When Does My Baby Need Physical Therapy?
The short answer
Pediatric physical therapy may be recommended if your baby has delays in gross motor milestones (rolling, sitting, crawling, walking), torticollis, low or high muscle tone, or orthopedic conditions. PT helps babies develop strength, coordination, and movement patterns. Early intervention is key - the sooner therapy starts, the better the outcomes. Your pediatrician can provide a referral based on developmental screening.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
Physical therapy at this age is most commonly for torticollis (head preference to one side) or for premature babies who may have low muscle tone. A pediatric PT uses gentle stretches, positioning techniques, and parent education. Sessions often focus on teaching you exercises to do at home daily for the best results.
PT may be recommended if your baby is not meeting rolling milestones, has persistent torticollis, or shows low or high muscle tone that affects movement. Therapy at this age focuses on building core strength, achieving rolling, and preparing for sitting. The therapist will teach you play-based activities to support development at home.
If your baby is not sitting independently by 9 months or not showing interest in crawling or pulling to stand, PT may help. The therapist assesses your baby's movement patterns and creates a plan to address specific areas of delay. Sessions are play-based and should feel like fun for your baby.
PT at this age often focuses on walking, balance, and coordination. If your toddler is not walking by 18 months or has an unusual walking pattern, a referral may be warranted. Children with conditions like Down syndrome, cerebral palsy, or other developmental differences benefit greatly from ongoing physical therapy.
Physical therapy for older toddlers may address running, jumping, climbing, and overall coordination. Children who are clumsy, frequently fall, or have difficulty with physical activities compared to peers may benefit from PT. The therapist works on building confidence along with physical skills.
What Should You Do?
When to take action
- Your baby is meeting milestones within the normal range (there is a wide range of normal)
- Your baby has been referred for PT and is making progress with therapy exercises
- Minor variations in development that resolve with simple home activities
- Your baby seems behind peers in physical milestones like sitting, crawling, or walking
- Your baby strongly favors one side of the body or has asymmetric movement
- You have concerns about your baby's muscle tone (too floppy or too stiff)
- Your baby loses previously acquired motor skills (regression)
- Your baby has sudden weakness, inability to move a limb, or extreme stiffness that is new

When Does My Baby Need Occupational Therapy?
Pediatric occupational therapy helps babies develop fine motor skills (hand use, grasping, reaching), feeding skills, sensory processing, and daily living activities. OT may be recommended if your baby has difficulty with feeding, limited hand use, sensory sensitivities, or delays in fine motor milestones. OT focuses on helping your baby participate in the everyday "occupations" of childhood: eating, playing, and exploring.
When Does My Baby Need Speech Therapy?
Speech-language therapy may be recommended if your baby is not babbling by 9 months, not using any words by 15-18 months, or has fewer than 50 words and no two-word phrases by age 2. A speech-language pathologist (SLP) works on both understanding language (receptive) and producing language (expressive), as well as feeding and swallowing difficulties. Early intervention for speech delays leads to significantly better outcomes.
When Should My Baby See a Developmental Pediatrician?
A developmental pediatrician specializes in diagnosing and managing developmental delays, autism spectrum disorder, ADHD, learning disabilities, and behavioral concerns in children. Referral is typically recommended when a baby has delays in multiple areas, when the cause of delays is unclear, or when a complex diagnosis like autism is suspected. Wait times can be long, so request a referral early if you have concerns.
My Baby Tilts Their Head to One Side - Is It Torticollis?
A persistent head tilt in a baby is most commonly caused by congenital muscular torticollis (a tight sternocleidomastoid muscle), which is treatable with physical therapy. However, other causes include eye problems (the baby tilts to compensate for misaligned eyes), hearing issues, neurological conditions, Sandifer syndrome (reflux-related posturing), or structural cervical spine issues. Any persistent head tilt should be evaluated to identify the cause.
My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
