If your pediatrician or school has recommended therapy for your child, you've probably heard a lot of acronyms: ABA, SLP, OT, PT. It can feel like learning a new language at the worst possible time.
Here's the truth: pediatric therapy isn't one thing. It's a category that includes multiple types of specialized support, each designed to address different challenges. Understanding the differences between these therapies is the first step toward figuring out which one — or which combination — your child actually needs.
This guide breaks down the four most common types of pediatric therapy services. We'll explain what each one does, who provides it, and when it makes sense to pursue it. For a broader overview of pediatric therapy as a whole, start with our complete guide to pediatric therapy.
Key Takeaways
Before you dive in, here's what matters most:
- The four most common pediatric therapies are ABA, speech, occupational, and physical therapy.
- Each modality targets different developmental areas and is delivered by specialists with distinct credentials.
- Many children benefit from more than one type of therapy at the same time.
- Choosing the right therapy starts with understanding what your child needs help with most.
The Big 4 Modalities
While there are other specialized therapies (like feeding therapy or vision therapy), these four represent the core of what most families encounter:
- Applied Behavior Analysis (ABA): Evidence-based therapy for children with autism that teaches skills and reduces challenging behaviors through structured practice and positive reinforcement.
- Speech Therapy (ST): Delivered by a Speech-Language Pathologist (SLP), this addresses communication delays, articulation issues, social communication challenges, and feeding difficulties.
- Occupational Therapy (OT): Helps children develop fine motor skills, sensory processing abilities, and the daily living skills needed to participate fully in childhood activities.
- Physical Therapy (PT): Focuses on gross motor skills, movement, balance, coordination, and physical development.
The right therapy depends entirely on your child's specific strengths, challenges, and goals. Let's look at each one in depth.
ABA Therapy
ABA therapy is the gold standard treatment for children with autism spectrum disorder (ASD). It's an evidence-based approach grounded in the science of learning and behavior. The goal of ABA is to increase helpful behaviors and decrease behaviors that interfere with learning or daily functioning.
What ABA Looks Like in Practice
ABA therapy is highly individualized. A Board Certified Behavior Analyst (BCBA) conducts an initial assessment, identifies specific goals based on your child's needs, and designs a treatment plan. Therapy is typically delivered by a Registered Behavior Technician (RBT) under the BCBA's direct supervision.
Sessions can take place in your home, a clinic, your child's school, or out in the community. Therapy might look like playing with toys, practicing communication, working through daily routines, or navigating social situations — all while a trained therapist uses data to track progress and adjust the plan.
Common ABA Techniques
ABA isn't a single method — it's a framework that includes a variety of teaching strategies:
- Discrete Trial Training (DTT): Breaking skills into small, teachable steps with repeated practice and immediate feedback.
- Natural Environment Teaching (NET): Teaching skills during natural play and daily routines rather than at a table.
- Pivotal Response Treatment (PRT): Focusing on "pivotal" skills like motivation and self-management that lead to improvements in other areas.
Who Provides ABA?
ABA therapy involves two key roles:
- BCBA (Board Certified Behavior Analyst): Master's or doctoral-level clinician who designs and supervises the program.
- RBT (Registered Behavior Technician): Paraprofessional who delivers therapy sessions under BCBA supervision.
When ABA Makes Sense
ABA is most commonly recommended for children with autism, but it can also help children with other developmental delays or behavioral challenges. Research shows that early, intensive ABA (20 to 40 hours per week for young children) leads to significant gains in communication, social skills, and adaptive behavior.

