TL;DR
Snap Core First works best for toddlers when you shrink the grid to 9 to 16 cells, swap default symbols for real photos of your child's world, add only the words they need right now, and model every word yourself before expecting them to use it. These four moves take about an hour and make the device feel like theirs.
Snap Core First is a symbol-based AAC (augmentative and alternative communication) app made by Tobii Dynavox. It runs on iPad and Windows tablets and uses a grid of symbols a child taps to build messages. Depending on which vocabulary you load, you'll see either LAMP Words for Life or the Snap + Core First set, both built to grow with a child from first words through full sentences.
For toddlers, the app has a lot going for it: clear symbols, a fully editable grid, and ready-made starter pagesets from Tobii Dynavox aimed at early communicators. The catch is that the default layout has dozens of cells and assumes more visual scanning ability than most two- or three-year-olds have. It can work beautifully for a toddler, but only once you've done some setup first.
If you're not sure whether your child needs AAC at all, start with a licensed speech-language pathologist. The American Speech-Language-Hearing Association [1] notes that AAC should be considered whenever someone can't meet their communication needs through natural speech alone, which includes toddlers with autism, childhood apraxia of speech, or global delays. Early access to AAC doesn't slow speech development; a large body of evidence reviewed by ASHA shows the opposite. Our guide to AAC devices covers the broader landscape if you want to compare options.
As of 2024, Snap Core First runs around $299.99 a year as a subscription or $599.99 as a one-time purchase, though Tobii Dynavox frequently offers it free or subsidized through school districts and insurance funding [2]. Ask your SLP about funding routes before paying out of pocket.
Choosing the right grid size
Grid size is the single most important setting to change. The default adult vocabulary loads with 42 or more cells per page, which is too much for most toddlers to process visually or motorically.
For a child under three, start with a 2x3 or 3x3 grid (4 to 9 cells). For a three- to four-year-old who's already pointing and sharing joint attention, a 3x4 or 4x4 grid (12 to 16 cells) makes sense. You can grow the grid later; shrinking it once a child is frustrated is much harder than expanding it once they're succeeding. To change grid size: go to Edit Mode (the pencil icon), tap Page Settings, then set your Row and Column count. The app reflows existing symbols automatically, so it's worth checking which ones survive the change.
Research backs up starting small. A 2021 study in the journal Augmentative and Alternative Communication found that children who began with smaller display sizes learned symbols faster at first than those started on larger displays [3]. That's not the only variable that matters, but the effect shows up often enough that most SLPs lean toward fewer cells early on.
| Child age / profile | Recommended starting grid | Cells |
|---|---|---|
| Under 24 months, very early communicator | 2x2 or 2x3 | 4 to 6 |
| 24 to 36 months, emerging communicator | 3x3 | 9 |
| 36 to 48 months, some symbol recognition | 3x4 or 4x4 | 12 to 16 |
| 4+ years, consistent device user | 5x7 or larger | 35+ |
Building the vocabulary
Start with core vocabulary: words like "more," "stop," "go," "help," "want," "no," "yes," "eat," "drink," and "my turn" that work across hundreds of situations. Core words make up roughly 80% of what people say every day, even though they're a tiny fraction of all possible words [4]. Load those first.
Then add fringe vocabulary: the specific nouns and verbs that matter in your child's life right now. If they love trucks, add "truck." If bathtime is a daily battle, add "bath," "water," "done." These words come up less often but carry more motivation, and motivation matters enormously for a toddler who doesn't yet understand why they're supposed to tap a screen.
To add a button: enter Edit Mode, tap an empty cell (or long-press an existing one to replace it), choose Add Button, then give it a label, a symbol or photo, and a speech output, which is what the device says aloud when tapped. For toddlers, keep the label and speech output identical and simple, one word at a time.
A few things worth knowing as you build the set out. Action words tend to do more work than nouns: "go," "help," and "open" let a toddler request things happening, where "ball" or "cookie" alone only labels an object. Skip pairing opposites like "hot/cold" or "big/little" in the same early set, since they confuse symbol discrimination before a child has stable categories. And go slow: adding three to five new words a week gives most toddlers time to see each one modeled repeatedly before the next batch shows up.
Photos or symbols?
Honestly, it depends on the child, and you may need to try both.
Snap Core First uses SymbolStix symbols by default: simple, colorful line-art figures. Research generally shows that children who already grasp that pictures represent objects (representational understanding) can learn AAC symbols whether they're photos or drawings [5]. But for toddlers who are very early in symbolic thinking, real photos of their actual objects and people often work better as a starting point.
