If your child consistently misses age-based speech milestones, contact your pediatrician now and request both a hearing test and a referral to a speech-language pathologist (SLP). You do not need to wait for a formal diagnosis to ask for help. The CDC’s developmental milestones, the American Academy of Pediatrics (AAP), the American Speech-Language-Hearing Association (ASHA), and Hopkins Medicine all agree: earlier evaluation leads to better outcomes.
Here is what to do right now if you are concerned:
- Call your pediatrician and describe the specific behaviors you have noticed.
- Request a hearing screening at the same visit. Hearing loss is one of the most common and treatable causes of speech delays.
- Gather examples before the appointment: short video clips, a list of words your child uses, and notes on how often they communicate.
Pro Tip: Trust your instincts. If something feels off, it probably warrants a conversation with your child’s doctor. According to Hopkins Medicine, an evaluation is never “too early” when you have a genuine concern.

Speech vs. language: why the difference matters for your child’s evaluation
These two terms are often used interchangeably, but they describe different skills, and clinicians assess them separately.
Speech refers to the physical production of sounds. It covers articulation (how clearly sounds are formed), fluency (the rhythm and flow of talking), and voice quality. A child who says “wabbit” instead of “rabbit” has a speech issue.
Language is about meaning and communication. It includes:
- Receptive language: what your child understands (following a two-step direction, pointing to named objects)
- Expressive language: what your child communicates (words, phrases, gestures, facial expressions)
A child can have strong receptive language but limited expressive output, or vice versa. That distinction shapes which specialist gets involved. An audiologist rules out hearing loss first. An SLP then evaluates both speech and language in depth.
“Children who have trouble understanding what others say (receptive language) or difficulty sharing their thoughts (expressive language) may have a language disorder.”
— NIDCD, National Institute on Deafness and Other Communication Disorders
Pro Tip: Before your appointment, write down one example of something your child understands but cannot say, and one example of something they say but may not fully understand. That two-sentence note gives your pediatrician a clearer picture than a general “I’m worried about their speech.”
Age-based milestones you can check right now
The table below draws from ASHA’s early identification guidance and the NIDCD. Use it as a quick reference, not a pass/fail test.
| Age | Speech and language milestones |
|---|---|
| — | Startles at sounds; coos and makes soft vowel sounds |
| — | Babbles with consonant sounds (ba, da, ma); responds to name |
| — | Uses varied babble; waves, points, or uses gestures; may say “mama” or “dada” |
| 12–18 months | Says 1 word meaningfully; follows simple one-step directions |
| 18–24 months | Vocabulary grows to around 50 words; begins combining two words (“more milk”) |
| 2–3 years | Uses 2–3 word phrases; strangers understand about 70% of speech |
| 3–5 years | Tells simple stories; uses sentences of 4–5 words; strangers understand about 90% of speech by age 4 and nearly all by kindergarten |
A typical child reaches 50 words and two-word phrases by 24 months. If your two-year-old is well below that count, that is a concrete signal to call your pediatrician this week.
Intelligibility benchmarks from Hopkins Medicine: strangers should understand about 70% of a two-year-old’s speech, 80% at age 3, 90% at age 4, and nearly 100% by kindergarten.
A note on normal variation: Bilingual children may mix languages or hit expressive milestones slightly differently. Count words across both languages when tracking vocabulary totals. Late bloomers do exist, but about 1 in 5 children talk later than peers, and family history or combined delays still warrant specialist input.
Red flags that mean you should call today, not next month
Some signs do not require a wait-and-see approach. These warrant a prompt call to your pediatrician regardless of your child’s age:
-
No babbling by 9–12 months
-
No single words by 16–18 months
-
No two-word phrases by 24 months
-
Loss of previously mastered words or skills at any age — this is the most urgent sign
-
Not pointing, waving, or using gestures by 12 months
-
Limited eye contact or social engagement alongside speech concerns
-
Difficulty understanding simple directions by 18 months
On autism and speech delay: These are not the same thing, though they can overlap. Children with isolated speech delays typically engage socially, make eye contact, and use gestures to communicate. Children with autism spectrum disorder (ASD) often show reduced joint attention and social reciprocity alongside language differences. If you notice both reduced social engagement and limited speech, mention both to your pediatrician.
What causes speech and language delays?
Understanding the likely cause helps you give your child’s doctor a useful history. Common contributors include:
- Hearing loss, including temporary loss from recurrent ear infections (otitis media)
- Oral-motor difficulties, such as tongue-tie (ankyloglossia) or childhood apraxia of speech
- Developmental disorders, including ASD or developmental language disorder (DLD)
- Neurological or genetic conditions that affect motor planning or cognitive development
- Limited language exposure, including reduced one-on-one conversation time
Risk factors that warrant earlier referral include a family history of speech or language delays, premature birth, recurrent ear infections (three or more in a year), and any existing medical diagnosis affecting development.
