Maybe your pediatrician mentioned “a therapy evaluation,” or a teacher noticed your child struggling. Then come the acronyms: OT, PT, SLP. Understanding occupational therapy vs. physical therapy vs. speech therapy helps you ask better questions and reach the right specialist sooner.
This guide compares all three and explains next steps for families in Phoenix, Mesa, and across Arizona.
Key Takeaways
- Speech therapy helps children communicate, understand language, and eat and swallow safely.
- Occupational therapy helps children do everyday tasks like dressing, eating, handwriting, and handling sensory input.
- Physical therapy helps children move, with a focus on walking, balance, strength, and coordination.
- Arizona children under 3 can be referred to the Arizona Early Intervention Program (AzEIP) at no cost to the family.
What is the Difference Between OT, PT, and Speech Therapy?
Speech therapy focuses on communication, occupational therapy focuses on daily-life skills, and physical therapy focuses on movement. Each is led by a licensed specialist who evaluates your child and sets goals for their age and needs.
| What to compare | Speech-language therapy | Occupational therapy | Physical therapy |
|---|---|---|---|
| Primary focus | Communication, language, feeding, and swallowing | Daily activities, fine motor skills, sensory processing | Movement, strength, balance, gross motor skills |
| Who provides it | Speech-language pathologist (SLP) | Occupational therapist (OT) | Physical therapist (PT) |
| Credentials | Master’s degree, ASHA CCC-SLP, state license | Master’s or doctoral degree, NBCOT certification, state license (OTR/L) | Doctor of Physical Therapy (DPT), state license |
| Common signs your child may need it | Few words for their age, hard to understand, stuttering, coughing or gagging at meals | Trouble holding a crayon or using utensils; strong reactions to noise or textures | Late walking, frequent falls, toe walking, trouble with stairs |
| Typical session activities | Picture books, pretend play, sound games, AAC devices | Puzzles, bead stringing, therapy swings, dressing practice | Obstacle courses, balance beams, ball games |
| Example goal | Combine two words to ask for help | Button a jacket without help | Climb stairs with alternating feet |
What is Pediatric Speech Therapy?
Pediatric speech therapy is treatment from a speech-language pathologist that helps a child understand language, express themselves, speak clearly, and eat and swallow safely. The goal is functional communication: a child who can ask for what they need, say how they feel, and join a conversation.
An SLP may treat speech delay and language delay in late talkers, articulation and phonological disorders, receptive and expressive language problems, social communication, stuttering, childhood apraxia of speech, early literacy skills, and feeding problems such as dysphagia and pediatric feeding disorder. For some children, the right tools include signs, pictures, or augmentative and alternative communication (AAC) devices alongside speech.

Feeding is one place where speech therapy and OT overlap. The SLP looks at the mouth movements for chewing and swallowing, while the OT often looks at sensory reactions to food and at self-feeding with utensils.
What is Pediatric Occupational Therapy?
Pediatric occupational therapy helps children build the skills they use every day. For a child, those “occupations” are playing, learning, eating, dressing, and sleeping. An OT works on fine motor skills, self-care, handwriting, and sensory processing, which is how a child takes in and responds to touch, sound, and movement.
A child in OT might practice cutting with scissors or spend time on a swing so their body feels calm before a learning task. A simple way to separate the two motor therapies: physical therapy helps a child get across the room, and occupational therapy helps them do something useful once they get there.

What is Pediatric Physical Therapy?
Pediatric physical therapy helps children improve gross motor skills, the large movements used for crawling, walking, running, jumping, and climbing. A physical therapist builds strength, balance, endurance, and coordination.
PTs often work with children who have cerebral palsy, Down syndrome, torticollis, low muscle tone, or persistent toe walking. A PT might help a toddler take their first independent steps while an OT on the same team helps that toddler use both hands to carry a toy.

Signs Your Child May Need OT, PT, or Speech Therapy
Look for patterns over weeks, not one bad day. Use this checklist to start a conversation with your pediatrician.
| What you notice | Therapy to ask about |
|---|---|
| Few words by 18 months, or no two-word phrases by age 2 | Speech therapy |
| Speech that family struggles to understand after age 3 | Speech therapy |
| Meltdowns or hitting when not understood | Speech therapy, often with OT |
| Coughing, gagging, or refusing many food textures | Speech therapy or OT |
| Trouble holding a crayon, using a spoon, or managing buttons | Occupational therapy |
| Distress with noise, clothing tags, messy play, or haircuts | Occupational therapy |
| Not walking by 18 months, or frequent tripping | Physical therapy |
| Trouble with stairs, jumping, or keeping up with other kids | Physical therapy |
| Losing skills your child used to have | Call your pediatrician right away |

