Speech and Language Development in Early Childhood
Speech-language therapy supports how children understand language, express themselves, produce speech sounds and use communication socially. It is provided by a speech-language pathologist (SLP), and early support is often recommended because communication underpins learning, relationships and behavior.

Speech vs language: an important difference
Speech
The physical production of sounds: articulation, fluency (stuttering) and voice.
Receptive language
Understanding words, directions, questions and stories.
Expressive language
Using words and sentences to share needs, ideas and experiences.
Pragmatic (social) language
Taking turns, staying on topic, reading tone and adjusting to listeners.
A child can have clear speech but a language delay, or a rich vocabulary that is hard to understand. An SLP evaluates each area separately.
Common reasons children see an SLP
- Late talking — fewer words or word combinations than expected for age
- Speech sound disorders — persistent errors such as substituting or leaving out sounds beyond the expected age
- Childhood apraxia of speech — difficulty planning the movements needed for speech
- Language disorders — difficulty understanding or using language, including developmental language disorder
- Stuttering — repetitions, prolongations or blocks that affect communication
- Social communication differences, often but not only in autistic children
- Feeding and swallowing concerns, which some SLPs specialize in

Augmentative and alternative communication (AAC)
AAC includes anything that supplements or replaces speech: signs, picture boards, and speech-generating devices or apps. Research and professional guidance do not support the worry that AAC stops children from learning to talk; it gives children a way to communicate now, and many continue developing speech alongside it.
Good AAC use involves adults modeling the system throughout the day, not just during therapy.
How to get a speech-language evaluation
| Age | Route |
|---|---|
| Under 3 | Contact your state's Early Intervention program directly — a doctor's referral is not required |
| 3 to 21 | Request a free evaluation from your public school district in writing; see our <a href="/iep-504-guide">IEP vs 504 guide</a> |
| Any age | Private evaluation through an SLP clinic or hospital; check insurance coverage first |
SLPs in the US are licensed by their state, and many hold the Certificate of Clinical Competence (CCC-SLP) from the American Speech-Language-Hearing Association (ASHA).
Supporting communication at home
- Get face-to-face and follow your child's interest during play
- Narrate what you and your child are doing in short, simple phrases
- Expand on what your child says: if they say "car," you might say "blue car!"
- Pause and wait — give time to respond before filling the silence
- Read together daily, pointing to pictures and asking open questions
Frequently asked questions
Should I wait to see if my child catches up?
If you are concerned, it is reasonable to ask for an evaluation rather than wait. Early Intervention evaluations are free, and an evaluation can rule concerns in or out.
Does bilingualism cause speech delays?
No. Children learning two or more languages follow similar overall milestones. An evaluation should consider all of a child's languages.
