Hearing aids and cochlear implants help many Deaf and hard-of-hearing children access sound. Some children make strong progress with listening and spoken language. Others don't. That gap is often missed, minimized, or explained away until significant time has passed.

This page is about that second group. It is for parents who have a feeling something isn't right, parents whose concerns keep getting answered with "give it more time," and parents who want to know what progress should actually look like: at what ages, by what markers.

The earlier a mismatch is caught, the more options a family has. Waiting is a risk. The window for language acquisition does not stay open indefinitely.

When a child thrives with a hearing device, it's visible. Speech develops. Language grows. Progress is documented at therapy appointments and school meetings.

When a child doesn't thrive, the failure often isn't visible in the same way. The child is wearing their device. They're attending therapy. They're in school. Progress is happening. Just slowly. The explanation from providers is usually "early days" or "every child is different" or "let's reassess in six months."

This is sometimes true. Early days are genuinely variable. But "every child is different" can also cover a real problem long enough to matter. By the time a family stops waiting and starts pushing, months or years of the critical language window may have passed.

The issue is not that devices fail children outright. The issue is that when a device-based approach is not working for a specific child, families are rarely given clear language that says so, a timeline for when to be concerned, or a plan for what comes next.

Not every child is equally at risk of a missed lag. Children who are more likely to face a gap that goes unnoticed include:

• Children identified or implanted later (after age 2, or after 12 months in the case of CIs)
• Children with additional disabilities alongside hearing loss
• Children from multilingual households where English is not the primary language at home
• Children whose hearing loss is progressive and was not caught at initial newborn screening
• Children in under-resourced therapy or school environments where progress is rarely benchmarked
• Children whose families were not clearly told what to expect or watch for

If your child fits one or more of these, monitoring is especially important. Not because progress is impossible, but because the standard assumptions embedded in many outcome studies may not apply to your child’s situation (for how cochlear-implant outcome studies define their enrolled populations, see Niparko et al., 2010, JAMA, 303(15), 1498–1506).

These are markers for children using hearing aids or cochlear implants who are pursuing a listening and spoken language approach. Missing one marker is not automatically a crisis. A consistent pattern of missing multiple markers over time (or missing the same marker at every check-in) is a signal to act, not wait.

By 12 months (device use): Consistent response to name and familiar sounds in a quiet room. Some vocalization that varies in pitch and pattern. Turning toward a speaker’s voice.

By 18 months (device use): A small set of meaningful spoken words (typically 10 or more for hearing children). Response to simple spoken directions without visual cues. Showing recognition of common environmental sounds.

By 24 months (device use): 50+ spoken words and beginning to combine two words. Understanding of simple two-step spoken directions. Clearly communicating wants and needs, even if not in full sentences.

By 36 months (device use): Sentences of three to four words. Strangers can understand much of what the child says. Child follows a conversation and responds to questions.

School age (5-6 years): Language at or close to age-level on standardized assessments. Child can follow classroom instruction without consistent individual repetition. Reading and phonological awareness developing on pace with hearing peers.

The spoken-language markers here follow general early-childhood communication milestones (see the American Speech-Language-Hearing Association’s developmental milestones), used here as a yardstick: a child using a hearing device is measured against the same spoken-language expectations, on a timeline that runs from when device use became consistent.

"Give it time" is reasonable advice in narrow circumstances: shortly after implant activation, when a device has been adjusted, when a family has just switched approaches. It is not a substitute for monitoring.

A useful rule of thumb: if you raise a concern about language progress and get "give it time" as the full answer, ask for a specific timeframe and a specific marker. "Give it until the six-month check-in, and by then we expect X" is usable. "Give it time" alone is not.

If a child has been using their device consistently for more than 12 months and is not meeting the benchmarks above, that is worth a formal evaluation, not just a therapy conversation. A full language assessment, not an informal clinical impression, is the appropriate response.

If a child has passed two or more check-in points with the same concern raised each time and no change in trajectory, a conversation about whether the current approach is meeting the child's language needs is warranted.

This is worth naming plainly. Audiologists, implant centers, and auditory therapy programs have professional and sometimes financial investment in the approach they have recommended. That does not make their concern for your child insincere. It does mean their threshold for "something isn't working" may be calibrated differently than yours.

Parents are not obligated to accept "let's see" indefinitely. You have the right to request a formal language assessment. You have the right to ask for a second opinion. You have the right to ask what the plan is if the current trajectory does not improve.

1. Request a formal language assessment, not just a therapy progress note. Ask for a standardized test that compares your child’s language to age-level norms. See Language Testing and What Language Assessment Results Mean for guidance on what this involves and what the scores mean.
2. Ask for your child’s language results in writing, so you can track progress over time and compare across evaluations.
3. Read up on language deprivation risk. If a gap is real and is not addressed, the consequences accumulate. See Language Deprivation: What It Is and Why It Happens and Understanding Language Deprivation Risk.
4. Ask specifically about communication approach options. The question is not whether to give up on devices (they often stay part of the picture), but whether your child needs access to a full visual language alongside or instead of spoken language. See Communication Approaches for a neutral overview.
5. If you have an IEP, bring your concerns to that meeting in writing before the meeting happens. See The Deaf Child IEP and Language Access Parent Guide for how to approach this.

This page focuses on device-outcome-specific warning signs for parents already pursuing a listening and spoken language approach. The Monitoring Language and Academic Progress page covers broader language monitoring for Deaf children across all approaches. The two are complements, not duplicates. If you haven’t read the monitoring page yet, it is a useful companion.

This page provides general information, not legal or medical advice. Verify your state’s specific rules and programs, and consult a qualified professional for guidance specific to your child.
