TL;DR
A communication log is a written or digital record of what your child says, how often, and in what situations. Kept a few times a week, it gives your speech-language pathologist real data between sessions, speeds up goal adjustments, and helps you catch patterns you'd otherwise forget. Ten minutes a day is plenty.
What is a communication log and why do SLPs ask for one?
A communication log is a running record of your child's communication attempts. New words. New sounds. Gestures, requests, meltdowns that seem tied to not being understood, moments of surprise clarity at the dinner table. You write them down, date them, and hand them to your therapist.
Speech-language pathologists (SLPs) see your child for 30 to 60 minutes, once or twice a week in most outpatient clinics. That's roughly two hours a month out of the 720 hours your child is awake. The log fills in the other 718. Without it, your SLP is reading your child from a tiny sample. [1]
The American Speech-Language-Hearing Association treats parent and caregiver input as a core part of evidence-based practice in pediatric speech-language pathology. [1] That's more than a courtesy. Therapy goals that aren't calibrated to what's actually happening at home tend to drift. A log keeps them anchored.
You don't need an app or a clipboard. A notes app works. A spiral notebook works. The format matters far less than the habit.
What should I actually write in a communication log?
This is where most parents freeze. They either try to document everything, quit by day three, or write so little the entries tell nobody anything. Here's what SLPs actually want, sorted into categories.
New or emerging words and sounds. The first time your child says "more" unprompted is worth noting. So is a new consonant that showed up at breakfast. Write the exact word or approximation, not a paraphrase. If your child said "wawa" for water, write "wawa," not "asked for water."
Spontaneous versus prompted. Did they say it on their own, or did you model it first? This distinction drives goal tracking. Write "spontaneous" or "after model" in a short note next to the entry.
Context. Where were you? What was happening? Communication often ties to routine, sensory state, or a specific person. A child who only says a word during bath time is telling you something real about when language feels safe or worth the effort. [2]
Attempts that didn't work. Frustrated reaching, pointing, vocalizing without words, crying at a transition. These breakdowns are data, not failures. Note them.
AAC use if applicable. If your child uses a device or a low-tech board, log which symbols they hit, and whether independently or with prompting. See also: [aac devices] [3]
What you tried and what happened. Did you expand their utterance? Offer a choice? Did a strategy fall flat today? That feedback loop is gold for your SLP.
Skip the words your child has already mastered. Focus on the edges: things that are new, things that are inconsistent, and things that are absent but expected.
How often should I update the log?
Daily is ideal but rarely realistic. Three or four times a week is genuinely enough, as long as you're catching meaningful moments instead of chasing completeness.
The biggest mistake is batch-writing from memory the night before a session. Human memory for specific utterances fades fast. In a well-known Psychological Science study on event memory, Roediger and Karpicke found that details about when and how something happened drop off sharply within 24 to 48 hours. [4] Write entries within a few hours of the moment, even if it's just a quick line you flesh out later.
Here's a system many parents settle into. Keep your phone's notes app open to a running "speech log" document. Tap in a quick entry when it happens, even three words: "said ball, spontaneous, outside." Then once a week, before the session, spend five minutes reading back and adding any context you remember.
If you have a co-parent or other caregivers, pick one person to own the log. Two people writing in the same document with different systems creates a mess. Better to use a shared notes app where others can drop quick observations, and have one person clean up and standardize the entries before the session.
What does a good log entry actually look like?
Here's the gap between a vague entry and a useful one.
Vague: "She talked a lot today."
Useful: "Said 'more' spontaneously three times during snack (goldfish crackers). No prompt from me. Clear, full /m/ sound. Tried again at dinner but it came out as 'muh' only."
The useful entry has a date (implied), a specific word, a count, the context, whether it was prompted, and a note about variability. Your SLP can do something with that. She can't do much with "talked a lot."
You don't have to write full sentences. Bullet points are fine. Shorthand is fine. If you can read it back in a week and reconstruct what actually happened, the format is working.
| Entry element | Why it matters |
|---|---|
| Exact word or sound | Lets the SLP track articulation, not only vocabulary |
| Spontaneous vs. prompted | The core metric for most therapy goals |
| Context (place, activity, who was present) | Identifies what helps and what gets in the way |
| Time of day | Fatigue, hunger, and sensory load shift by the hour |
| Communication breakdowns | Shows where frustration is building |
| Your response | Lets the SLP coach your in-the-moment strategy |
How does a communication log help therapy goals get adjusted?
