Signs Your Child May Need Speech Therapy

Every child develops at their own pace, and there is natural variation in when children reach speech and language milestones. But there are also clear signals that development may be outside the typical range — signals that warrant a conversation with a speech-language pathologist rather than a wait-and-see approach.

The earlier a speech or language delay is identified and addressed, the better the outcomes tend to be. Early intervention during the critical window of language development can make a profound difference in a child's communication, social development, and academic readiness.

Understanding the Difference Between Speech and Language

Before looking at specific signs, it helps to understand the distinction between speech and language — two terms that are often used interchangeably but mean different things.

Speech refers to the physical production of sounds — articulation, voice quality, and fluency. A child with a speech disorder may have difficulty producing certain sounds clearly, may stutter, or may have a voice that sounds unusual.

Language refers to the system of words, grammar, and meaning used to communicate. A child with a language disorder may have a limited vocabulary for their age, difficulty forming sentences, trouble understanding what others say, or challenges using language socially.

A child can have a speech difficulty without a language difficulty, a language difficulty without a speech difficulty, or both simultaneously.

Developmental Milestones to Know

Speech-language development follows a general sequence. The following are widely referenced benchmarks:

By 12 months: Babbling with varied sounds, using gestures like pointing and waving, responding to their name, saying one or two words like "mama" or "dada."

By 18 months: Using at least 10 words, pointing to familiar objects when named, following simple one-step directions.

By 24 months: Using at least 50 words, beginning to combine two words together ("more juice," "daddy go"), strangers can understand about half of what the child says.

By 3 years: Using sentences of three to four words, asking questions, strangers can understand about 75 percent of what the child says, following two-step instructions.

By 4 years: Speaking in sentences, telling simple stories, nearly all speech understandable to strangers, using most sounds correctly except a few like "r" and "th."

By 5 years: Using well-formed sentences, telling detailed stories with beginning, middle, and end, using most speech sounds correctly.

Specific Signs That Warrant Evaluation

Beyond general milestones, certain specific signs should prompt a referral for evaluation regardless of age:

No babbling by 12 months. Babbling is an early precursor to speech. Absence of babbling by 12 months is a red flag.

No words by 16 months. A child who has not said a single recognizable word by 16 months should be evaluated.

No two-word phrases by 24 months. Combining words is a significant developmental step. Absence by age two warrants attention.

Loss of previously acquired skills. Any regression — losing words or communication skills a child previously had — should be evaluated immediately. This can be associated with autism spectrum disorder and other conditions.

Significant difficulty being understood. If parents, caregivers, or familiar people consistently struggle to understand a child well beyond the typical period, evaluation is appropriate.

Stuttering that persists beyond six months or worsens. Many children go through a brief period of dysfluency around ages two to five. Stuttering that persists, is accompanied by physical tension, or is causing the child distress warrants evaluation.

Difficulty following directions or understanding language. Receptive language — the ability to understand what others say — is as important as expressive language. A child who frequently seems confused by instructions may have a receptive language difficulty.

Social communication difficulties. Difficulty making eye contact, not responding to their name, not engaging in back-and-forth communication, or not using language for social purposes can indicate a social communication disorder.

Voice that sounds consistently hoarse, breathy, or strained. Persistent voice changes in a child are worth investigating.

What Happens at an Evaluation

A speech-language pathologist will conduct standardized assessments appropriate for the child's age, observe the child in structured and unstructured activities, take a detailed developmental history, and may consult with other professionals if needed. The evaluation results in a clear picture of the child's strengths and areas of difficulty, and forms the basis for any recommended treatment.

When in Doubt, Get Evaluated

If you are uncertain whether your child's development is on track, the right move is always to get an evaluation rather than wait. A speech-language pathologist can reassure you that development is within normal limits, or identify a concern early when intervention is most effective. There is no downside to checking.

Your pediatrician can provide a referral, or you can contact a speech-language pathologist directly for an evaluation.
