Every child develops at their own pace. Some toddlers are stringing together full sentences before their second birthday, while others take a little more time to find their words. That range is completely normal, and it can make it tricky for parents to figure out whether their child is just a “late talker” or whether something else might be going on.
The good news? You don’t have to figure it out alone. Understanding key speech and language milestones can help you recognize when your child might benefit from a little extra support. And if they do, early intervention can make a world of difference.
Here are the most common signs that your toddler may need speech therapy, plus what you can do about it.
First, a Quick Note: Speech and Language Are Different Things
Before we get into the signs, it helps to understand the difference between speech and language, because the two terms get used interchangeably all the time.
Speech refers to the physical production of sounds. It involves how your child uses their mouth, tongue, lips, and jaw to form words. A child with a speech delay might try to talk but be very difficult to understand.
Language is the broader system of communication, including understanding what others say (receptive language) and expressing thoughts, needs, and ideas (expressive language). A child with a language delay might speak clearly but have a very limited vocabulary or struggle to form sentences.
A toddler can have a speech delay, a language delay, or both. Knowing which one your child is dealing with helps a speech-language pathologist (SLP) create the right plan for them.
Key Speech and Language Milestones to Watch For
While every child is unique, there are general milestones that most children reach within certain age windows. These aren’t rigid deadlines, but they’re helpful benchmarks. If your child is consistently falling behind in several of these areas, it may be worth having a conversation with a pediatric speech therapist.
By 12 Months
Most babies start babbling with a variety of sounds well before their first birthday. By around 12 months, you’d typically expect your child to be using simple gestures like pointing and waving bye-bye, responding to their name, and beginning to say their first word or two (even if they’re not perfectly clear). If your baby isn’t babbling, doesn’t seem to respond to sounds or voices, or isn’t using any gestures to communicate, those are signs worth paying attention to.
By 18 Months
By a year and a half, most toddlers have a vocabulary of around 20 words and are actively trying to imitate new words they hear. They should be able to understand simple requests like “give me the ball” or “where’s your shoe?” If your toddler relies almost entirely on gestures instead of vocalizing, or their word count is significantly below what you’d expect, a speech evaluation could be helpful.
By 2 Years
This is a big milestone window. By age two, most children have a vocabulary of around 50 words or more and are starting to combine words into simple two-word phrases like “more milk” or “daddy go.” You (and other regular caregivers) should be able to understand roughly half of what your child says. If your two-year-old is still mostly using single words, repeating only a handful of sounds, or isn’t putting words together at all, it’s a good idea to schedule an evaluation.
By 3 Years
By three, your child’s vocabulary should be expanding quickly, and they should be forming three-word (or longer) sentences. Familiar listeners should understand about 75% of what they say. They should also be able to follow simple two-step directions, like “pick up the toy and put it on the table.” If strangers can’t understand most of what your three-year-old says, or if your child struggles to form basic sentences, professional support could make a meaningful difference.
Common Signs Your Toddler May Benefit From Speech Therapy
Beyond the milestone markers above, here are some of the most common red flags that parents and caregivers notice in everyday life.
They’re Hard to Understand
If your child is talking but people outside your household can’t make out what they’re saying, that could point to an articulation issue. It’s normal for toddlers to mispronounce certain sounds (that’s part of learning), but if they’re using a very limited set of sounds to form all their words, or if even you have trouble understanding them past age two, it’s worth looking into.
They Get Frustrated When Trying to Communicate
Toddlers who understand the world around them but can’t express their needs verbally often become visibly frustrated. You might notice more tantrums, hitting, biting, or screaming, not because of behavioral issues, but because they literally can’t get their message across. If your child seems to know what they want to say but can’t find the words, that frustration is a meaningful signal.
They Don’t Respond to Their Name or Simple Directions
If your toddler doesn’t consistently turn when you call their name, or can’t follow simple instructions like “come here” or “give me the cup,” that could indicate a receptive language concern. This doesn’t automatically mean there’s a serious issue, but it’s something a speech-language pathologist can evaluate. In some cases, difficulty understanding language can also be connected to auditory processing challenges, so an audiological screening might be recommended as well.
Stuttering That Persists
It’s common for toddlers to go through a brief period of stuttering as they learn to put longer sentences together, usually around age two or three. For most kids, this resolves on its own. But if your child has been stuttering for more than a few months, if they seem physically tense or struggle to get words out, or if they start avoiding talking altogether, a speech therapist can help determine whether intervention is needed. Learn more about how we approach fluency disorders and stuttering.
Difficulty With Feeding or Swallowing
This one surprises a lot of parents, but feeding challenges and speech development are closely connected. The same muscles your child uses to chew and swallow are the ones they use to produce speech sounds. If your toddler has ongoing difficulty with feeding, such as trouble transitioning to solids, frequent gagging, or messy eating that doesn’t improve with age, a speech-language pathologist who specializes in feeding therapy can help address both areas. We also work with children experiencing feeding and food aversions.
Limited Social Communication
Communication isn’t just about words. It also involves eye contact, taking turns in a conversation, reading social cues, and engaging with others. If your child avoids eye contact, doesn’t seem interested in interacting with other kids, or has difficulty with basic back-and-forth exchanges, a speech-language evaluation can help identify whether there’s an underlying communication challenge that needs support.
Why Early Intervention Matters
If you’ve noticed any of the signs above, the most important thing to know is this: earlier is always better when it comes to speech therapy.
Young children’s brains are incredibly adaptable. The earlier a speech or language concern is identified, the easier it is to address and the better the long-term outcomes tend to be. Children who receive early intervention often catch up to their peers more quickly and are better prepared for the social and academic demands of school.
On the other hand, taking a “wait and see” approach can sometimes mean missing a critical window where therapy would have the most impact. If something feels off, trust your instincts. Getting an evaluation doesn’t commit you to anything. It just gives you information, and that information can be incredibly empowering.
What to Expect From a Speech and Language Evaluation
If you decide to schedule an evaluation, here’s what typically happens. A licensed speech-language pathologist will spend time observing your child, interacting with them through play, and assessing their speech sounds, vocabulary, comprehension, and overall communication skills. They’ll also ask you questions about your child’s developmental history and your specific concerns.
Based on what they find, the SLP will let you know whether therapy is recommended and what a treatment plan might look like. If your child does need support, sessions are typically fun, play-based, and tailored to your child’s personality and needs. The therapist will also give you strategies to use at home so your child gets consistent support between sessions. Have more questions about the process? Check out our FAQ page.
What You Can Do at Home in the Meantime
Whether or not your child ends up needing formal therapy, there are plenty of things you can do right now to support their speech and language development at home.
Talk to your child throughout the day. Narrate what you’re doing, describe what they’re playing with, and expand on what they say. If your toddler says “truck,” you might respond with “yes, that’s a big red truck!”
Read together every day. Books are one of the best tools for building vocabulary and language comprehension. Point to pictures, ask simple questions, and let your child turn the pages.
Avoid correcting their pronunciation directly. Instead of saying “that’s wrong,” simply model the correct version. If your child says “goggy,” respond with “yes, that’s a doggy!” This keeps communication positive and encouraging.
Give them time to respond. It can be tempting to jump in and finish your child’s sentences, but giving them a few extra seconds to process and respond helps build their confidence and independence.
Limit screen time. Interactive, face-to-face communication is far more valuable for language development than passive screen exposure. Prioritize real conversations, singing, and play.