To swap a symbol for a photo: Edit Mode, tap the cell, choose Edit Button, tap the current image, then select Take Photo or Choose from Library. Use photos of the actual object in your house, not stock images: the cup from your kitchen, not generic cup clipart.
Some SLPs recommend photos for three to six months before gradually transitioning to symbols as understanding builds. Others go straight to symbols, since photos can make generalization harder (a child learns "my red cup" instead of "cup" as a category). Talk this through with your SLP based on your child's profile.
One move that's almost universally worth making: put a real photo of your child's face on their "me" or name button, and photos of immediate family on a People page. Toddlers light up at familiar faces, and it gives them vocabulary for the people who matter most.
Access and touch settings for toddlers who struggle with the screen
Most toddlers can direct-touch a screen fine if the cells are large enough, which is one more reason to start with a smaller grid. A 3x3 grid on an iPad gives each cell roughly 2.5 by 2.5 inches, very manageable for small hands.
If your toddler has motor difficulties that make direct touch unreliable, Snap Core First supports single switch scanning, two-switch scanning, head tracking through the front camera, and eye gaze if you connect a Tobii eye tracker. These aren't beginner setups, and you'll want an SLP or AT specialist to configure them, but they're good to know about.
For most toddlers without significant motor impairments, two settings make direct touch much easier. First, adjust the touch delay: go to Settings, then Access, then Touch, and increase the minimum hold time before a touch registers. This cuts down on accidental activations from a toddler dragging a palm across the screen; a 0.1 to 0.3 second delay makes a real difference. Second, consider Key Guard, a physical plastic overlay with holes cut out for each cell that prevents accidental presses between buttons. Tobii Dynavox sells these for common tablets for roughly $50 to $80, often covered by the same funding that covers the device [2].
If your child has apraxia of speech or childhood apraxia of speech, motor planning for AAC is specialized territory, so lean on an SLP with CAS experience to guide the access setup.
How do you organize pages in Snap Core First for a toddler?
Toddlers do better with fewer page levels. Deeply nested folders, where you tap "food" to get to a food page, then tap "fruit" to get to a fruit page, add motor and cognitive steps that defeat a toddler before they've said anything.
A good starting structure is one main page with core vocabulary (9 to 16 cells) and no more than two or three linked sub-pages for high-frequency fringe words: a People page, an Activities page, maybe a Food page. That's it to start. Every page should be reachable in one or two taps from anywhere.
Snap Core First comes with a built-in vocabulary called LAMP Words for Life (LWF), built around a motor-learning approach where every word always lives in the same location, even as the vocabulary grows. That consistency helps toddlers and kids with motor planning difficulties in particular. Load LAMP instead of the standard Snap Core First vocabulary and the grid starts out denser, but every word stays findable in the same spot, which cuts down on the searching. Ask your SLP which vocabulary approach fits your child before you commit to one.
To link pages: go into Edit Mode, tap a cell, choose Edit Button, and set the Action to "Go to Page," then pick or create the destination. It's also worth setting a "Home" button on every sub-page so your child can always find the way back.
How should parents model AAC use so toddlers actually learn it?
Buying and setting up the device is step one. Modeling is the whole rest of the job.
Aided Language Input (ALI) means an adult points to or presses AAC symbols while speaking normally. The research is clear on this: children need to see their communication partners use the device before they'll use it themselves [4]. The general guidance is to model at least 100 to 200 symbols a day across natural routines, though nobody has great data on the precise number. The most-cited figure comes from clinical practice guidelines rather than a controlled trial.
In practice, this looks like narrating breakfast with the device: you press "eat," you press "more," you press "all done" when the bowl is empty. You're not asking your child to press anything yet, just showing them that the device is how people talk.
Expectation-free modeling for the first several weeks is a real thing, and some families find it hard because they're eager to see the child communicate. But pushing a toddler to "use words" on the device before they're ready just creates frustration on both sides. Give it time.
A few things worth doing: model during the child's preferred activities, since motivation runs highest when something fun is happening, and slow down. Tap a symbol, wait three to five seconds, let the child respond however they can, then tap again. A few things to skip: don't quiz the child ("What's this?" or "Show me where ball is" feel like tests, not conversations), and don't put the device away when it's inconvenient. It should be available essentially all of the child's waking hours. Communication doesn't pause because you're cooking dinner.
For families also working on early intervention goals or speech therapy at home, ALI fits directly into those programs, and your SLP can show you the specific modeling targets for your child's level.
How do you keep a toddler interested in using Snap Core First?
Toddler motivation is everything. The device has to connect to things they actually care about.
Start with the voice. Snap Core First lets you change the text-to-speech voice under Settings, then Speech, and some children respond much better to a child-sounding voice than the default adult one. Tobii Dynavox includes several voices through the Acapela or Nuance engines, and many families find that a voice closer to the child's own age keeps them more engaged.