Pro Tip: Before your appointment, jot down how many ear infections your child has had in the past 12 months and whether any close relatives had speech therapy as children. That history takes two minutes to write and can meaningfully shape the referral your pediatrician makes.
What happens during an evaluation: pediatrician, audiologist, and SLP
The evaluation pathway typically moves in three steps, and knowing what to expect at each one makes the process far less stressful.
Step 1: Pediatrician screening. Your child’s doctor uses a standardized developmental screening tool at well-child visits (the AAP recommends screening at 9, 18, and 24–30 months). If concerns arise, they refer you onward.
Step 2: Hearing test with an audiologist. Because hearing loss can directly cause speech delays, audiology testing is recommended whenever speech concerns exist. The test is painless and can be done even in infants.
Step 3: SLP evaluation. A speech-language pathologist conducts a comprehensive assessment that covers:
- Receptive language (what your child understands)
- Expressive language (what they say and how)
- Articulation and phonology
- Oral-motor function
- Play-based observation
- Standardized testing appropriate for age
For children under 3, your pediatrician can also refer directly to your state’s early intervention program under IDEA Part C, which provides free evaluations and services at home or in community settings.
What to bring to your appointment:
- Short video or audio clips of your child’s typical speech (30–60 seconds, spontaneous play)
- A written list of words your child uses consistently
- Notes on missed milestones with approximate dates
- Medical history: ear infections, illnesses, hearing screenings
- Family history of speech, language, or learning differences
Pro Tip: Ask your pediatrician directly: “Can you refer us to early intervention?” You do not need a formal diagnosis to qualify for an evaluation under IDEA Part C.
How early intervention and speech therapy actually help
Starting therapy early matters. Hopkins Medicine notes that early intervention reduces later academic and behavioral risks by targeting expressive language before frustration-driven behaviors take hold.
Therapy formats vary depending on your child’s age and needs:
- Clinic-based SLP sessions: structured, one-on-one or small group
- In-home early intervention: for children under 3, often provided at no cost through IDEA Part C
- Parent-implemented strategies: the SLP coaches you to use specific techniques during daily routines
- Teletherapy: increasingly available and effective for mild-to-moderate delays
“Early intervention services can make a significant difference in a child’s ability to learn new skills and overcome challenges.”
— Nemours KidsHealth
Realistic short-term progress markers include more frequent gestures, first spontaneous words, longer utterances, and reduced frustration during communication attempts. Progress is incremental. A child who starts therapy at 18 months will not speak in full sentences by 20 months, but they will likely show measurable gains in gesture use and sound variety within weeks. For school-age children, services shift to an IEP (Individualized Education Program) through the school district.
Everyday strategies that genuinely support language at home
You do not need to wait for a therapy appointment to start helping. These evidence-based techniques work during ordinary moments.
- Narrate your day. Describe what you are doing as you do it: “I’m washing your hands. The water is warm.”
- Comment more than question. Instead of “What’s that?” say “Oh, a dog! The dog is running.” This reduces pressure and models language naturally.
- Expand what your child says. If they say “ball,” you say “Yes, big red ball!” You are adding one layer, not a lecture.
- Use simple, clear sentences. Match your language level to just above your child’s current output.
- Pause and wait. After asking a question or modeling a word, give your child 5–10 seconds to respond before jumping in.
- Read together daily. Point to pictures, name objects, and let your child turn pages. Even 10 minutes makes a difference.
- Sing. Songs with repetition and movement (think “Wheels on the Bus”) build phonological awareness and vocabulary simultaneously.
Pro Tip: Pick one routine, such as bath time or the car ride home, and commit to narrating it every day for two weeks. Consistency in a low-pressure setting often produces the first new words parents notice.
For bilingual households: count expressive vocabulary across both languages. Bilingualism alone does not cause speech delay, and cross-language totals give a more accurate picture of your child’s development.
If your child has limited attention or sensory sensitivities, keep sessions short (2–5 minutes), follow their lead, and use preferred toys or activities as the context for language modeling.
How to track progress and prepare for appointments
Organized documentation makes every appointment more productive. Clinicians can act on specific, dated observations far more effectively than general concerns.
Build a simple tracking record:
- Date-stamped video clips (30–60 seconds of spontaneous play in a familiar setting, capturing both your child’s attempts and your responses)
- A word list updated weekly, noting new words and any words that have disappeared
- Behavioral notes: how often your child initiates communication, whether speech is spontaneous or only prompted
- Medical history: ear infection frequency, any hearing screenings, relevant diagnoses
- Family history: relatives who had speech therapy or language-based learning differences
Questions to bring to your pediatrician or SLP:
- “Is my child’s vocabulary age-appropriate for their stage?”
