Does My Baby Need Physical Therapy?
The short answer
Pediatric physical therapy (PT) helps babies and toddlers who have delays or difficulties with gross motor skills like rolling, sitting, crawling, standing, and walking. PT is recommended when a child is significantly behind on motor milestones, has muscle tone issues (too stiff or too floppy), shows asymmetric movement, or has a diagnosed condition affecting movement. Early intervention PT is free or low-cost in most states for children under 3.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
PT may be recommended if your baby has torticollis (head turning preference), difficulty with tummy time, low muscle tone, or a known medical condition like Down syndrome or prematurity. Early PT at this age focuses on positioning, stretching, and encouraging movement.
PT may be helpful if your baby is not rolling, has difficulty with sitting, shows significant head lag, or has asymmetric movement patterns. A PT can assess whether your baby's motor development is on track and provide exercises to support progress.
If your baby is not sitting independently, not crawling or moving toward mobility, or not pulling to stand by the later end of this range, PT evaluation is recommended. PT can help your child build the strength and coordination needed for walking.
PT is commonly recommended if your child is not walking by 18 months, walks with an unusual gait pattern, has persistent toe walking, or shows balance and coordination difficulties significantly behind peers.
What Should You Do?
When to take action
- Your baby is meeting motor milestones within the expected range.
- Your baby moves symmetrically (uses both sides equally).
- Muscle tone feels normal (not too stiff or too floppy).
- Your pediatrician is not concerned about motor development.
- Your baby seems behind on motor milestones compared to peers.
- Your baby strongly prefers one side of the body.
- Your baby seems unusually stiff or floppy.
- You have a family history of motor delays.
- Your baby has lost motor skills they previously had.
- Your baby is not sitting by 9 months.
- Your baby is not walking by 18 months.
- Your baby has sudden changes in movement or muscle tone.

Does My Baby Need Occupational Therapy?
Pediatric occupational therapy (OT) helps babies and toddlers develop fine motor skills (hand use, grasping, manipulation), sensory processing, feeding skills, and self-care abilities. OT may be recommended if your child has difficulty with hand coordination, avoids or seeks sensory input excessively, struggles with feeding textures, or has delays in self-care skills like using utensils. Like PT, early intervention OT is available at low or no cost for children under 3.
Does My Baby Need to See an Orthopedist?
A pediatric orthopedist specializes in bone, joint, and muscle conditions in children. Your pediatrician may recommend an orthopedic referral if your baby or toddler has a hip click or asymmetry, persistent foot deformity, abnormal leg alignment, limping, joint swelling, or a bone/skeletal concern. Many childhood orthopedic conditions are normal variations that resolve on their own, but some require treatment that works best when started early.
My Baby Isn't Crawling Yet
The age range for crawling is huge - some babies crawl as early as 6 months, others not until 10-11 months, and some skip crawling entirely and go straight to walking. What matters most is that your baby has some form of independent mobility (scooting, rolling, army crawling) by around 12 months and is exploring their environment.
My Baby Seems to Use One Side More Than the Other
Babies should use both sides of their body fairly equally during the first 18 months of life. While slight preferences can be normal, a consistent pattern of favoring one side - using one arm much more than the other, crawling with one leg dragging, or turning the head predominantly one way - should always be discussed with your pediatrician. Early identification of asymmetry leads to the best outcomes.
My Baby Only Army Crawls
Army crawling (also called commando crawling) is a completely valid and normal way for babies to move. Many babies army crawl for weeks or even months before transitioning to hands-and-knees crawling, and some skip hands-and-knees crawling entirely. What matters is that your baby is independently mobile and exploring their environment.
One Side of My Baby's Body Moves Differently
Babies should generally use both sides of their body equally. If one side consistently moves differently, is weaker, stiffer, or less coordinated, this warrants evaluation. Asymmetric movement can indicate hemiplegia (cerebral palsy affecting one side), brachial plexus injury, or other neurological conditions that benefit from early therapy.