Speech therapy goals are written in measurable terms: something like "child will produce the target word spontaneously in 4 out of 5 opportunities across two settings." [1] The only way to know if a child is hitting that benchmark outside the clinic is data from home.
Bring a log showing your child has used a target word spontaneously all week, and your SLP can push the goal forward instead of drilling something your child already owns. The reverse matters just as much. If a word your child produces perfectly in the therapy room has never once appeared at home, that's a generalization problem, and your SLP needs to know so she can go after it directly. [2]
The log also saves you from the session check-in trap. Without notes, most parents either say "she's doing great" off yesterday's good day or "nothing is working" off this morning's rough hour. Neither is accurate. The log gives both of you something to read instead of leaning on mood-colored recall.
For children on the autism spectrum, where communication can be heavily context-dependent and may include echolalia or scripted language, the log matters even more. What shows up in a structured therapy room can look nothing like what happens at home. [5] See also: [autism spectrum speech therapy]
What format should I use: paper, app, or spreadsheet?
There's no single right answer. The best format is the one you'll actually keep up. Here are the honest trade-offs.
Paper notebook. Almost no friction to start. No battery, no crashes. Easy to hand to your SLP in the waiting room. But it's hard to search, easy to lose, and your handwriting turns to scrawl when you're jotting at a playground.
Phone notes app (Apple Notes, Google Keep, Notion). Most parents already have one open. Fast to capture in the moment. Searchable. Easy to screenshot or share a link with your SLP. The catch is that one long unstructured note gets hard to skim.
Spreadsheet (Google Sheets). Best for parents who like structure. Set up columns for date, time, word or utterance, spontaneous or prompted, context, and notes. Sort by date or category. Mildly annoying to fill in on a phone keyboard.
Dedicated speech apps. A few exist, quality varies, and most cost money. Little Words, for example, is an AI speech companion that tracks communication patterns over time and surfaces trends for your SLP to review. Worth a look if you want more structure than a notes app but less friction than a spreadsheet. See also: [online speech therapy]
SLP-provided forms. Many clinics hand you a log template at intake. Use it. Your therapist built it around what she needs, and returning it completed makes the working relationship better.
If you're just starting, open your phone's notes app right now and make a document called "Speech Log [Child's name]." You can migrate to a fancier system later. Starting beats optimizing.
How do I share the log with my child's speech therapist?
Ask. At the next session, find out how your SLP prefers to get it. Some want to review it in the room. Others want a summary email the night before so they can adjust the plan. A few will glance at it in the waiting room. Don't guess, ask.
If you're emailing or texting, keep it short. A bullet summary of the week's highlights beats a wall of text. Something like:
- Mon: "more" spontaneous x3 at snack
- Wed: Major breakdown leaving the park, no words, just crying and reaching
- Thu: Used "help" unprompted when a toy was out of reach (first time!)
- Fri: Tried to imitate "ball," stopped at "buh"
Four days of data in five lines. Your SLP can work with that in 30 seconds.
If your child gets early intervention services under IDEA Part C (children under age 3), the log also supports the Individualized Family Service Plan (IFSP) process. [6] Documented home communication patterns count as evidence when the team is writing or revising goals. Keep copies.
For school-age children under IDEA Part B, the log supports IEP goal reviews. [6] Parent-reported data is explicitly allowed as one source of progress evidence.
What if my child uses gestures or AAC instead of words?
Log those exactly the same way. Gestures, pointing, eye gaze toward a symbol, reaching, a head-shake for no, all of it is real communication. The American Academy of Pediatrics and ASHA both recognize that communication is wider than spoken words, and that augmentative and alternative communication (AAC) supports language development rather than replacing it. [3] [7]
For gesture-based communication, note the gesture, its apparent meaning, and whether an unfamiliar listener would have caught it. For AAC, note which symbols were accessed, in what sequence, and whether the message landed. If your child is using childhood apraxia of speech strategies alongside AAC, the log matters even more, because the motor-planning patterns can be highly session-specific and may not transfer right away. [8]
One thing to watch. If your child's main communication is echolalia, functional or not, log the phrases anyway. Note whether the echo seemed communicative (requesting, protesting, commenting) or looked non-communicative (sensory, self-regulatory). See also: [echolalia meaning] Your SLP can help you read the patterns, but she needs the raw data first.
