For Clinicians
You see the same moment repeatedly: a family has just received a diagnosis, and what they need in the next ninety days is language access β not in six months, when the services start. This page exists so you can hand them something in that moment, at no cost to your clinic.
What we're asking of you β and what we're not
No inventory
You never stock, buy, or resell anything. Nothing sits on your shelf and nothing appears on your budget.
No endorsement
We're not asking you to recommend a brand. Adding a resource to a handout list is not a clinical endorsement, and we don't present it as one.
No billing relationship
The purchase happens between the family's funding program and us. Your clinic is not in the transaction at any point.
The single ask is this: if you keep a resource list, consider adding a line to it. The family does the rest, and the funding program decides. If the product doesn't hold up on its own merits when you look at it, it shouldn't be on your list β that's the correct filter and we're content to be judged by it.
The evidence, stated honestly
You will be asked to justify anything you hand out, so here is the evidence separated into what is established and what is not. We would rather you trust the second list than be surprised by it later.
Early visual language access matters for deaf and HoH children
The cost of delayed language access is documented and lasting. A 2024 study in Developmental Science found deaf children exposed to sign language before cochlear implantation outperformed both deaf peers without sign exposure and hearing peers on measures of spoken language β consistent with the position that sign access supports rather than competes with speech.
Dynamic presentation beats static for motor procedures
A meta-analysis of 26 studies (76 pairwise comparisons) found a medium overall advantage for animation over static pictures, rising to a large effect (d = 1.06) when the learning target is procedural-motor knowledge. Independently replicated in 2016. Producing a sign is procedural-motor knowledge, and movement and palm orientation are two of the five phonological parameters a static image cannot encode.
A spoken-vocabulary advantage for hearing infants
Controlled trials have not found that teaching signs to hearing babies produces a lasting spoken-vocabulary advantage. What has been observed is that signing caregivers were more responsive to their infants' nonverbal cues. No study has found sign exposure harmful to a hearing child. We present it as a caregiver-responsiveness benefit, not a language-acceleration claim.
The projection figures on our main page
The vocabulary-growth curve and the minimal-pair recognition chart are our models of the mechanism, not collected outcomes. They are labelled that way wherever they appear. We have not run a trial, and we don't imply that we have.

A sign is a movement, not a pose. Printed materials that show one frozen frame drop the movement and the palm orientation β two of the five parameters that distinguish one sign from another. This is why look-alike pairs are so often confused early on.
HoloCards are lenticular cards: tilt one and the sign performs in the child's hand. No screen, no battery, no application. They are designed for the ordinary moments β mealtimes, nappy changes, the car seat β where language actually gets learned.
How families obtain them at no cost:
- Ask your early intervention service coordinator (birth–3) or your school district's special education office (3–21) to consider assistive technology in your child's written plan.
- Assistive technology is defined broadly by federal regulation, and includes commercially available products.
- If the team approves it, the program purchases it and it is provided to your family.
Important and honest: approval is a decision your team makes, and it can go either way. Early intervention is also a payer of last resort, so insurance or Medicaid may be billed first, and some states operate a system of payments with sliding-scale fees. Ask your coordinator how it applies to you.
