don’t “wait and see” if:

• Your gut tells you something is wrong
• Your child shows multiple red flags
• Your child isn’t making progress

Early intervention services are free in the US for kids under 3. Contact your state’s Early Intervention program.

What to Do If Your 18-Month-Old Isn’t Talking Much

Your child have fewer than 10 words? Here’s what to do.

Step 1: Get a Hearing Test

This is critical. If your child can’t hear well, they can’t learn language properly.

• Call your pediatrician and ask for a hearing evaluation.
• Even if your child passed newborn hearing screening, hearing can change. Ear infections, fluid in the ears, or other issues can affect hearing.

Step 2: Evaluate Understanding

Does your child understand language even if they’re not saying much?

Test understanding:

• Ask your child to “get your shoes” without pointing
• Say “where’s the ball?” and see if they look or point
• Ask them to point to body parts
• See if they follow simple commands

If understanding is good, speech will likely catch up. If understanding is also delayed, that’s more concerning.

Step 3: Check Other Milestones

Is your child on track with other skills?

Physical milestones at 18 months:

• Walking well
• Running (maybe clumsily)
• Climbing
• Throwing a ball

Social milestones:

• Shows affection
• Plays simple pretend (feeding doll)
• Shows interest in others
• Points to show you things

If other milestones are delayed too, definitely see your pediatrician for evaluation.

Step 4: Contact Early Intervention

If your child has fewer than 5 words or shows other concerning signs, contact your state’s Early Intervention program.

• This is FREE in the US for children under 3.
• Google “[your state] Early Intervention” to find contact info.
• A speech-language pathologist will evaluate your child and provide therapy if needed.

Don’t wait for your pediatrician to refer you. You can contact Early Intervention directly.

Step 5: Keep Talking and Playing

While you wait for evaluation (or if your child is just on the slower end of normal), keep encouraging language. I’ll give you specific strategies in the next section.

How to Help Your 18-Month-Old Talk More

Whether your child is behind or you just want to encourage language, these strategies work.

1. Narrate Everything You Do

Talk constantly about what you’re doing.

Examples:

• “Mommy is making lunch. I’m getting the bread. Now I’m putting peanut butter on it.”
• “Let’s change your diaper. Lie down. Off comes the wet diaper. Here’s a clean one!”
• “We’re going outside. Let’s put on your shoes. One shoe. Two shoes.”

Why this works: Your child hears tons of words in context. They learn what words mean by hearing them repeatedly in real situations.

2. Use Simple Language

Don’t use complex sentences. Keep it short and clear.

Instead of: “Would you like to have some juice to drink?”
Say: “Want juice?”

Instead of: “We need to get ready to go to the store now.”
Say: “Time to go. Get shoes.”

Use- 1 to 3-word phrases at this age.

3. Expand on What Your Child Says

When your child says a word, add to it.

Child: “Ball!”
You: “Yes! Big ball. Blue ball. Roll the ball!”

Child: “Dada”
You: “Daddy’s home! Hi Daddy!”

This teaches grammar and vocabulary without pressure.

4. Give Choices

Offer two options and see if your child will attempt the word.

• “Do you want milk or juice?”
• “Should we read this book or that book?”
• “Do you want the ball or the car?”

Wait for a response (word, gesture, or point). Then give them what they indicated.

5. Pause and Wait

Don’t rush to give your child what they want. Create opportunities for communication.

Child points at the cup
You: “Oh, you want something. What do you want?” pause “Cup? You want your cup?” pause
Then give it to them

Even if they don’t say the word, you’re teaching them that words have power.

6. Sing Songs and Read Books

Music and books are language goldmines.

Best songs for language:

• “Wheels on the Bus”
• “If You’re Happy and You Know It”
• “Twinkle Twinkle Little Star”
• “Old MacDonald”

Do the actions (wheels turning, clapping hands, twinkling fingers).

Reading tips:

• Point to pictures and name them
• Ask “Where’s the dog?” and let child point
• Don’t worry about reading every word—talk about pictures
• Read the same books over and over (repetition helps learning)

7. Limit Screen Time

The American Academy of Pediatrics recommends:

• Under 18 months: No screen time except video calls
• 18 to 24 months: Very limited, high-quality programming WITH a parent

Screens don’t teach language. Only real human interaction does. Your child needs face-to-face conversation to learn to talk.

