Physical Therapy for Babies and Toddlers
Physical therapy for a child under three focuses on how they move: holding their head up, rolling, sitting, crawling, walking, and using both sides of their body. The most common reason for referral is a head tilt with a preference for looking one way, which is congenital muscular torticollis and responds well to early treatment. Other common reasons are delayed motor milestones, low muscle tone, and a strong one-sided preference. Sessions usually take place at home and look like play on the floor, with the therapist teaching you positions, handling, and activities to use through the day. A baby practices during their waking hours, not during a weekly appointment.
What physical therapy does at this age
Head control and neck movement, including torticollis, which is the most common referral. → Torticollis in infants
Rolling, sitting, crawling, standing, and walking — the sequence, and what to do when it stalls. → Delayed motor milestones
Muscle tone, whether low or high, and how it affects movement. → Hypotonia
Using both sides of the body, and addressing a strong one-sided preference.
Head shape, which is closely tied to neck movement.
Tummy time, which is more often a therapy question than parents realize — refusal is common and usually addressable.
Equipment and positioning where needed.
Signs it might help
- A consistent head tilt, or a strong preference for looking one way
- A flat spot developing on one side of the head
- Persistent head lag after around four months
- Not rolling either way by around 6 months
- Not sitting without support by around 9 months
- Not walking by around 18 months
- Very stiff, or very floppy
- Strongly prefers one hand or one side before around 18 months
- Refuses tummy time consistently
- Toe walking that persists → Toe walking
- Loss of a motor skill previously held — this needs prompt medical evaluation
What a session looks like
Where does it happen?
At home, on the floor. Very little of it will look like treatment.
What does the therapist actually do?
They handle your baby — positioning, guiding movement, and supporting a position so your child can do slightly more than they could alone.
They will use toys and your voice to motivate movement, because a baby moves toward something they want rather than on request. And they will show you, then watch you do it — handling is a skill, and it is learned by doing it with someone correcting you.
What am I supposed to be doing?
Changing how the day is arranged. How you carry, how you lay them down, which side you feed from, which end of the crib you approach from.
Why so much of it happens through you
A baby spends their waking hours moving or not moving. That is the intervention.
Positioning across the day matters more than any single exercise — which side you carry on, which way they face in the crib, how much floor time they get, and how much time is spent in seats and swings.
Little and often beats long and occasional. Ten short opportunities across a day outperform one long session, and only you can provide those.
What is different about this age
The nervous system is highly responsive, and early intervention during this period is more effective than the same intervention later.
Skills build on each other. A baby who cannot get onto their tummy comfortably misses the strength that leads to crawling, which affects what comes after.
Positioning has outsized effects — on the head, the neck, and on which movements get practiced at all.
How to get started
Do I need a referral?
No. Under three, early intervention is free, needs no referral, and a parent can self-refer. Your pediatrician can also refer.
What will it cost?
Early intervention is free. Private physical therapy is available at any age and insurance coverage varies. → Therapy costs and insurance
When milestones are late
The sequence matters more than the dates. Rolling, sitting, crawling, pulling to stand and walking build on one another, and a baby who is stuck at one step is usually missing something the previous step was supposed to build.
What a physical therapist is actually looking at is not only whether a skill is present but how it is done: whether a baby sits with a straight back or props on their hands, whether they roll both directions or only one, whether they bear weight evenly. A skill done in a compensating way is a different finding from a skill not yet present, and it points somewhere different.
Skipping crawling is not automatically a concern, and neither is bottom-shuffling. What matters is whether the child has a way to get where they want to go and whether both sides are being used. → Delayed motor milestones
Tummy time, and why it is refused
Refusal is extremely common and it is usually addressable, which is worth knowing before it becomes a daily fight.
Babies refuse tummy time for reasons that have solutions: it is hard work and they tire quickly; reflux makes it uncomfortable lying flat after a feed; a tight neck on one side makes turning to look painful; or they have simply had very little of it and it is unfamiliar.
What usually helps: short and frequent rather than long and once; on your chest or across your lap rather than on the floor; after a nap rather than after a feed; and with your face where they want to look.
It matters because tummy time builds the neck, shoulder and trunk strength that rolling, sitting and crawling depend on — and because time on the back is time the head is being flattened.
Head shape and flat spots
A flat spot is usually a positioning story, and it is closely tied to the neck. A baby who prefers looking one way rests on the same part of their head every time they are put down, and the shape follows.
That is why head shape and torticollis are assessed together: treating the flat spot without addressing why the head keeps turning the same way treats the symptom. Back to sleep remains the advice — the answer is more varied positioning while awake, not less time on the back at night. → Torticollis in infants
What progress looks like
In what your baby does on the floor, not in what they do in a session. More time tolerating tummy time, turning both ways, reaching further, moving to get something.
Progress is often quick once the right positioning is in place, and slow when the day has not changed. If nothing is shifting, the first question is usually what the twenty-three hours outside the session look like rather than what happens inside it.
Milestones are a guide rather than a schedule, and babies vary. What matters more than hitting a date is whether movement is symmetrical and whether the sequence is progressing at all.
Goals worth setting
| Goals that work | Goals that don't |
|---|---|
| Turns their head both ways to follow me Tolerates five minutes of tummy time without distress Sits without support long enough to play Pulls to stand at the sofa Uses both hands to hold a bottle Crawls across the room to get a toy | Improve head control Increase gross motor skills Improve postural stability |
Questions worth asking
- What should our day look like differently from tomorrow?
- How should I be carrying and positioning them?
- Have the hips been examined?
- What would make you refer on, and to whom?
- How will we know this is working, and by when?
Frequently asked questions
When should a baby see a physical therapist?
If they have a consistent head tilt or one-sided preference, a flat spot developing, persistent head lag after four months, are not rolling by six months or sitting by nine, seem very stiff or very floppy, or have lost a skill they previously had.
My baby has a head tilt. Is that serious?
Congenital muscular torticollis is common and responds well to physical therapy, particularly when started early. Ask for your baby's hips to be examined too, since the two are associated.
My baby hates tummy time. What do I do?
Very common, and usually addressable. Short and frequent beats long and once, and there are positions that make it easier. It is worth raising, because tummy time builds strength that later skills depend on.
Do I need a referral for infant physical therapy?
No. Early intervention under three is free in the United States, requires no doctor's referral, and a parent can refer their own child.
Will my baby catch up if I wait?
Some do. But this is the period when intervention works best, and evaluation costs nothing under three, so waiting to find out spends the window rather than saving anything.
Why is the therapist teaching me instead of treating my baby?
Because your baby practices during their waking hours, not during a weekly appointment. Positioning and handling across the day is the treatment.
What is the connection between torticollis and hip problems?
Infants with congenital muscular torticollis are at increased risk of developmental dysplasia of the hip. In one series of 292 infants with torticollis, every child who had hip dysplasia was picked up by clinical examination — so ask for the hips to be examined.
