Signs of Speech Delay: When to Get an Evaluation

Written and reviewed by Nita Anavim, M.S., CCC-SLP. Last reviewed August 18, 2026.

You have been going round this for weeks. Some days you are certain something is off. Other days he says a new word and you decide you are overthinking it. Your mother says wait, the internet says act now, and the pediatrician said let’s see at the next visit. If you are trying to work out whether it is time for a speech evaluation, what you probably need is not more reassurance. It is a clear list.

A speech evaluation is an assessment by a licensed speech-language pathologist that compares your child’s communication against what is typical for his age and tells you whether there is a gap worth addressing. It is not a commitment to therapy, and a normal result is a perfectly good outcome.

What are the red flags at each age?

Some signs matter more than others. By 12 months, no babbling, no pointing or waving, and no response to his name. By 18 months, fewer than a handful of words, no attempt to copy you, and not following a simple direction without gestures. By two, not putting two words together, and a vocabulary that has stalled rather than growing. By three, speech that strangers cannot understand most of the time, or still speaking mainly in single words.

By four, ongoing difficulty being understood, trouble telling you a simple thing that happened, or a struggle to answer basic questions. At any age: losing words or skills he previously had, obvious frustration when trying to communicate, or a persistent gut feeling that something is different. Our speech milestones by age guide has the fuller picture.

What is not a red flag?

Worth saying, because a lot of parents lose sleep over things that are ordinary. Mispronouncing harder sounds like r, s, th and l well into the early school years is normal, and those sounds are among the last to settle. A brief patch of stumbling and repeating words in a two- or three-year-old is extremely common and usually passes.

Being quieter than a chatty cousin is not a delay. Growing up bilingual does not cause language delay, and the total across both languages is what counts. And a child who understands everything but says little is showing you a specific pattern rather than a global problem, though that one is still worth checking.

What if I’m the only one who notices?

Being the only one who notices is common, and it is reason enough to ask. Parents spend more hours with their child than anyone and are often right that something is different, well before it shows up in a fifteen-minute appointment.

“Let’s wait and see” is reasonable advice in some situations and a costly default in others. If you have been told to wait and the waiting is not sitting right, you are allowed to ask for an evaluation anyway. You do not need anyone’s permission to get information about your own child.

What actually happens at an evaluation?

An evaluation is largely play and conversation, less clinical than most parents expect. It is largely play and conversation, with the therapist watching how your child communicates, testing understanding and expression, listening to speech sounds, and asking you a lot of questions, because your account of a normal day matters as much as anything measured in the session.

You come away with a plain-language picture: what is typical, what is behind, and what would help. Our post on what to expect at a speech evaluation walks through it step by step.

What if we are wrong and he is fine?

Then you get told he is fine, usually with a few things to do at home, and you stop lying awake. That is a genuinely good result, not a wasted appointment.

The asymmetry is the whole argument. Checking unnecessarily costs an hour and some awkwardness. Waiting when you should not have costs the years when language develops fastest and support works best. Nobody can tell you in advance which late talkers will get there on their own, which is exactly why waiting is a gamble rather than a plan. Our post on telling a late talker from a speech delay covers how that judgment gets made.

One practical step first: get hearing checked. Even mild or intermittent hearing loss slows language quietly and is easy to miss, and it changes what an evaluation means.

If you want to talk it through before committing to anything, that is what a consultation is for. Our in-home speech therapy starts with a conversation rather than a form.