Developmental Milestones by Age
According to the CDC, developmental milestones are things most children (75% or more) can do by a certain age. This table pulls a few from the CDC’s milestone checklists.
| Age | Communication | Movement and daily skills |
|---|---|---|
| 12 months | Waves bye-bye; calls a parent “mama,” “dada,” or another special name | Pulls up to stand; picks up small things between thumb and pointer finger |
| 18 months | Tries to say three or more words besides “mama” or “dada”; follows one-step directions without gestures | Walks without holding on; tries to use a spoon |
| 2 years | Says two words together, like “more milk” | Kicks a ball; runs (full 2-year checklist) |
| 3 years | Has conversations with at least two back-and-forth exchanges | Uses a fork; puts on some clothes |
| 4 years | Says sentences with four or more words | Catches a large ball most of the time |
| 5 years | Tells a story with at least two events | Hops on one foot; buttons some buttons |
ASHA also publishes communication and feeding milestones from birth to 5, and the free CDC Milestone Tracker app makes tracking easy.
Can a Child Get OT and Speech Therapy at the Same Time?
Yes. Many children receive two or all three therapies, and their therapists coordinate goals. Some clinics offer co-treatment, with two therapists in one session.
Picture a 4-year-old with autism spectrum disorder. The SLP builds requesting and conversation skills. The OT helps the child manage sensory overload that makes it hard to focus. In a co-treatment, the OT keeps the child regulated on a swing while the SLP prompts them to say “more” or “stop.”
That is the heart of speech therapy vs. occupational therapy for autism: the SLP targets communication, the OT targets regulation and daily skills, and together they cover more ground. Combined care is also common with Down syndrome, cerebral palsy, and ADHD. Explore Theracare’s integrated therapies or our article on mental health and autism in early childhood.
Who Provides Each Therapy? Credentials Explained
The letters after a therapist’s name show their training. Assistants (SLPA, COTA, PTA) can run sessions under a licensed therapist’s supervision, so ask who will do the evaluation and who will lead weekly visits.
| Credential | What it means |
|---|---|
| CCC-SLP | Master’s degree, clinical fellowship, national exam, and ASHA’s Certificate of Clinical Competence |
| OTR/L | Master’s or doctoral degree, NBCOT national exam, and state license |
| DPT | Doctor of Physical Therapy degree, national exam, and state license |
What Happens at a Pediatric Therapy Evaluation?
A pediatric evaluation is mostly play. The therapist watches your child, talks with you about history and concerns, and may use standardized tests suited to your child’s age. They look at what your child does well, where difficulties show up, how those challenges affect daily life, and what goals matter to your family.
Take a 3-year-old who understands everyday directions but uses only a handful of words and gets upset when adults don’t understand. The SLP checks receptive and expressive language, speech sounds, and play. Goals might include a bigger functional vocabulary, two-word phrases, asking for help, and taking turns, all practiced through toys, books, songs, and routines so skills carry over to real life.

How to Get Started: Referral Paths in Arizona
| Path | Ages | Cost | Plan you receive |
|---|---|---|---|
| Pediatrician referral to a private clinic | Any age | Insurance, DDD, ESA, or private pay | Clinic treatment plan |
| Arizona Early Intervention Program (AzEIP) | Birth to 3 | No cost to the family | Individualized Family Service Plan (IFSP) |
| Local public school district | 3 and up | Free for eligible students | Individualized Education Program (IEP) |
AzEIP runs under Part C of the Individuals with Disabilities Education Act (IDEA), and parents can refer their own child. A service coordinator typically calls within two days, and eligible families receive an IFSP within 45 days of referral.
Insurance, Cost, and Funding
Theracare accepts most insurance plans and is contracted with Arizona’s Division of Developmental Disabilities (DDD) and the Empowerment Scholarship Account (ESA) program.
To use insurance, ask your child’s primary care physician for a prescription for services. Whether speech therapy is covered by insurance or Medicaid (AHCCCS) depends on your plan, so call to confirm before your first visit. See full insurance and funding details.
Clinic, Home, School, or Teletherapy?
| Setting | Often a good fit for | What to know |
|---|---|---|
| Clinic | Children who benefit from sensory equipment or co-treatment | Theracare’s Mesa clinic has therapy swings, a climbing wall, a sensory station, and a life-skills kitchen |
| In-home pediatric therapy | Toddlers and children working on daily routines | Therapists coach parents where the child eats, plays, and sleeps |
| School-based | School-age children with classroom goals | Theracare therapists work in schools across the Valley |
| Teletherapy | Families with travel or scheduling barriers | ASHA recognizes telepractice for many speech services; ask if it fits your child |
Common Worries Parents Have
- Will my child outgrow it?: Some late talkers and late walkers catch up, but no one can reliably predict which ones will. The CDC’s “Learn the Signs. Act Early.” program encourages parents to act as soon as they have a concern. An evaluation gives you either peace of mind or an early start.
- Is my child too young?: Rarely. AzEIP serves babies from birth, and therapists regularly treat infants for feeding problems, torticollis, and motor delays.
- How long does therapy take?: It depends on your child’s needs, goals, and attendance. Therapists recheck progress regularly, and AzEIP reviews each IFSP at least every six months.
- Can we do therapy at home?: Yes. In-home sessions are available, and practice between sessions matters.
How You Can Support Progress at Home
- Narrate routines (“Now we’re putting on your shoes”) to build vocabulary.
- Add a word to what your child says: “juice” becomes “more juice, please.”
- Make time for stairs, playgrounds, and ball games.
- Let your child help with simple self-care, even when it takes longer.
Frequently Asked Questions
1. What is the difference between OT and speech therapy for a toddler?
Speech therapy helps a toddler understand and use words and eat safely. Occupational therapy helps with hand skills, self-feeding, play, and sensory reactions. A toddler who struggles in both areas may benefit from both.
2. How do I know if my child needs speech therapy?
Common signs include fewer than three words besides “mama” or “dada” by 18 months, no two-word phrases by age 2, speech family can’t understand after age 3, lasting stuttering, or frustration from not being understood. An SLP evaluation will tell you whether therapy would help.
3. At what age should a child start speech therapy?
There is no minimum age. SLPs treat infants with feeding problems and toddlers with early language delays. If you have a concern, ask for an evaluation now.
4. What is the difference between physical therapy and occupational therapy for kids?
Physical therapy builds large movements like walking, running, jumping, and balance. Occupational therapy applies movement to daily tasks such as dressing, eating, and handwriting, and also addresses sensory processing.
5. Is speech therapy covered by insurance or Medicaid in Arizona?
It depends on your plan. Many private plans cover pediatric speech therapy with a physician’s prescription, and families may also use DDD or ESA funding. Children under 3 who qualify for AzEIP receive services at no cost.