How long should I keep the log going?
Keep it as long as your child is in therapy, and honestly a bit past. Speech progress is rarely a straight line. [2] A log that spans six months lets you look back and see growth that's invisible week to week.
When your child moves between providers, or from early intervention to school-based services, the log is one of the most useful things you can hand over. A new SLP reading six months of home observations calibrates goals far faster than one starting cold.
If therapy ends and you're watching for regression or readiness for re-referral, even a monthly entry earns its keep. The log doesn't have to stay intensive forever. But a time-stamped record of where your child stood at age 3, age 4, and age 5 is genuinely valuable if questions come up later.
Parents sometimes ask whether logs can be used in evaluations. They can. Documented parent report is a standard data source in standardized speech-language evaluations. ASHA's practice guidance for child language disorders lists caregiver report as one of the primary information sources alongside standardized testing, observation, and dynamic assessment. [1]
What are the most common mistakes parents make with communication logs?
Writing too rarely, then guessing. Filling in a week from memory the night before a session is close to useless. Write in the moment or within a few hours.
Only logging wins. It's natural to want to report the good stuff, but breakdowns and regressions carry just as much weight. A week where your child seemed to lose a word they'd had for a month is important clinical information.
Being too vague. "She communicated well" tells your SLP nothing. Specific words, specific contexts, specific counts.
Stopping during good stretches. When things are going well, it's tempting to skip the log. But the good stretches are exactly when you want data, because they show your SLP what conditions support progress.
Logging your interpretation instead of the behavior. "She was frustrated" is an interpretation. "She cried, threw her cup, and reached toward the shelf where her tablet lives" is a behavior. Describe what you saw and heard before you explain what you think it meant.
Comparing to siblings or other kids. The log is a record of your child's own trajectory, not a scoreboard. Skip entries like "still not doing what her brother did at this age." Those thoughts belong in a conversation with your SLP, not in the data.
Can a communication log help me notice signs that therapy isn't working?
Yes, and this is one of the log's most underrated uses. If you've been in therapy three or four months and the log shows no new words, no new contexts, and no drop in breakdown frequency, raise it directly with your SLP.
Progress benchmarks vary by child, diagnosis, and starting point, so no single number signals a problem. But ASHA guidance on service delivery says progress should be monitored regularly, and that lack of progress should trigger a reassessment of goals, approach, or frequency. [11]
A log showing flat or declining data gives you something concrete to bring to that conversation instead of a vague feeling. It also protects you from waving off a genuine plateau as "just a bad week" when it's actually a six-week pattern.
If you're worried your child isn't progressing and you want a second opinion, the log is exactly what a new evaluating SLP will want to see. Bring it. See also: [speech therapy speech therapist]
For parents using Little Words, the app's longitudinal tracking can surface these patterns automatically, so you can spot a plateau without hand-tallying weeks of entries. Useful when you're tired and busy, which is most of the time.
Is there research supporting communication logs as a therapy tool?
Direct studies on communication logs as a standalone intervention are thin. Nobody has run a randomized trial on "log vs. no log." Most of the supporting evidence comes from the broader literature on parent-implemented language intervention, where active parental observation and recording sits inside effective programs.
The Hanen Centre's "It Takes Two to Talk" program, which has a reasonable evidence base for late talkers, includes parent observation and self-monitoring as core components. [9] Research on parent-implemented naturalistic developmental behavioral interventions (NDBIs) for autistic children consistently finds that parent engagement in tracking and responding to communication attempts improves outcomes. [10]
ASHA's practice guidance on child language disorders treats caregiver report and observation as essential sources of information in both assessment and progress monitoring. [1] That's about as close to an official endorsement as you'll get for a practice that's more clinical common sense than tested intervention.
The closest evidence is this. When parents are trained to observe and record communication, their responsiveness to their child's attempts improves, and that responsiveness is itself linked to better language outcomes. [2] The log, in other words, may help your child partly by sharpening your attention.
Frequently asked questions
What should I include in a communication log for a 2-year-old?
For a 2-year-old, focus on new words or word approximations, whether they were spontaneous or prompted, gestures like pointing or reaching, and communication breakdowns. Note the context: mealtime, play, bath. At this age, the number of different words (vocabulary size) and whether the child combines two words are key data points for your SLP. The AAP's 24-month benchmark is around 50 words and emerging two-word phrases. [7]
How detailed does a communication log need to be?
