The True Cost of Waiting: What Happens When a Blind Baby Has No Mobility Tool?

The first article in “The Cost of Waiting,” a series examining what happens when we fail to invest in appropriate mobility technology for young children with a mobility visual impairment or blindness.


There is a question we should be asking much earlier when a baby is diagnosed with a mobility visual impairment or blindness (MVI/B):


What will this MVI/B child use to move safely and independently while learning to stand and walk?


Too often, the answer is essentially: nothing yet.


And, everyone waits.

  • We wait for the child with an MVI/B to walk.

  • We wait for the child with an MVI/B to become more coordinated.

  • We wait until the child with an MVI/B is “old enough.”

  • We wait until the child with an MVI/B can supposedly understand a conventional cane.


And when a child cannot safely navigate without assistance, professionals and families may turn to whatever can be built from materials that are readily available—PVC pipe, wheels, handles, frames, and other components—to create an adaptive mobility device (AMD).


That ingenuity deserves recognition.

But it also tells us something important:


We have been trying to solve a problem that the marketplace has largely failed to solve.


The problem can't be that the child with an MVI/B isn't ready.

Imagine a sighted toddler who has learned to pull to stand.

The child reaches for something across the room.

They stand.

They take a step.

They fall.

They get back up.

They walk around a chair.

They discover something on the floor.

They move toward a parent.

They turn around and go somewhere else.


Nobody waits for that child to demonstrate that they are “ready for independent walking” before allowing them to practice independent walking.


The walking itself is part of how the child develops the skills to walk.


But for a blind baby, the situation is different.


Distance vision normally provides information about the environment a child uses to anticipate obstacles, understand where spaces open and close, maintain balance, locate people and objects, and decide where to move next.


When a baby cannot rely on vision, the child needs another way to receive that information.


That need does not begin when the child is three years old.

It begins when the child begins trying to move.


“Wait until they are walking” creates a circular problem


One of the most troubling assumptions in early mobility is that a child needs to be independently walking before receiving a tool that can help them learn to walk independently.


That creates a circular problem:

The child needs mobility to practice mobility.


A parent may understandably think:

“My child is taking steps independently, but let's go of the cane so maybe they're not ready for a mobility device.”

But walking ability should not determine whether a blind child is "ready for a mobility tool".

Blindness and mobility visual impairment are the only factors that qualify a child for a mobility tool. Yet, since the market has only produced adult-type devices, parents are given a front-row seat to watching their MVI/B child walk less as they mature.

But they are not developmental mobility specialists, engineers, or product designers. These loving parents follow the advice of wait for the child to "want to use the long cane" and to interpret their child's hesitation, frustration, or lack of exploration as evidence that the child isn't ready—when it is actually evidence that they need a mobility tool to move through the environment because they are blind. Sight isn't providing enough protection or information for the child to move confidently, and they need extended touch.


Young children are supposed to push boundaries.

They crawl somewhere they haven't been before.

They stand up.

They reach.

They walk toward something interesting.

They change direction.

They get stuck.

They figure it out.

That is development.


If a blind baby cannot safely engage in those experiences, the cost of waiting is not simply that the child walks later. It is the continued exposure of blind children to uncertain footing.


The MVI/B child may have many opportunities to learn through movement, but have you asked yourself is it fair to ask a blind baby to walk without extended touch feedback ensuring them their next step is clear?


What happens when there is no appropriate commercial tool?

This is where the PVC adaptive mobility device enters the story.

These recently published textbooks both provided 1970-era diagrams for homemade AMDs, instead of offering modern, more successful mobility tools for blind babies.

O&M professionals have long demonstrated extraordinary creativity in developing ways for children to move through their environments. Training materials and textbooks have included designs and instructions for creating adaptive mobility devices from materials such as PVC since the 1970s.


Why?

Because once trained O&M professionals entered the schools they recognized the problem immediately.

They met the child with an MVI/B who was unlike their sighted peer in the way they moved. Whethere intellectually capable or developmentally challenged, growing up without mobility tools showed up in their gait, pace and posture. These children were ill-prepared to learn to use an adult long cane.


It was reported that even the best students, after a full year of instruction, motivation, and parental follow-through well-oriented; were incapable of employing long cane skills correctly for path preview (Wiener, Wall Emerson, & Blasch, 2024; Lord & Bledsoe, 1961).


Seeing the need, these pioneers attempted to homemade devices, which at that time wasn't so extrodiary given that every graduate in O&M had first had to construct their own long canes to participate in blindfold lab courses.


AMDs were constructed during an era of a lot of experimentation necessary because thousands of blind children all across the US had entered their local schools during the ROP epidemic and the years that followed. Instructors believed in trying anything because the needs of these children were so outside of the typical educational method and adult long canes were the only option and they were not working. So, they tried push toys, push brooms, and eventually PVC pipe.


It would seem each of their designs worked a little bit, they stopped there. As the poor outcomes with these devices further supported the narrative that blind children would simply need to wait until they were ready.


Developing homemade AMDs was resourcefulness.

