Most children say their first real words around their first birthday, but the road to talking starts months earlier and unfolds gradually through age two. A child who isn’t speaking yet may still be right on track, or they may need a closer look. The difference often comes down to age, the specific signs you’re seeing, and whether your child is communicating in other ways.
What Happens Before First Words
Talking doesn’t begin with words. It begins with sounds, and those sounds follow a predictable pattern. In the first three months, babies coo and make soft pleasure sounds. By four to six months, they start babbling with consonant sounds like “p,” “b,” and “m,” and they babble differently when they’re happy versus upset.
Between five and ten months, babies typically begin what’s called canonical babbling: repeating syllable-like combinations such as “babababa” or “mamama.” This is a significant milestone. Research across multiple languages shows this type of babbling consistently appears before 10 months, and babies who don’t reach it by 10 to 12 months tend to have smaller vocabularies at 18, 24, and 30 months. Babbling on time doesn’t guarantee smooth speech development later, but its absence is one of the earliest signals worth paying attention to.
Month-by-Month Speech Milestones
By their first birthday, most children have one or two words. These are often “mama,” “dada,” “hi,” or the name of a pet or favorite object. The words may not sound perfect, but your child uses them consistently to mean the same thing.
At 15 months, most kids say one to two words beyond “mama” and “dada.” By 18 months, that grows to three or more words. These numbers can feel surprisingly low if you’re comparing your child to a neighbor’s toddler who seems to narrate everything, but the range of normal is wide during this period. Some 18-month-olds say three words. Others say 50.
The biggest leap comes between 18 and 24 months. By age two, most toddlers are saying many more words and stringing two words together into simple phrases like “more milk,” “daddy go,” or “big truck.” This shift from single words to two-word combinations is one of the milestones pediatricians watch most closely.
Understanding Comes Before Speaking
One thing that often reassures parents is realizing that their child understands far more than they say. Receptive language (what your child comprehends) runs well ahead of expressive language (what they produce) throughout the first two years.
Between 7 and 11 months, most babies already recognize their own name, know words for common objects like “cup” or “shoe,” and start responding to simple requests. By 12 to 17 months, a child typically understands short phrases like “put the ball in the box” and can answer simple questions by nodding, shaking their head, or going to get something you asked for. Between 18 and 23 months, children begin understanding action words (clap, sit, jump), can point to body parts when asked, and answer yes-or-no questions.
A child who isn’t saying many words yet but clearly understands what you’re saying, follows directions, and communicates through pointing and gestures is in a very different situation than a child who doesn’t seem to understand language at all. Both deserve attention, but the second scenario is more urgent.
Signs That Warrant an Evaluation
A few specific red flags stand out at particular ages. If your child is not pointing or using any gestures by 12 months, that’s worth discussing with your pediatrician. By 24 months, the two key warning signs are the absence of two-word spontaneous phrases and the inability to follow simple commands like “sit down” or “come here.”
At any age, two things should prompt immediate concern: inconsistent or absent responses to sound (your child doesn’t startle at loud noises, doesn’t turn toward voices, or seems to hear sometimes but not others), and any loss of skills your child previously had. A toddler who was saying words and then stops, or who was socially engaged and then withdraws, needs evaluation regardless of age.
Hearing problems are one of the most common and most treatable causes of speech delay. Frequent ear infections can temporarily muffle sound during the exact months when a child’s brain is learning to decode language. If your child has had multiple ear infections, mention it specifically when discussing speech concerns.
What About Bilingual Children?
Growing up with two languages does not cause speech delay. This is one of the most persistent misconceptions in child development, and the science is clear on it. Bilingual children hit their speech milestones on the same timeline as monolingual children and are no more likely to be diagnosed with a language disorder.
The confusion arises because a bilingual toddler may know fewer words in each individual language than a monolingual peer. But when you add up the words they know across both languages (removing duplicates like “dog” and “perro”), their total vocabulary is about the same. Measuring a bilingual child with a test designed for one language will almost always make them look behind. If your child is learning two languages, make sure any evaluation accounts for both.
How Reading and Talking Build Vocabulary
The amount of language your child hears matters enormously, and one of the simplest ways to increase it is reading together. Even a single reading of a picture book can help a child learn a new word. On days when parents read with their child, both parent talk and child talk increase significantly compared to non-reading days.
Starting shared reading as early as six months has been linked to stronger vocabulary by 12 months. Children in homes where book-sharing happens at least once a day hear an estimated 1.4 million more words over their first five years than children who aren’t read to, and that figure only counts the words printed on the page. It doesn’t include all the conversation that happens around the book: naming pictures, asking questions, making animal sounds. The frequency of early reading predicts vocabulary differences in preschoolers even after accounting for differences in parent education and income.
You don’t need special books or techniques. Pointing at pictures, naming what you see, and letting your child turn the pages all count. Narrating daily life works too: describing what you’re cooking, what you see on a walk, what your child is doing as they play.
How to Get a Free Evaluation
If something feels off, you don’t need to wait for your pediatrician to bring it up, and you don’t need a doctor’s referral. Every state has a publicly funded early intervention program that provides free or reduced-cost evaluations and services for children under three. You can call your state’s program directly and say you have concerns about your child’s development and would like an evaluation to determine eligibility.
If your child is three or older, the process shifts to the public school system. You can call any local public elementary school, even if your child doesn’t attend, and request an evaluation for preschool special education services. Ask for the special education director if the person answering isn’t familiar with the process.
Eligibility for services is based on the evaluation results, not on a diagnosis. Many children who qualify for speech therapy through these programs catch up quickly, especially when intervention starts early. The gap between “let’s keep an eye on it” and an actual evaluation can be months of lost time during a period when a child’s brain is developing rapidly.