Make sure the device gets them things they want. If your toddler loves bubbles, put a bubble button on the device, and when they press it, bubbles should actually appear. That direct consequence, pressing a button and getting the thing you wanted, is how toddlers learn communication works.
Social games help too. Cause-and-effect routines like "ready, set, go," where the child presses "go" and something fun launches, or pressing "more" to continue tickles, build AAC use without it feeling like therapy.
Don't let the screen double as a passive entertainment device. If the tablet running Snap Core First also runs YouTube, toddlers will choose passive viewing over communicating every time. Use a dedicated device, or lock the home screen down hard.
Some families pair a full AAC system with something lighter for on-the-go use. If you want a lower-friction companion app to reinforce vocabulary between sessions, Little Words is an AI-powered speech companion designed for neurodivergent kids that adapts to your child's level without requiring the full setup of a dedicated AAC system.
What should you do if a toddler refuses to touch the device at all?
Device refusal is common and rarely permanent, and a few things tend to cause it.
Sometimes the device was introduced with too much pressure. If an adult held it up in front of a toddler and said "say more," the child may start associating the device with demands and avoid it. Back off completely for one to two weeks: put the device on the table during play, model on it yourself, and don't prompt the child at all.
Sometimes the vocabulary just doesn't match their interests. A device loaded with "bath" and "eat" gives a train-obsessed toddler no reason to touch it. Watch what your child actually plays with and talks about, even through sounds or gestures, and load vocabulary for those exact things.
Sometimes it's the motor access. If tapping is physically effortful or unreliable, toddlers give up fast. Review the touch settings, try a key guard, and consider whether the grid is too small to tap accurately.
And sometimes it's sensory: some kids are averse to the feel of a screen or the sound of the synthetic voice. A matte screen protector changes the tactile feel significantly, and it's worth experimenting with voice settings or volume too.
If refusal lasts more than a few weeks despite these changes, bring it up with your SLP. Sometimes the AAC system itself isn't the right fit, and a different format, like low-tech communication boards or PECS, works better as a bridge. You can also read more about autism spectrum speech therapy approaches that sometimes pair with or precede AAC.
How do you work with a speech therapist to customize Snap Core First?
You shouldn't be doing all of this alone. An SLP who specializes in AAC can assess your child's language level, motor abilities, and sensory profile, and use that to make specific recommendations about vocabulary, grid size, and access that would otherwise take you months of trial and error to work out.
In the United States, children under three who qualify for early intervention can receive AAC support through their state's Part C early intervention program at no cost to the family under IDEA (Individuals with Disabilities Education Act, 20 U.S.C. § 1400 et seq.) [6]. Children three and older may receive services through a school district IEP under Part B of the same law.
ASHA's position on AAC is explicit: "AAC is an appropriate intervention for individuals who have not developed natural speech and language skills sufficient to meet their daily communication needs" [1]. That's language you can use directly when advocating for your child's services.
For remote families, or anywhere local AAC specialists are scarce, online speech therapy with an SLP credentialed in AAC is a real option, and many insurance plans cover it after the COVID telehealth expansions.
Ask your SLP directly about their experience with Snap Core First (not every SLP knows this app well), whether they recommend LAMP or a different vocabulary approach for your child, how often they want to review and update the device settings, and whether they'll do a home visit or send a video of themselves modeling so you can match their technique.
Bringing your customized device to every session and showing the therapist exactly what your setup looks like will get you further than any verbal description could.
Growing your toddler's vocabulary on the device isn't a one-time setup job, it's ongoing work. Expect to update it every month or two, especially in the early phases. The clearest sign it's time to expand is saturation: your child is using nearly every button on the current grid regularly and clearly wants to say things the device doesn't have words for. That's your cue to add cells or open a new sub-page, but do it in small doses. Add three to five new words at a time, and model each one heavily for a week before introducing the next batch. Words that go unused deserve the same attention as words that get worn out. If a button sits untouched for four to six weeks and your child shows no interest in it, swap it for something more motivating. There's no reason to keep a word in place just because a list somewhere said it should be included. At the same time, pay attention to what your child is trying to say that the device can't capture yet. Sounds, gestures, and behaviors that seem communicative but don't map to any current button are exactly the vocabulary you should be adding next. Snap Core First tracks button presses automatically, and checking those logs every few weeks tells you plainly what's getting used and what's idle. Bring that data to your SLP sessions too. And once your child hits around age four and is using the device consistently and with motivation, it may be time to talk with your SLP about a larger vocabulary set and more complex sentence structures. That's a conversation worth having, and honestly, a good problem to have.Frequently asked questions
What age can a toddler start using Snap Core First?
