A communication log is nothing fancier than a running record of what your child says, tries to say, or attempts to communicate: new words, new sounds, a gesture, a meltdown that seems tied to not being understood, a burst of surprising clarity at the dinner table. You jot it down with a date and hand it to your therapist. Do this a few times a week and you'll give your speech-language pathologist real data between sessions, help goals get adjusted faster, and catch patterns you'd otherwise forget by next Tuesday. Ten minutes a day covers it. Most outpatient SLPs see your child for 30 to 60 minutes, once or twice a week, which works out to 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 working from a tiny sliver of who your child actually is. [1] The American Speech-Language-Hearing Association treats parent and caregiver input as a core part of evidence-based pediatric speech therapy, and that's not just politeness: goals that aren't calibrated to real life at home tend to drift, and a log keeps them anchored. [1] You don't need an app or a special notebook, either. A notes app on your phone works fine. The habit matters far more than the format.
What to actually write down
Most parents freeze at this step. They either try to document everything and quit by day three, or write so little the entries tell nobody anything. A few things are worth catching every single time. New or emerging words and sounds matter most: the first unprompted "more," a new consonant that showed up at breakfast. Write the exact word, not a paraphrase. If your child said "wawa" for water, write "wawa," not "asked for water." It also helps to note whether something was spontaneous or came after you modeled it first, since that distinction drives goal tracking directly. Context matters too: where you were, what was happening. Communication often ties to routine or a specific person, and a child who only says a word during bath time is telling you something real about when talking feels safe or worth the effort. [2] Don't skip the failed attempts either: frustrated reaching, pointing without words, crying at a transition. Those breakdowns are data, not failures.
If your child uses an AAC device or a low-tech board, log which symbols they hit and whether it was independent or prompted. [3] Note what you tried too: did you expand their sentence, offer a choice, did a strategy just fall flat that day? That feedback is genuinely useful to your SLP. Skip words your child has already mastered. Focus on the edges: what's new, what's inconsistent, what's absent but expected.
How often to write in it
Daily is ideal but rarely realistic. Three or four times a week is genuinely enough, as long as you're catching real moments instead of chasing completeness. The biggest mistake is batch-writing from memory the night before a session, because memory for specific details 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, even if it's just three words you flesh out later. A system that works for a lot of parents: keep a running "speech log" note open on your phone, tap in something quick when it happens ("said ball, spontaneous, outside"), then spend five minutes once a week before the session filling in context you remember. If there's a co-parent or other caregivers involved, pick one person to own the log. Two people writing in the same document with different systems turns into a mess; it works better to let others drop quick notes into a shared doc and have one person clean it up before the appointment.
Vague versus useful entries
There's a real gap between "She talked a lot today" and something like: "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 second one has a specific word, a count, the setting, whether it was prompted, and a note about how it varied. Your SLP can do something with that. She can't do much with "talked a lot." You don't need full sentences: bullet points and shorthand are fine, as long as you can read it back in a week and reconstruct what happened.
| 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 |
Why this changes how 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 your child is hitting that outside the clinic is data from home. Show up with a log proving your child has used a target word spontaneously all week, and your SLP can move the goal forward instead of drilling something already mastered. The reverse matters just as much: if a word your child nails in the therapy room has never once shown up at home, that's a generalization problem, and your SLP needs to know so she can address it directly. [2] The log also saves you from the check-in trap, where most parents either say "she's doing great" based on yesterday's good day or "nothing is working" based on this morning's rough hour. Neither is accurate. A log gives you both something to read instead of leaning on whatever mood you happened to be in that day. This matters even more for children on the autism spectrum, where communication is often heavily tied to context and may include echolalia or scripted language: what shows up in a structured therapy session can look nothing like what happens at home. [5]
Paper, app, or spreadsheet
There's no single right format, just the one you'll actually keep up. A paper notebook has almost no friction to start, doesn't crash, and is easy to hand your SLP in the waiting room, but it's hard to search and your handwriting turns to scrawl when you're jotting notes at a playground. A phone notes app like Apple Notes, Google Keep, or Notion is fast to capture in the moment, searchable, and easy to screenshot for your SLP, though one long unstructured note eventually gets hard to skim. A Google Sheet works well if you like structure: columns for date, time, word or utterance, spontaneous or prompted, context, and notes, sortable by date or category, though typing into it on a phone keyboard is mildly annoying. A few dedicated speech apps exist too, and quality varies, most cost money. Little Words, for instance, is an AI speech companion that tracks communication patterns over time and surfaces trends for your SLP: worth a look if you want more structure than a notes app but less hassle than a spreadsheet, and it pairs well with what you'd get from online speech therapy generally. Many clinics also hand you a log template at intake: use it, since your therapist built it around what she actually needs, and returning it filled out 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 move to something fancier later. Starting beats optimizing.
Sharing the log with your therapist
Just ask how your SLP wants to see it. Some like to review it together in the room. Others prefer a summary email the night before so they can adjust the plan ahead of time. A few are happy to glance at it in the waiting room. Don't guess, ask. If you're emailing or texting it over, keep it short. A bullet summary of the week's highlights beats a wall of text:
- 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"
That's four days of data in five lines, and your SLP can work with it in about 30 seconds. If your child gets early intervention services under IDEA Part C (children under age 3), the log also feeds into the Individualized Family Service Plan process. [6] Documented home communication patterns count as evidence when the team writes or revises goals, so keep copies. For school-age children under IDEA Part B, the same log supports IEP goal reviews, and parent-reported data is explicitly allowed as one source of progress evidence. [6]
What if my child uses gestures or AAC instead of words?
