If your child is missing several speech or language milestones, has lost skills they once had, or you simply feel something is off, the answer is to act now rather than wait. Guidance from ASHA and the CDC points to 18 to 24 months and age 2 as key checkpoints, and Early intervention before age 3 is generally considered beneficial for clearer results. Call your pediatrician, request a developmental screening, or contact your state early intervention program this week.
TL;DR:
- Most children should have at least 50 words by 24 months, with the ability to combine two words, signaling typical language development.
- Regression or loss of previously acquired words or social skills in any age range requires immediate evaluation, regardless of the child's age.
- Early intervention within the first three years is most effective, but children beyond age 3 can still benefit from speech therapy with timely assessment.
- Speech or feeding difficulties, such as unclear speech or swallowing issues, should prompt a referral for an evaluation without delay.
- Starting the referral process early ensures access to services, especially since waitlists can be long, and progress is tracked through skill building and daily routines.

Age-based milestones parents can use to judge progress
Every child develops at their own pace, but pediatric speech and language specialists track certain windows to see how skills are building. Think of these ranges as guideposts, not a strict test your child must pass on a specific day.
- Birth to 12 months: cooing and babbling develop, your baby responds to their name, and gestures like reaching or waving begin to appear.
- 12 to 18 months: first words emerge, gestures such as pointing become common, and the CDC notes that children this age are typically attempting several words.
- 18 to 24 months: word counts expand quickly, children begin combining two words together, and many toddlers reach 50 or more words by the end of this stretch.
- 2 to 3 years: children combine words into short phrases, intelligibility improves so that familiar listeners understand more of what they say, and back-and-forth exchanges start to feel like real conversations.
- 3 to 5 years: articulation sharpens, sentences lengthen, and children build the early language and listening skills that support reading and classroom participation.
A single missed milestone rarely signals a problem on its own. What matters more is a pattern: several skills missing at once, or a skill your child once had that has quietly disappeared. That second scenario, often called regression, deserves prompt attention regardless of age.
Red flags and warning signs that mean seek evaluation now
Some signs call for a faster response than others. If you notice any of the following, don't wait for the next well-child visit to bring it up.
- Loss of words or social skills your child previously had, since regression is one of the clearest signals something needs a closer look.
- No babbling, pointing, or attempts at words by the expected ages, paired with very limited back-and-forth interaction with caregivers.
- Speech that stays hard to understand for the child's age, since intelligibility should climb steadily as children move from toddlerhood into the preschool years.
- Feeding or swallowing difficulties, including frequent coughing, choking, or strong food refusal, which often overlap with a referral to a speech-language pathologist.
Pro Tip: Keep a simple log of what you notice, with dates and a few short videos, so your pediatrician or evaluator can see real examples instead of relying on memory alone.
How to get an evaluation and what the process looks like
Getting started is more straightforward than most parents expect, and moving quickly protects your spot in line for services.
- Tell your pediatrician exactly what you're noticing and ask directly for a developmental screening.
- Request a hearing check if speech delay is suspected, since hearing issues can look like a language delay.
- Ask for a referral to an ASHA-certified speech-language pathologist, who will typically combine a parent interview, direct observation, and standardized measures during a formal evaluation.
- Contact your state's early intervention program for children under 3, since IDEA Part C requires an evaluation and written plan, called an IFSP, within 45 days of referral, with services starting within 30 days after that.
Waitlists exist in many areas, so starting the referral process as soon as you have a concern gives your family more options and more time.
What speech therapy usually involves and how progress is measured
Therapy goals shift with age and need: building vocabulary and sentence structure in toddlers, sharpening articulation in preschoolers, and supporting social communication or feeding and oral-motor skills when those are part of the picture.
- Sessions may happen in a clinic, at home through early intervention, or through teletherapy, and a team approach is common when feeding or medical concerns are involved.
- Frequency depends on the child's needs, with progress tracked through skill acquisition, participation in everyday routines, and changes parents report at home.
- Interprofessional care, meaning medical, nutritional, and therapy teams working together, has been linked to better outcomes for pediatric feeding disorders than a single specialist working alone.
Consistent home practice matters. Parents who reinforce skills during daily routines, like simple speech activities during play or mealtime, tend to see steadier gains between sessions.
Why early intervention helps: evidence and professional guidance
ASHA's updated developmental milestones point to birth through age 3 as the window when intervention tends to have the strongest effect, though speech therapy can still help children well past that age. IDEA Part C backs this up with legal timelines built specifically for infants and toddlers, pushing families from referral to services in a matter of weeks rather than months. The rationale is rooted in how quickly young children's brains build the foundations for later literacy and social connection. None of this means overnight results: timing still comes down to clinical judgment and what matters most to your family, not a single number on a calendar.
Thriving Joy's family-centered view on timing
We look at timing the way ASHA recommends: through clinical judgment paired with what your family actually needs day to day. Before recommending a starting point, we ask about mealtime struggles, safety concerns, and what communication looks like at home. Bringing milestone notes, short videos, and your own observations to that first conversation helps us build a plan around your child's real life, not a generic checklist.

If you want professional help now: Thriving Joy services and how to get started
Thriving Joy Pediatric Therapy offers early intervention-focused speech therapy alongside feeding therapy and parent coaching, so families dealing with overlapping concerns, like a toddler who both struggles to talk and has trouble at mealtimes, don't have to coordinate multiple unconnected providers on their own. Intake typically starts with a conversation about your child's history and your goals, followed by an evaluation that we can coordinate directly with your pediatrician or early intervention team. If a tongue or lip tie is part of the picture, we can also point you toward resources like Integrative Dental of Denver's guidance on ties in children as part of a fuller picture of care. Reach out through our speech therapy page to schedule an evaluation and take the next step toward clearer communication for your child.

FAQ
What are the first signs of speech delay?
Early signs include limited babbling in infancy, few or no gestures like pointing or waving by 12 to 18 months, and fewer words than expected by 18 to 24 months. Losing a skill your child previously had, sometimes called regression, is also an early and important signal worth mentioning to your pediatrician.
Should a 2 year old go to speech therapy?
A 2 year old should be evaluated if they are combining very few or no words, are hard to understand even for familiar listeners, or are missing several milestones at once. ASHA recommends letting clinical judgment and parent concerns guide the decision rather than waiting to see if a child catches up on their own.
Is it normal for a 2.5 year old to not talk?
It's not typical for a child this age to have no words or very few words, and this pattern warrants a developmental screening rather than a wait-and-see approach. Requesting an evaluation early allows your family to start early intervention services sooner if they're recommended.
Is 4 too late for speech therapy?
No, speech therapy can help children well beyond the toddler years, even though ASHA notes that intervention tends to be most effective between birth and age 3. A 4 year old with speech or language concerns can still make meaningful progress with the right evaluation and therapy plan.