The app has no built-in minimum age. In practice, kids as young as 12 to 18 months can start with a very small grid (4 to 6 cells) if they can physically touch a screen and have some reason to communicate. ASHA supports introducing AAC early, and notes that research does not show AAC delays speech development. Your SLP is the right person to judge readiness.
How long does it take to set up Snap Core First for a toddler?
Basic setup, meaning grid size, swapping in a few photos for symbols, and adding ten to fifteen core words, takes about one to two hours if you're starting from a template. Building a fully customized vocabulary is a slower project, more like thirty to sixty minutes a month of ongoing tweaks. Don't try to finish it all in one sitting; get a workable starter set live and build from there.
Is there a free trial or free version of Snap Core First?
Tobii Dynavox offers a free 30-day trial for iPad and Windows. After that, it's roughly $299.99 a year as a subscription or about $599.99 as a one-time purchase. Plenty of families get it free through school district funding, Medicaid, or private insurance, so it's worth asking your SLP or an AT specialist about funding routes before paying out of pocket.
Can Snap Core First be used offline?
Yes, fully. Once it's downloaded, the symbols, audio, and navigation all work with no internet connection at all, which matters a lot when your toddler is using it in the car, at the playground, or in a waiting room. The only things that need connectivity are downloading extra content packs or syncing with the Tobii Dynavox cloud backup.
How is Snap Core First different from Proloquo2Go for toddlers?
Both are solid, well-researched AAC apps. Proloquo2Go (AssistiveWare) uses SymbolStix or PCS symbols and offers a strong LAMP-compatible vocabulary called Unity. Snap Core First builds LAMP Words for Life in natively and has a somewhat simpler setup process. For toddlers, day-to-day differences between the two are minor. What matters more is whether your SLP is already familiar with the app you pick.
Will using AAC stop my toddler from developing natural speech?
No, and this is the myth that just won't die in AAC circles. Several systematic reviews, including a 2014 meta-analysis in AJSLP covering 27 studies, found that AAC does not get in the way of speech development and often helps it along. Both ASHA and the American Academy of Pediatrics back early AAC access. That worry doesn't need a place in your decision-making anymore.
How do I add my toddler's favorite characters or objects as symbols?
Go into Edit Mode, tap a cell, choose Edit Button, then tap the existing image and select Choose from Library. From there you can pull in any photo from your camera roll, including screenshots of a favorite character (copyright rules apply to commercial use, not private family use at home). When you can, use a photo of the actual toy or object rather than a stock image, since that helps kids generalize the word.
What is LAMP Words for Life and should my toddler use it?
LAMP Words for Life is a motor-learning vocabulary system where each word stays in the same spot on the grid permanently, even as the display expands. That fixed location helps kids build muscle memory for words they use often, which is particularly helpful for children with motor planning challenges like childhood apraxia of speech. It works well for many toddlers, but it's a decision to make together with your SLP.
How many words should a toddler have on their AAC device?
Start small: 9 to 16 words total, mostly core vocabulary (more, help, stop, go, want, no, yes, eat, drink, all done), with fringe vocabulary filling in around that. Once your child starts engaging with the starter set, add three to five new words every week or two. There's no upper limit; the vocabulary just keeps growing alongside the child for years.
Can siblings and grandparents learn to use the device too?
Yes, and honestly they should. Consistency across everyone who talks to your toddler is one of the strongest predictors of whether AAC succeeds. Anyone who spends real time with your child should know where the core words are and should model on the device during everyday interactions. Tobii Dynavox has free tutorial videos on its website, and it's worth asking your SLP for a short family training session too.
How do I know if my toddler's AAC setup is working?
Over six to twelve weeks, watch for the child approaching the device on their own, using it to start a conversation rather than just answer, and searching for a word even when it's not on the grid yet. The usage logs in Snap Core First should show button presses climbing over time. If none of that shows up after two to three months of steady modeling, take the data to your SLP and rework the setup together.
Does insurance cover Snap Core First for a toddler?
It can. Medicaid covers AAC devices and software when they're medically necessary, and you'll typically need an SLP evaluation plus a letter of medical necessity. Private insurance varies a lot from plan to plan. Some states fund AAC through early intervention programs at no cost for kids under three. An AT specialist, an SLP who focuses on AAC funding, can walk you through the process.
Should I use Snap Core First on a dedicated device or our family iPad?
A dedicated device is much better. When the AAC device doubles as the family entertainment iPad, toddlers gravitate toward passive content and skip the harder work of communicating. If you have to share a device, use Guided Access (iOS Settings > Accessibility) to lock the iPad into Snap Core First during communication time.
