If you’ve noticed your child isn’t talking as much as other kids their age, or if your pediatrician has mentioned “speech delay” or “language delay,” you might be wondering what those terms actually mean, and whether there’s a difference.

There is. And understanding it helps you ask the right questions and get your child the right kind of support.

Speech vs. Language: The Basic Distinction

Speech and language are related but different things.

Speech is the physical act of producing sounds, how clearly and accurately your child says words. When a child has a speech delay or speech sound disorder, they may have trouble forming sounds correctly, leave out sounds, or be difficult to understand even when they’re saying lots of words.

Language is about meaning, understanding and using words, sentences, and concepts to communicate. A child with a language delay may have trouble understanding what you say to them (receptive language), or trouble expressing their own thoughts and ideas in words (expressive language), or both.

A child can have a speech issue without a language issue, a language issue without a speech issue, or both at the same time. They often overlap, but they don’t have to.

What a Speech Delay Looks Like

A child with a speech delay is working on the mechanics of talking, the sounds and the clarity. Some things parents notice include being hard to understand even for family members who are used to them, leaving out sounds at the beginning or end of words (“at” for “cat,” “cu” for “cup”), substituting sounds in predictable ways that persist past typical developmental ages, and avoiding words that are hard to say.

It’s worth knowing that some sound errors are completely normal at certain ages. A three-year-old saying “wabbit” for “rabbit” is on track. A five-year-old still doing that is worth a look. Speech-language pathologists use developmental norms to evaluate which errors are expected and which suggest a child needs support.

What a Language Delay Looks Like

Language delays are often a little harder for parents to put their finger on, because they involve not just what a child says but how they understand and use communication.

On the receptive side, understanding, a child might not respond to their name consistently, have trouble following simple instructions like “get your shoes” or “give it to me,” seem confused by questions, or need directions repeated frequently.

On the expressive side, talking, a child might have a smaller vocabulary than expected for their age, use sentences that are shorter or simpler than their peers, have trouble retelling what happened at school or in a story, or rely on a lot of gestures instead of words.

A child can be a clear speaker, easy to understand, but still have a language delay if their vocabulary is limited or they’re struggling to put thoughts into full sentences.

What About Late Talkers?

“Late talker” is a term used informally for toddlers, usually 18 to 30 months, who have fewer words than expected for their age but don’t show other signs of developmental concern. Many late talkers do catch up on their own. But research shows that late talkers who also have limited play skills, limited understanding, or a family history of language difficulties are at higher risk of continuing to lag.

The challenge with waiting to see if a child catches up is that early intervention produces better outcomes than later intervention. If there’s a concern, a speech-language evaluation is always the right first step. It either gives you reassurance or gets your child support sooner. There’s no downside to knowing.

What a Speech-Language Evaluation Involves

An evaluation with a Wee Care speech-language pathologist typically takes 60 to 90 minutes. The SLP will observe your child in play, interact with them directly, and gather information from you about their development, how they communicate at home, and what you’ve noticed.

The evaluation looks at both speech and language. It’s not one or the other. If your child has concerns in both areas, both get assessed.

At the end, you’ll have a clear picture of where your child is relative to developmental expectations, whether they qualify for therapy, and if so, what kind of support would help most.

Wee Care provides speech therapy for children in Savannah, Bloomingdale, Richmond Hill, Pooler, Rincon, and Garden City, in-home, at daycares, and at our clinics. If you’re not sure whether your child’s communication is typical or something to look into, that’s exactly the kind of question a phone call can help answer.

Frequently Asked Questions

How do I know if my child has a speech delay or a language delay?

An evaluation with a speech-language pathologist is the only reliable way to know. Speech delays involve how clearly sounds are produced; language delays involve understanding and using words and sentences. Many children have both. A brief phone consultation with Wee Care can help you decide whether a full evaluation is the right next step.

My child is 2 and only says about 20 words. Is that a delay?

Typical 2-year-olds generally have around 50 words and are starting to put two words together (“more milk,” “go bye-bye”). Twenty words at age 2 is below typical range and worth discussing with a speech-language pathologist. Early support, when indicated, makes a meaningful difference.

Should I wait to see if my child catches up on their own?

Some children do catch up, but research supports early intervention for children who are behind. An evaluation tells you whether watchful waiting is appropriate or whether earlier support would help. The evaluation itself doesn’t commit you to anything.

Does Wee Care offer speech therapy and language therapy?

Yes. Our speech-language pathologists address both speech sound production and language development. The evaluation identifies what your child needs, and therapy is tailored from there.

Can siblings or other family members be part of the evaluation?

Family input is always part of the process. You know your child best, and your observations about what you’re seeing at home are a valuable part of the picture.