Log those exactly the same way you'd log words. 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 supports language development rather than replacing it.[3] [7]
For gesture-based communication, note the gesture, what it seemed to mean, and whether a stranger would have understood it. For AAC, note which symbols got accessed, in what order, and whether the message actually landed. If your child is working on childhood apraxia of speech strategies alongside AAC, the log matters even more, since motor-planning patterns can be highly session-specific and may not transfer right away.[8]
If your child's main communication is echolalia, functional or not, log the phrases anyway. Note whether the echo seemed to be doing something (requesting, protesting, commenting) or looked more automatic. Our guide to what echolalia means can help you sort through this, but your SLP needs the raw data first, before either of you can read the patterns.
How long should I keep the log going?
Keep it going as long as your child is in therapy, and honestly a bit past that. Speech progress rarely moves in a straight line,[2] and a log spanning six months lets you see growth that's invisible from one week to the next.
When your child changes providers, or moves from early intervention into 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 gets up to speed on goals far faster than one starting cold.
If therapy ends and you're watching for regression or wondering about re-referral, even a monthly entry earns its keep. It doesn't have to stay intensive forever, but a time-stamped record of where your child stood at age 3, 4, and 5 turns out to be genuinely valuable if questions come up later.
Parents sometimes ask whether logs can be used in evaluations, and 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 sources of information, alongside standardized testing, observation, and dynamic assessment.[1]
What are the most common mistakes parents make with communication logs?
The biggest one is writing too rarely and then guessing. Trying to reconstruct a week from memory the night before a session is close to useless: write in the moment, or within a few hours at most.
Another is only logging the 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 information, not something to leave out.
Vagueness is its own problem. "She communicated well" tells your SLP nothing; specific words, contexts, and counts tell her something. And it's tempting to stop logging during good stretches, but that's exactly when you want the data, since it shows your SLP what conditions actually support progress.
Watch, too, for 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 first, then add what you think it meant if you want to.
Last, don't turn the log into a comparison against siblings or other kids. It's a record of your own child's trajectory, not a scoreboard. Skip entries like "still not doing what her brother did at this age." Thoughts like that belong in a conversation with your SLP, not in the data itself.
Can a communication log help me notice signs that therapy isn't working?
Yes, and this might be the most underrated use of the whole habit. If you've been in therapy three or four months and the log shows no new words, no new contexts, and no drop in how often breakdowns happen, that's worth raising directly with your SLP.
Progress benchmarks vary by child, diagnosis, and starting point, so there's no single number that signals a problem on its own. But ASHA guidance on service delivery says progress should be monitored regularly, and that a 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 keeps you from waving off a real plateau as "just a bad week" when it's actually been six weeks running.
If you're worried progress has stalled and want a second opinion, the log is exactly what a new evaluating SLP will want to see, so bring it along. Our piece on what to expect from speech therapy and your speech therapist covers what that process typically looks like.
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 yourself. Useful when you're tired and busy, which is most of the time.
Is there research behind using communication logs this way?
Direct studies on communication logs as a standalone intervention are thin. Nobody has run a randomized trial pitting "log" against "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 programs that work.
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 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 something that's more clinical common sense than a tested intervention in its own right.
The closest thing to direct 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 may help your child partly just by sharpening your attention.
Frequently asked questions
What should I include in a communication log for a 2-year-old?
Focus on new words or word approximations, whether your child said them on their own or needed a prompt, gestures like pointing or reaching, and any communication breakdowns. Jot down the context too: mealtime, play, bath. At this age, vocabulary size and whether your child is combining two words are the data points your SLP cares about most. 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 that you could reconstruct what happened, not so detailed that you burn out. A date, the specific word or gesture, whether it was spontaneous or prompted, and a one-line note on context is genuinely enough, four or five fields per entry at most. If an entry takes more than two minutes, you'll stop doing it. 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, the exact word or utterance, spontaneous or prompted, context (where, who, activity), and notes. Google Sheets syncs across devices, shares with your SLP via a link, and sorts or filters by date. If you want to start right now, copy those six column headers and fill in one row from memory as a practice run.
How do I log communication if my child doesn't use words yet?
Log every intentional act: reaching toward something, pointing, bringing you an object, vocalizing while making eye contact, using a facial expression to respond. Note whether it seemed aimed at a person or looked self-directed. For AAC users, log each symbol access. Pre-verbal communication is rich data, and your SLP needs it to figure out where your child sits in the developmental 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 do. 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 isn't a crisis. Write what you remember, note that those entries came from memory rather than real time, and move on. The real mistake is letting guilt about a missed week turn into abandoning the log altogether. 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 put together 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 do.
Can a communication log help with an autism diagnosis or re-evaluation?
It can support the process, though it isn't a diagnostic tool on its own. Evaluating psychologists and SLPs often ask for developmental history and current communication patterns, and a dated log gives them real observations instead of reconstructed memory. For autism evaluations especially, context-dependent patterns, like words that only appear 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, like drilling a specific sound or rehearsing a scripted phrase. A communication log is an observational record of whatever happens naturally across the day. Both matter: the homework sheet targets a skill in a controlled setting, while the log tells you whether that skill is actually showing up in real life.
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 saying you've been keeping notes on what you're seeing at home and asking if it would help to share them. Most therapists say yes. If yours discourages parent input, that's worth treating as a red flag about the 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 purpose. Functional echolalia, like repeating "do you want a snack?" to mean "yes I want a snack," is different from non-functional echoing, and 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 entries. The fastest system is a running phone note: 15 to 30 seconds per entry in the moment, then a five-minute review before the session each week. It's a small time cost next to the payoff in better-targeted therapy, and it's the kind of homework that makes a 30-minute session worth far more.
At what age should I start keeping a communication log?
As soon as you have concerns, whatever your child's age. If they're under 3, you may already be in or pursuing early intervention, and the log helps that team right away. [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.
