A 20-month-old who isn’t talking yet is behind the expected timeline, but that doesn’t automatically mean something is wrong. By 18 months, at least 75% of children can say three or more words beyond “mama” and “dada.” If your child hasn’t reached that point two months later, it’s worth paying attention to what else they can and can’t do, because the words themselves are only part of the picture.
What 20-Month-Olds Are Expected to Do
In 2022, the CDC and the American Academy of Pediatrics revised their developmental milestone checklists. The old lists used the 50th percentile, meaning only half of children would hit the milestone by that age. The updated checklists set the bar at the 75th percentile, so the milestones now reflect what most children can do, not just the average child. Under these updated guidelines, an 18-month-old is expected to try saying at least three words besides “mama” or “dada” and follow simple one-step directions without gestures, like handing you a toy when you say “give it to me.”
By 24 months, the expectations jump significantly. Children are generally combining two words together (“more milk,” “daddy go”) and using a vocabulary of around 50 words. At 20 months, your child falls right between these two checkpoints. If they have no words at all, or only one or two, they’re falling short of the 18-month milestone and it makes sense to look more closely at what’s going on.
Understanding Matters More Than Talking
The single most important thing to pay attention to right now is whether your child understands language, even if they aren’t producing it. Speech-language experts call this receptive language, and it’s a better predictor of long-term outcomes than how many words your child says. A child who can point to objects when you name them, follow simple instructions (“go get your shoes”), look at things you point to, and respond to their name is demonstrating that their language system is developing, even if the talking part hasn’t caught up yet.
If your child seems to understand what you say, they are more likely to catch up on their own. Children who don’t seem to understand what others are saying are at higher risk for a true language delay rather than just being a late talker.
Late Talkers vs. Language Delays
The term “late talker” specifically describes a toddler who has limited spoken vocabulary but otherwise develops normally: they understand language, they use gestures, they make eye contact, they play with toys in typical ways. Many late talkers do eventually catch up. Research estimates vary widely, but somewhere between 60% and 90% of late talkers reach normal language levels by preschool age. That’s a reassuring range, but it also means a meaningful percentage don’t catch up without help.
The challenge is that there’s no reliable way to predict at 20 months which children will bloom on their own and which ones will continue to struggle. That uncertainty is exactly why early evaluation matters. Getting assessed doesn’t commit you to anything, but it does give you a clearer picture of where your child stands and whether intervention would help.
Signs That Point to Something More
Delayed speech on its own is common and often benign. But certain patterns alongside the missing words raise the level of concern. Watch for whether your child:
- Doesn’t share interest with you. By 19 to 20 months, children are typically eager to show you things, point at objects to get your attention, and look back and forth between you and something interesting. A child who doesn’t do this is missing a key social communication milestone.
- Doesn’t use gestures. Pointing, waving, shaking their head “no,” and reaching to be picked up are all ways toddlers communicate before and alongside words. A child with very few gestures and very few words has a different profile than a child who gestures constantly but just isn’t talking yet.
- Doesn’t respond to their name consistently. Occasional ignoring is normal. Rarely or never turning when called is not.
- Doesn’t seem interested in other people. This includes not making eye contact, not smiling back at you, or preferring to play alone without checking in.
These signs overlap with early indicators of autism spectrum disorder. Most pediatricians screen for autism using a parent questionnaire called the M-CHAT-R, typically at the 18- and 24-month well-child visits. Scores of 0 to 2 are considered low risk, 3 to 7 are medium risk and trigger follow-up questions, and 8 to 20 are high risk and warrant immediate referral for a diagnostic evaluation. If your child hasn’t been screened yet, ask your pediatrician at the next visit.
Ear Infections and Hidden Hearing Issues
One commonly overlooked cause of speech delay is fluid in the middle ear, which can linger after ear infections and reduce hearing without obvious symptoms. Your child might not seem to be in pain or pulling at their ears, but the muffled input can interfere with language development during a critical window. Research has shown that children with histories of repeated ear infections perform more poorly on language measures than their peers, with particularly strong effects on their ability to distinguish speech sounds.
The concern isn’t just about hearing loss in the traditional sense. Even temporary, mild reductions in sound clarity can limit a toddler’s access to the language around them during the months when their auditory system is rapidly developing. If your child has had multiple ear infections, or if you’ve noticed they seem to ignore you more than expected, a hearing evaluation is a straightforward and important step.
What an Evaluation Looks Like
A speech-language evaluation for a toddler this age is not a stressful test. A speech-language pathologist will typically observe your child playing, interact with them directly, and ask you detailed questions about what your child does at home. They’ll assess both what your child understands and what they produce, looking at sounds, words, gestures, and how your child communicates their wants and needs.
You don’t need a referral from your pediatrician to get started in most cases. In the United States, every state has an early intervention program for children under 3, and you can self-refer by contacting your state’s program directly. These evaluations are free, and if your child qualifies, therapy services are provided at low or no cost. The earlier you start, the more effective intervention tends to be, so there’s little downside to requesting an evaluation even if your child might catch up on their own.
What You Can Do at Home Right Now
While you’re waiting for an evaluation or deciding whether to pursue one, there are specific strategies that support language development. These aren’t replacements for professional help if it’s needed, but they create the kind of language-rich environment that benefits all toddlers.
The most effective technique is expanding on whatever your child gives you. If they point at a dog, say “Dog! Big dog. The dog is running.” If they say “ba” for ball, respond with “Ball! You want the ball. Here’s the ball.” You’re not correcting them or asking them to repeat after you. You’re modeling the words that match what they’re already paying attention to, which is when toddlers learn language best.
Narrate what you’re doing together throughout the day. “I’m putting on your sock. One sock, two socks. Now your shoes.” Keep sentences short and slightly above your child’s current level. If they use zero words, use one- and two-word phrases. If they use single words, model two- and three-word combinations. Read books together, but don’t worry about reading every word on the page. Talk about the pictures, point things out, and let your child turn pages and lead the interaction.
Resist the urge to quiz your child by constantly asking “What’s this?” or “Say ball.” Pressure to perform tends to make reluctant talkers retreat further. Instead, create situations where communication is naturally motivating. Put a favorite snack in a clear container they can’t open, so they have a reason to come to you. Offer choices (“apple or banana?”) and pause to give them time to respond, even if the response is just a point or a sound.
How to Think About the Timeline
Between 20 and 24 months, language often explodes. Many parents of late talkers describe a sudden jump where their child goes from a handful of words to dozens within weeks. If your child has strong understanding, uses gestures, and is socially engaged, this burst may be right around the corner.
That said, a “wait and see” approach has real risks. If your child does have a language disorder or another developmental difference, the months between now and age 3 are when intervention is most effective because the brain is at its most adaptable. Contacting your state’s early intervention program costs nothing and takes very little time. If the evaluation shows your child is developing normally, you’ll have peace of mind. If it reveals a delay, you’ll have caught it at the best possible moment.
