If your child has been referred for therapy, it can feel like you suddenly need to learn a whole new language.
PT. OT. Speech. ABA.
What does each one actually do? How are they different? And why might your child need more than one?
The simplest answer is that each therapy looks at a different part of how a child functions in everyday life. There can be overlap between them—and that is a good thing. Children do not experience movement, communication, play, behavior, feeding, and independence as separate pieces. All of those skills work together throughout the day.
Here is a simple breakdown.
Physical Therapy: Helping Children Move and Participate
Pediatric physical therapy focuses primarily on movement and physical function.
A physical therapist looks at how a child moves through their world and what may be making movement harder. Physical therapists evaluate and treat children of all ages who have difficulty with mobility or physical function. The American Physical Therapy Association describes PT as helping people improve movement, function, mobility, and participation.
For a child, PT might work on:
Sitting, crawling, standing, or walking
Balance and coordination
Strength and endurance
Running and jumping
Going up and down stairs
Moving safely across uneven surfaces
Getting on and off the floor
Keeping up with peers on the playground
Using walkers, braces, or other mobility equipment
PT is not just about whether a child can perform a movement. We also care about whether the child can use that skill during real life.
For example, walking 20 feet in a therapy session is helpful. But ultimately, we want that child to be able to walk across the classroom, get outside to the playground, move through the grocery store with family, or participate in whatever activities are important to them.
Occupational Therapy: Helping Children Do Everyday Things
The word occupational can be confusing when we are talking about children. A child's “occupations” are not jobs—they are the activities that make up childhood.
That includes playing, eating, dressing, learning, sleeping, participating at school, interacting with others, and becoming more independent.
The American Occupational Therapy Association defines OT as helping people participate in the everyday activities they need and want to do. For young children, that can include play, feeding, routines, toileting, movement skills, community participation, and other daily activities.
An occupational therapist might work on:
Fine-motor skills
Using utensils
Dressing and fasteners
Toileting routines
Handwriting and pre-writing skills
Cutting with scissors
Using both hands together
Sensory regulation
Attention and participation
Play skills
Visual-motor skills
Feeding participation
Using adaptive equipment
Becoming more independent with daily routines
OT often asks:
“What is this child trying to do in everyday life, and what is getting in the way?”
Sometimes the barrier is strength or coordination. Sometimes it is sensory processing. Sometimes the environment needs to be changed. Sometimes a child needs a different way to accomplish the task.
OT looks at the whole picture.
Speech Therapy: Helping Children Communicate—and Much More
Most people think of speech therapy as helping a child pronounce sounds correctly.
That is part of it, but speech-language pathologists do much more.
According to the American Speech-Language-Hearing Association, SLPs evaluate and treat speech, language, communication, and swallowing disorders.
A pediatric SLP may help with:
Understanding language
Using words and sentences
Speech sounds and articulation
Being understood by others
Social communication
Asking for help or expressing needs
Following directions
Conversation skills
Stuttering or fluency
Voice
Augmentative and Alternative Communication (AAC)
Feeding and swallowing
Communication does not have to mean spoken words. Children may communicate through speech, gestures, signs, pictures, communication devices, or a combination of methods. ASHA recognizes all of these as valid communication approaches and describes SLP treatment as helping children communicate effectively in their everyday routines.
SLPs may also specialize in pediatric feeding and swallowing. Feeding is often a team effort because safe and successful eating can involve communication, oral-motor skills, sensory processing, positioning, movement, and medical factors.
Applied Behavior Analysis: Helping Children Learn Skills and Change Patterns of Behavior
Applied Behavior Analysis, or ABA, focuses on understanding why behavior happens and how learning occurs.
Behavior analysts look at what happens before and after a behavior, what purpose that behavior may be serving, and what skills the child may need instead.
ABA is commonly used with children with autism and other developmental disabilities. The Behavior Analyst Certification Board describes ABA as applying principles of behavior and learning to help individuals develop meaningful skills and address behaviors that interfere with daily life.
ABA may work on skills such as:
Communication
Following routines
Increasing independence
Self-care skills
Play
Social participation
Transitioning between activities
Tolerating changes in routines
Safety skills
Learning new skills
Reducing behaviors that interfere with learning, safety, or participation
A good ABA program should be individualized to the child and family's priorities.
The goal should not simply be to make a child behave or appear more like everyone else. The focus should be on helping the child communicate, participate, stay safe, gain independence, and develop skills that improve everyday life.
Why Do the Therapies Overlap?
Because children are whole people.
Imagine a child who struggles during mealtimes.
An SLP might evaluate chewing, swallowing, oral-motor skills, or communication during meals.
An OT might address utensil use, sensory responses to food, seating, or participation in the mealtime routine.
A PT might help with positioning, trunk control, or physical stability needed for safe eating.
An ABA team might help build predictable routines, teach communication related to meals, or address behaviors that interfere with participation.
Everyone is looking at the same child—but through a different professional lens.
That does not mean four people should work on exactly the same goal. It means the team should communicate so each discipline contr
ibutes its expertise.
How Do I Know Which Therapy My Child Needs?
You do not have to figure that out by yourself.
Start with what you are noticing in everyday life.
Maybe your child:
Falls much more than other children their age.
Is not yet walking or struggles to keep up physically.
Has difficulty using utensils or getting dressed.
Becomes overwhelmed by everyday sensory experiences.
Has difficulty communicating wants and needs.
Is hard for others to understand.
Has trouble chewing or swallowing.
Struggles with routines, transitions, safety, or learning new skills.
Those concerns can help determine which professional evaluation may be appropriate.
Sometimes one therapy is enough. Sometimes several disciplines are helpful. And those needs can change as a child grows.
At WHALE, We Want Therapy to Work in Real Life
At WHALE, our goal is not simply for a child to perform a skill inside a therapy session.
We want that skill to matter after therapy is over.
Can the child use it in the classroom?
On the playground?
During lunch?
With friends?
At home?
In the community?
That is why collaboration is such an important part of our therapy philosophy.
A physical therapist, occupational therapist, speech-language pathologist, behavior analyst, teacher, caregiver, and parent may all notice something different.
We believe everybody at the table knows something the rest of us don't.
When we share that knowledge, we gain a much better understanding of the child—and a much better opportunity to help that child participate fully in everyday life.
The Short Version
PT = movement and mobility
OT = everyday skills, independence, sensory and functional participation
Speech = communication, language, speech, feeding and swallowing
ABA = learning, behavior, routines, safety and functional skill development
Different tools. Different expertise. One child.
And the best therapy is not just about what happens during an appointment. It is about helping children use their growing skills where they matter most—in everyday life.