Speech Therapy
Pediatric speech therapy addresses a broad range of communication challenges. A Speech-Language Pathologist (SLP) evaluates and treats issues with spoken language, understanding language, social communication, voice, fluency (stuttering), and feeding/swallowing.
What Speech Therapy Addresses
Speech therapy isn't just about pronunciation. SLPs work on:
- Articulation: Saying sounds and words clearly (e.g., a child who says "wabbit" instead of "rabbit").
- Expressive language: Using words, sentences, and gestures to communicate needs and ideas.
- Receptive language: Understanding what others say.
- Social communication (pragmatics): Knowing how to use language in conversation, take turns, make eye contact, and read social cues.
- Feeding and swallowing: Helping children who have trouble eating safely or who are extremely picky eaters.
What a Session Looks Like
Speech therapy sessions are often play-based, especially for younger children. An SLP might use toys, books, games, or structured activities to practice target sounds or vocabulary. Older children might work on conversational skills, storytelling, or reading comprehension strategies.
Many SLPs incorporate parent coaching so you can practice strategies at home between sessions. Consistency is key to progress in speech therapy.
When Speech Therapy Makes Sense
If your child isn't meeting language milestones, if they're difficult to understand, or if they're struggling to connect with peers because of communication challenges, speech therapy is worth pursuing. Speech delays are one of the most common reasons families seek early intervention services.

OT vs. PT
Parents frequently confuse OT and PT because both involve movement and physical skills. But they target very different things.
Occupational Therapy (OT)
Occupational therapy helps children participate in the "occupations" of childhood: playing, learning, self-care, and interacting with others. OT focuses on:
- Fine motor skills: Using hands and fingers for tasks like writing, buttoning clothes, or using utensils.
- Sensory processing: Helping children who are over- or under-responsive to sensory input (sounds, textures, movement, etc.).
- Visual motor skills: Hand-eye coordination needed for tasks like catching a ball or copying from a board.
- Self-care and daily routines: Dressing, grooming, feeding, and other activities of daily living.
Physical Therapy (PT)
Physical therapy focuses on gross motor skills — the big body movements that allow children to move through the world. PT addresses:
- Strength and muscle tone: Building the physical foundation needed for movement.
- Balance and coordination: Learning to walk, run, jump, climb stairs, and navigate obstacles.
- Gait and movement patterns: Correcting the way a child walks or moves to prevent injury and improve function.
- Recovery from injury: Helping children regain mobility after surgery, fracture, or illness.
Can a Child Do Both?
Absolutely. OT and PT often work together. A child with cerebral palsy, for example, might see a PT for walking and mobility and an OT for hand function and self-care skills. The two disciplines complement each other beautifully.

Choosing the Right Therapy
The short answer: you don't have to choose alone. Your child's pediatrician, developmental specialist, or early intervention coordinator can help guide you toward the right services based on evaluation results and your child's specific needs.
That said, here's a general framework to think through:
- If your child has autism or significant behavioral challenges → Start with ABA.
- If your child isn't talking or is hard to understand → Start with speech therapy.
- If your child struggles with handwriting, self-care, or sensory sensitivities → Start with OT.
- If your child has delays in walking, balance, or gross motor skills → Start with PT.
Remember: These aren't mutually exclusive. Many children receive two or three types of therapy simultaneously. For more on play-based approaches, read: Benefits of play-based therapy for toddlers.
The most important thing is to start somewhere. Early intervention makes a difference, and it's never too late to ask for help.

FAQ
Frequently Asked Questions
Can my child do ABA and speech therapy at the same time?
Yes, and this combination is very common for children with autism. ABA therapists and SLPs often collaborate to reinforce communication goals across both therapies. Just make sure the two providers are communicating with each other and with you.
How do I know if my child needs OT or PT?
If you're not sure, ask your pediatrician for a referral to both for evaluation. The therapists themselves will determine whether services are appropriate. In general, if the challenge involves using hands and fingers or sensory issues, it's OT. If it's about walking, running, or large body movements, it's PT.
Does insurance cover all these therapies?
Coverage varies widely by plan and by state. Most private insurance and Medicaid plans are required to cover medically necessary therapy for children, but what qualifies as "medically necessary" is determined by your plan. Always verify coverage before starting services.
How long does therapy last?
This depends entirely on your child's goals and progress. Some children complete a focused course of speech therapy in six months. Others receive ABA or OT services for several years. Therapy should always be goal-driven with regular reassessment.
