Speech & Language Milestones (18–24 Months): A Parent Playbook 🌱
Speech milestones at 18 to 24 months
First words, little phrases, and plenty of questions. Here is how to understand your toddler’s communication, encourage it during everyday routines, and know when to ask for support.
What should an 18 to 24 month old be saying?
CDC lists attempts at three or more words beyond “mama” and “dada” by 18 months, and two words together by age 2. Understanding, gestures, and hearing matter too. If your child misses a milestone, loses a skill, or you have concerns, speak with their pediatrician rather than waiting for several signs.

18 month and 24 month speech milestones
It helps to separate what is expected at 18 months from the skills developing closer to a second birthday. CDC provides age-specific developmental checkpoints. ASHA’s guidance describes communication across the 19 to 24 month range.
| Age / source | Skills to look for |
|---|---|
|
By 18 months CDC |
|
|
19 to 24 months ASHA |
|
|
By 24 months CDC |
|
These frameworks serve different purposes. ASHA’s 50-word guidance covers an age range; it is not an 18-month requirement. Neither a vocabulary count nor a milestone checklist diagnoses a disorder.
Look beyond the number of words
Speech is how a child produces sounds. Language includes understanding messages and expressing ideas. A toddler may need support with one or both, so an evaluation looks beyond pronunciation.
Bring examples of how your child asks for help, responds to familiar requests, and joins everyday interactions. You do not need a perfect word list before making an appointment.

When should you ask about a speech delay?
Discuss a missed milestone or any communication concern with your child’s pediatrician. You do not need to wait until age 2 or see several difficulties at once.
If your child stops using words, gestures, or another skill they previously had, contact their pediatrician promptly and describe the change.
Other concerns to discuss include:
- Limited pointing or other gestures used to communicate.
- Difficulty understanding familiar words or requests.
- Little progress in learning new words.
- Difficulty putting words together as the second birthday approaches.
- Inconsistent responses to sound or concerns about hearing.
Ask about developmental screening, a speech-language evaluation, and hearing testing. Families can also contact their state’s early intervention program for children younger than 3 to ask about eligibility and an evaluation.

Six speech and language activities for toddlers
Try an idea during play, dressing, or story time. These are opportunities to connect, not tests your child needs to pass.
-
Talk about what is happening
Use short comments during routines instead of asking a question every time.
At the sink: “Water on. Wash hands.”
-
Offer a simple choice
Show two options and leave time for a response. Acknowledge gestures as well as words.
During play: “Blocks or train?”
-
Add a little to their words
Build on what your child says with a short phrase.
Child: “Hat.” Adult: “Your hat!”
-
Share a picture book
Follow the pictures that interest your child. Name them, pause, and respond to their attempts.
“A duck. Duck is swimming.”
-
Play with sounds
Use playful sounds with toys or songs, leaving room for your child to join in.
A toy bus goes “beep!”
-
Take turns with gestures
Wave, clap, or copy a playful movement together. Pair the action with a word.
Wave and say “Hello!”
Home practice can complement professional guidance. Continue with an evaluation when there are concerns, even while trying these activities.

What if your child is learning two languages?
Learning more than one language does not cause a speech or language disorder. Keep using the languages you are comfortable speaking with your child. Tell the evaluating SLP which languages your child hears and uses so the assessment can consider their full language experience.

A speech and hearing evaluation can clarify next steps
An SLP asks about development and how your child communicates. The assessment may include play, observation, and structured tasks to explore understanding, expression, and speech sounds.
Hearing testing is often part of the process because hearing difficulties can affect communication. Findings help guide recommendations, which may include home strategies, therapy, or further assessment.
A few notes about what you notice, your questions, and any prior hearing or developmental results can help you explain your concerns.

Toddler speech milestones, answered clearly
My 18 month old is not talking. Should I wait?
Ask your pediatrician about developmental screening and speech and hearing evaluations now. CDC’s 18-month checkpoint includes trying three or more words beyond names for parents. Your concern is enough to start the conversation.
How many words should a 2 year old say?
ASHA’s 19 to 24 month guidance includes understanding and using at least 50 words. CDC’s 2-year checklist includes combining two words. These are different frameworks, not standalone diagnostic cutoffs.
My 2 year old uses single words but no phrases. What next?
Discuss this with your pediatrician and an SLP. Combining words is a CDC 2-year milestone. You do not need additional concerns before asking for an assessment.
Why is a hearing test recommended for a speech concern?
Hearing difficulties can affect speech and language development. NIDCD notes that hearing testing is often included in an evaluation to help identify what may be contributing to the concern.
Should we stop speaking our home language?
No. Keep using the languages you are comfortable speaking. Share your child’s language background with the SLP so it is considered during assessment.
Can we try activities while waiting for an appointment?
Yes. Read, play, and respond to your child’s communication during familiar routines. Keep the appointment so a professional can address your concerns and tailor recommendations.