Detailed enough to reconstruct what happened, not so detailed you burn out. A date, the specific word or gesture, whether it was spontaneous or prompted, and a one-line context note is genuinely enough. Four or five fields per entry is the practical ceiling. If an entry takes more than two minutes, you'll stop, and an imperfect log kept for months beats a perfect one abandoned in week two.
Can I use a Google Sheet as a communication log template?
Yes, and it works well. Set up columns for date, time, word or utterance (exact), spontaneous or prompted, context (where, who, activity), and notes. Google Sheets syncs across devices, shares with your SLP via link, and sorts or filters by date. If you want a starting template, copy those six column headers and fill in one row from memory as a practice run right now.
How do I log communication if my child doesn't use words yet?
Log every intentional communication act: reaching toward something, pointing, bringing you an object, vocalizing while making eye contact, using a facial expression to respond. Note whether the act was aimed at a person (communicative) or looked self-directed. For AAC users, log each symbol access. Pre-verbal and non-verbal communication is rich data, and your SLP needs it to place where your child sits in the communication development sequence.
Should I show the log to teachers or daycare workers?
Yes, if your child's communication goals reach into those settings, which they usually should. Sharing the log, or at least a summary, helps teachers watch for the same behaviors and report back. For children with IEPs or IFSPs, communication between the SLP, family, and school team is explicitly supported under IDEA. [6] A shared notes doc or a short weekly email to the teacher extends the log into the classroom without much extra work.
What if I miss a day or a whole week of logging?
Pick it back up without drama. A gap is not a crisis. Write what you can remember, note that those entries are from memory rather than real time, and move on. The real mistake is letting guilt about a missed week turn into abandoning the log. Partial data over three months is far more useful to your SLP than perfect data for two weeks.
How do I use a communication log to prepare for an IEP meeting?
Read back through the log for the past two to three months and make a one-page summary: total new words or phrases since the last meeting, contexts where communication is strongest, patterns of breakdown, and any strategies that seem to help or hurt. Bring the original log as backup. Parent-reported progress data is a recognized input to IEP goal-setting under IDEA Part B. [6] A concrete summary carries more weight than impressions.
Can a communication log help with an autism diagnosis or re-evaluation?
It can support the process, though it's not a diagnostic tool. Evaluating psychologists and SLPs often ask for developmental history and current communication patterns. A dated log gives them real observations instead of reconstructed memory. For autism evaluations in particular, context-dependent patterns, like words that appear only in certain settings or with certain people, are clinically relevant and hard to capture without a running record. [5]
How is a communication log different from a speech therapy homework sheet?
Homework sheets from your SLP are structured practice activities, like drilling a specific sound or rehearsing a scripted phrase. A communication log is an observational record of naturally occurring communication across the day. Both matter. The homework sheet targets a skill in a controlled context; the log tells you whether that skill is generalizing into real life. They're complementary, not interchangeable.
What if my SLP doesn't ask for a communication log?
Keep one anyway and offer to share it. Not every SLP asks, but very few will turn down good home observation data. At your next session, try: "I've been keeping notes on what I'm seeing at home. Would it help if I shared them?" Most therapists say yes. If yours discourages parent input, treat that as a red flag about the collaborative fit.
How do I log echolalia in a communication log?
Write down the exact phrase echoed, where it came from if you know (a TV show, an earlier conversation), and whether it seemed to serve a communicative function. Functional echolalia, like repeating "do you want a snack?" to mean "yes I want a snack," is different from non-functional echoing. Your SLP needs both, but the distinction helps her plan. [See also: echolalia meaning for more on how echolalia fits into communication development.]
How long does it take to keep a communication log each day?
Five to ten minutes if you write close to real time. More if you batch them. The fastest system is a running phone note: 15 to 30 seconds per entry in the moment, then a five-minute weekly review before the session. The time cost is small next to the payoff in better-targeted therapy. Think of it as the homework that makes the 30-minute session worth far more.
At what age should I start keeping a communication log?
As soon as you have concerns about your child's communication, whatever their age. If your child is under 3, you may already be in or pursuing early intervention, and the log helps that team immediately. [See also: early intervention for timelines and eligibility.] There's no minimum age. A log started at 18 months with a late talker gives you a developmental timeline that pays off for years.