8. Play Interactive Games

Great games for language:

• Peek-a-boo: “Where’s Mama? Peek-a-boo!”
• Chase: “I’m gonna get you!” (encourages squeals and attempts at words)
• Ball rolling: “Roll the ball to Mommy! My turn!”
• Pretend play: Feeding dolls, playing with toy cars, and pretend cooking
• Turn-taking games: Build a block tower, taking turns, rolling a ball back and forth

These games teach that communication is back-and-forth.

9. Don’t Pressure or Correct

Never force your child to say words. Don’t say “Say ‘juice.’ Say it. Come on, say juice.” This creates pressure and can make kids shut down.

Instead, model the word and accept any attempt (gesture, sound, approximation).

Don’t correct pronunciation. If your child says “ju” for juice, respond with “Yes! Juice! Here’s your juice!” (modeling correct pronunciation without criticism).

10. Reduce Pacifier Use

If your child uses a pacifier all day, limit it to sleep times only.

Why: It’s hard to talk with a pacifier in your mouth. Plus, extended pacifier use can affect speech development.

Limit to: Nap time, bedtime, and emergencies only.

Speech Development: What Comes Next

Wondering what happens after 18 months? Here’s the typical progression.

18 to 24 Months: The Language Explosion

This is when most kids take off with language.

By 24 months, typical toddlers:

• Say 50 to 100+ words
• Start putting 2 words together consistently (“Mommy go,” “More juice”)
• Use more verbs (go, eat, play)
• Can name familiar objects
• Follow two-step commands (“Get your shoes and bring them here”)

If your child is slow at 18 months but makes progress over the next 6 months, they’re probably fine.

2 to 3 Years: Sentences Emerge

By age 3, typical kids:

• Speak in 3 to 4 word sentences
• Use pronouns (I, me, you)
• Ask questions (“What’s that?” “Where’s Daddy?”)
• Sing simple songs
• Strangers understand about 75% of what they say

When Slow Talkers Catch Up

About 70-80% of late talkers catch up by age 3 without intervention. These kids are called “late bloomers.”

Late bloomers typically:

• Understand language well
• Use gestures to communicate
• Are developing normally in other areas
• Have no hearing problems
• Make steady progress (even if slow)

The other 20-30% have true language delays that need therapy. The earlier you intervene, the better the outcome.

Bilingual Toddlers and Speech Development

Raising your child with two languages? This affects expectations. Here’s what’s normal for bilingual 18-month-olds.

Bilingual children might:

• Have fewer words in each language
• Mix words from both languages
• Have a similar total vocabulary when both languages are counted
• Take slightly longer to start combining words

Example: A bilingual 18-month-old might say 8 words in English and 7 words in Spanish (15 total), which is appropriate.

This is NOT a Delay

Learning two languages is NOT confusing for babies. Their brains are wired for it.

Bilingual children:

• Are not more likely to have speech delays
• Eventually become fluent in both languages
• Have cognitive advantages from bilingualism

If your child is bilingual and seems behind, count words in BOTH languages.

When to Worry with Bilingual Children

Use the same guidelines, but count all languages together.

Concerning signs at 18 months:

• Fewer than 5 words total (both languages combined)
• No increase in vocabulary over several months
• Poor understanding in both languages
• Not using gestures to communicate

If concerned, seek evaluation in the child’s dominant language.

Boys vs. Girls: Does Gender Affect Speech?

Yes, there are real differences on average. Research says:

Girls typically:

• Say first words earlier (around 12 months)
• Have a larger vocabulary at 18 months
• Start combining words sooner
• Speak more clearly earlier

Boys typically:

• Say first words a bit later (13-14 months)
• Have a smaller vocabulary at 18 months
• Take longer to combine words
• Are harder to understand initially

The gap usually closes by age 3-4.

What This Means for Your Son

If your 18-month-old boy has 10 words while his female cousin has 30 words, this might just be a normal gender difference.

Don’t panic if your son is on the lower end of normal.

But don’t ignore red flags just because “boys talk later.” If your son shows concerning signs, get an evaluation.

Your 18-Month-Old is Developing on Their Own Timeline

Comparing your toddler to others can be challenging. But try not to stress.

How many words should an 18-month-old say? Anywhere from 5 to 50 or more can be normal. The average is 10 to 25 words.

What matters more than word count:

• Does your child understand language?
• Are they communicating (words, gestures, pointing)?
• Are they making progress?
• Do they show interest in communicating?

If yes to these questions, your child is probably fine even with fewer words.

Keep talking to your child. Keep reading. Keep playing. Keep encouraging. Language will come.

And if you’re worried? Trust your gut. Get an evaluation. Early intervention changes lives.