But resourcefulness is not the same thing as a functioning mobility technology industry.


A homemade device can be an important clinical innovation or prototype. It can help a professional think differently about an MVI/B child's needs.

But a child with a disability should not have to depend on whether their O&M specialist is handy with tools.


If AMDs worked for learners with a congenital MVI/B, Ambutech would be selling a lot more of them in child sizes.


If the homemade AMDs worked - there would be great demand for high-quality commercial AMD products and there is not.


A prototype is not a marketplace solution

There is another important distinction.

A device can work for one child and still not be a successful product.

A professional can create a clever solution for a particular student based on that child's:

  • height,

  • weight,

  • motor abilities,

  • environment,

  • family circumstances,

  • and specific mobility needs.


But transferring that solution to thousands of children requires an entirely different process.

A real product must be manufactured consistently.

  • It must be tested.

  • It must withstand everyday use.

  • It must accommodate growth.

  • It must have replacement components.

  • It must be available when a child needs it.


Professionals must be able to learn how to use it.

Families must be able to obtain it.

And, critically, its effectiveness needs to be evaluated.

That is what separates improvisation from innovation.


And then there is the other choice: the handheld device

When a commercially manufactured pediatric mobility tool are the same design as adult devivces, the alternatives have become variations on two familiar categories:

the long cane or the adaptive mobility device.

Both can have important roles.

But both can also place significant demands on a blind babies.

  • The child with the MVI/B must hold the device.

  • The child with the MVI/B must control it.

  • The child with the MVI/B must learn what the information coming through it means.

  • The child with the MVI/B must remember to use it.

  • The child with the MVI/B must locate it when they need it.

  • The child with the MVI/B must integrate the device into their movement.


For an older childwith the MVI/B, these may be reasonable and achievable skills.

For a baby with the MVI/B who is only just learning to stand and walk, they represent a very different developmental challenge.


And this is where we need to stop asking only:

“Can this child with the MVI/B develop the skills to use a cane or maintain a grasp on an AMD?”


We should also ask:

“What is the child with the MVI/B missing while they are waiting to be able to use one or the other handheld device?”


The real cost of waiting is developmental

The most important cost may be the one that never appears on an invoice.

A blind baby who is unable to move independently because they cannot solve the first problem, how to self-reliantly tell when the path is clear.


A seated child with an MVI/B encounters fewer problems to solve, resulting in less understanding of how to be a self-reliant mover.


A mobility tool brings self-reliance to the motor skill. With a Belt Cane the MVI/B child can move toward an obstacle and receive information through extended touch.

Go.

Stop.

Change direction.

Get stuck.

Discover a clear path.

Move forward.

That sequence matters.


It is not simply about getting from one place to another.


It is about learning:

“I have the information I need to move through my world.”


A child who repeatedly relies on a sighted adult to determine where they can safely go may learn a very different lesson:

“Someone else figures out where I can go.”


That difference can accumulate.

Day after day.

Month after month.

Year after year.


And the lost time cannot simply be recovered when a child eventually receives a conventional mobility device.



Children waiting to become independent have less opportunity to enjoy learning independence the hard way

This is the central mistake in the “wait until they are old enough” approach.

Independence is not a switch that turns on at a particular age.


It develops through experience.

Children become competent by doing.


With the right sensory information, children learn to solve problems by encountering problems.

With the right protective feedback, they learn to navigate by navigating.

They learn to interpret environmental information by receiving and responding to that information repeatedly through a tool that is always in the right place at the right time.

They learn confidence by discovering that they have the information they need to make something happen in their environment.


For a blind baby, that means providing mobility tools that enable access to meaningful mobility experiences during the same developmental period when sighted children are naturally gaining those experiences through distance vision.


The goal is not to force a child to walk before they are developmentally ready.

The goal is to remove the unnecessary barriers that prevent an MVI/B child from practicing the skills they are developmentally ready to learn.


The question we should be asking

Instead of asking:

“Is this child old enough (ready) to use a mobility device?”


we should be asking:

“What does this MVI/B child need right now to become a self-reliant mover when participating in the developmental experiences?”


That is a very different question.


It shifts the focus from the child's limitations to the tools available to support the MVI/B child's development.

It also changes how we think about innovation.


If the only choices available are:

Wait.

or

Make something yourself.


then we don't have an adequate pediatric mobility marketplace.

We have an unmet need.

And children with blindness or a mobility visual impairment should not be expected to bear the developmental cost of that unmet need.


They are valued members of our society.

They deserve tools designed for them.

They deserve tools that can be evaluated.

They deserve tools that can be manufactured consistently.

They deserve tools that professionals can prescribe without having to build them in a hardware store.


And they deserve those tools when they need them—not only when they have finally become old enough to use something designed for someone else.


Because the true cost of spending nothing on pediatric mobility isn't nothing.

The cost is paid in opportunities to move, explore, learn, participate, and become self-reliant.


And once we understand that cost, we have to ask a much harder question:

Why have we accepted improvisation and waiting as the standard for children with an MVI/B who need mobility technology the most?