- “Should we test their hearing before the SLP evaluation?”
- “Can you refer us to early intervention under IDEA Part C?”
- “What specific milestones should I watch for over the next three months?”
- “How often should we follow up if we take a watchful-waiting approach?”
Pro Tip: Capture spontaneous speech, not prompted speech. A clip of your child playing independently or interacting with a sibling gives the SLP far more diagnostic information than a recording where you are asking them to repeat words.
The Baby Bare Essentials planner includes dedicated milestone tracking pages where you can log speech observations, appointment notes, and questions for your child’s care team, all in one organized place.
For parents planning ahead as their child approaches school age, understanding how to evaluate your child’s academic learning needs can help you prepare for the transition from early intervention to school-based services.
When to seek help: clear age-based action cues
Use this as your decision guide:
-
Act immediately if your child loses words or skills they previously had, at any age.
-
Call this week if there is no babbling by 9–12 months, no single words by 16–18 months, or no two-word phrases by 24 months.
-
Schedule soon if your child’s vocabulary is below 50 words at 24 months or strangers cannot understand most of their speech by age 3.
-
Mention at the next well visit if you notice limited gestures, reduced eye contact, or a preference for solitary play alongside speech concerns.
Your action flow:
- Observe specific behaviors and note dates.
- Document with video clips and a word list.
- Call your pediatrician and describe what you have observed.
- Request a hearing test at the same visit or as a first referral.
- Ask for early intervention or SLP referral based on the outcome.
The 50-word vocabulary threshold at 24 months is one of the clearest, most clinician-cited benchmarks for deciding whether to refer. If your child is approaching that age and well below that count, do not wait for the next scheduled well visit.

Early identification of speech delays gives children the best chance at closing developmental gaps before school age, and a hearing test is always the right first step.
| Point | Details |
|---|---|
| Know the clearest milestone | A typical child uses about 50 words and two-word phrases by 24 months; falling short warrants a call to your pediatrician. |
| Regression is urgent | Loss of previously mastered words or skills at any age requires immediate medical evaluation, not watchful waiting. |
| Hearing test comes first | Hearing loss is a common, treatable cause of speech delays; request a screening at your first concern visit. |
| Early intervention is free under 3 | IDEA Part C provides no-cost evaluations and therapy for children under 3; ask your pediatrician for a direct referral. |
| Babybareessentials helps you stay organized | The planner’s milestone tracking pages let you log speech observations and appointment notes in one place, ready for any clinician visit. |
What I want every worried parent to hear
Parental worry about a child’s speech is one of the most common concerns I see parents carry into pediatric appointments, and it is also one of the most actionable. The anxiety is real. So is the tendency to second-guess yourself, especially when well-meaning relatives say “Einstein didn’t talk until he was three” or “boys are just slower.”
Here is what those reassurances miss: evaluation is not a verdict. Getting your child assessed does not mean something is wrong. It means you are paying attention. And if the SLP finds that your child is developing typically, you leave with peace of mind and a clearer picture of what to watch for. If they find a delay, you have started the process at exactly the right time.
The families who struggle most are not the ones who sought evaluation too early. They are the ones who waited a year because someone told them not to worry, and then spent that year watching their child grow more frustrated trying to communicate without the tools to do so.
Trust what you observe. You know your child better than any checklist does. And getting checked is always the right call when your gut says something is off.

FAQ
What are the first signs of a speech delay?
The earliest signs include no babbling by 9–12 months, no single words by 16–18 months, and no two-word phrases by 24 months. Limited gestures (no pointing or waving by 12 months) are also an early indicator worth raising with your pediatrician.
At what age is a speech delay concerning?
Any missed milestone warrants a conversation with your child’s doctor; the clearest threshold is 24 months, when most children should have a vocabulary of about 50 words and be combining two-word phrases. Loss of previously mastered words is urgent at any age.
What is a red flag for speech delay?
Regression, meaning a child stops using words they previously said, is the most urgent red flag and requires immediate evaluation. Other high-priority signs include no babbling by 12 months, no words by 18 months, and limited social engagement alongside speech concerns.
How do you know if a speech delay is related to autism?
Children with isolated speech delays typically engage socially, make eye contact, and use gestures to communicate. Children with ASD often show reduced joint attention and social reciprocity alongside language differences. If you notice both, mention both to your pediatrician so they can screen for both.
Can I request an early intervention evaluation without a diagnosis?
Yes. Under IDEA Part C, any parent can request a free developmental evaluation for a child under 3 without a prior diagnosis. Ask your pediatrician for a referral, or contact your state’s early intervention program directly.
