If your baby has been diagnosed with or you suspect tilts their head to one side - is it torticollis, here is what the evidence says.
The short answer
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.
Key takeaways
- 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.
- Usually normal when: A mild head preference in a newborn that improves with repositioning and tummy time
- Call your doctor if: A sudden new head tilt with fever, neck stiffness, or refusal to move the neck (possible neck infection or meningitis)
- Varies by age — see the age-by-age breakdown below
“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, NIH, Mayo Clinic guidelines, 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. At 0-3 months, congenital muscular torticollis (CMT) is the most common cause of head tilt in young babies. It may be related to positioning in the womb or birth. You may feel a small firm lump in the neck muscle. CMT responds very well to physical therapy and stretching exercises when started early. The earlier treatment begins, the faster the resolution. It is generally considered normal when a mild head preference in a newborn that improves with repositioning and tummy time. However, you should contact your pediatrician promptly if a sudden new head tilt with fever, neck stiffness, or refusal to move the neck (possible neck infection or meningitis).
Normal vs. Concerning
By Age
What to expect by age
0-3 months
Congenital muscular torticollis (CMT) is the most common cause of head tilt in young babies. It may be related to positioning in the womb or birth. You may feel a small firm lump in the neck muscle. CMT responds very well to physical therapy and stretching exercises when started early. The earlier treatment begins, the faster the resolution.
3-6 months
If torticollis has not been addressed, you may notice associated plagiocephaly (flat spot on the head) from the baby consistently lying on one side. Physical therapy with specific stretching and positioning exercises is the primary treatment. Your pediatrician may also recommend extra tummy time on the non-preferred side.
6-12 months
If a head tilt develops after the newborn period (acquired torticollis), other causes should be considered. A head tilt that suddenly appears with fever could indicate a neck infection (retropharyngeal abscess). A head tilt associated with eye issues could be ocular torticollis. Your pediatrician will evaluate based on the timing and associated symptoms.
12-24 months
A new head tilt in a toddler warrants evaluation. Causes include inner ear infection, eye alignment problems, trauma, and rarely, posterior fossa brain tumors (which may cause head tilt along with vomiting and balance problems). A head tilt that comes and goes and is associated with arching may be Sandifer syndrome related to reflux.
2-3 years
A persistent or new head tilt in an older toddler should be evaluated. If the head tilt is accompanied by changes in walking, balance, vision, or new vomiting, prompt evaluation is important. Atlantoaxial rotatory subluxation (cervical spine issue) can cause acute torticollis in older children, sometimes following a minor injury or throat infection.
What to Tell Your Pediatrician
- Describe when you first noticed tilts their head to one side - is it torticollis and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby consistently tilts their head to one side despite repositioning efforts.
- Mention if you notice a flat spot developing on one side of your baby's head.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- A mild head preference in a newborn that improves with repositioning and tummy time
- Diagnosed congenital muscular torticollis that is improving with physical therapy
- A brief head tilt related to trying to see or hear something that resolves quickly
- Your baby consistently tilts their head to one side despite repositioning efforts
- You notice a flat spot developing on one side of your baby's head
- A head tilt is present but your pediatrician has not yet evaluated it
- A sudden new head tilt with fever, neck stiffness, or refusal to move the neck (possible neck infection or meningitis)
- A head tilt accompanied by vomiting, balance problems, eye movement abnormalities, or changes in behavior (needs prompt neurological evaluation)
What You Can Do at Home
- Keep track of when you notice tilts their head to one side - is it torticollis — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that a mild head preference in a newborn that improves with repositioning and tummy time — this is generally within the range of normal.
- At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if a sudden new head tilt with fever, neck stiffness, or refusal to move the neck (possible neck infection or meningitis).
Related Conditions
Treatment for Congenital Muscular Torticollis
Congenital muscular torticollis (CMT) is treated primarily with physical therapy, including gentle stretching exercises, positioning strategies, and strengthening activities. When started within the first 3 months of life, over 90% of cases resolve with physical therapy alone within 6-12 months. Treatment includes specific stretches performed during diaper changes and play, repositioning techniques, and increased tummy time on the non-preferred side. Surgery is rarely needed (less than 5% of cases).
Does My Baby Need a Helmet for Flat Head?
Helmet therapy (cranial orthosis) may be recommended for moderate to severe positional plagiocephaly that has not improved with repositioning techniques by age 4-6 months. Helmets work by gently guiding skull growth and are most effective when started between 4-6 months of age, when head growth is most rapid. Mild cases often improve on their own with repositioning and tummy time. The decision depends on severity, age, and whether conservative measures have been tried.
When Does My Baby Need Physical Therapy?
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.
Eye Alignment Issues in Infants
Eye alignment issues (strabismus) in infants can involve one eye turning inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia). Intermittent misalignment in newborns under 3-4 months is very common and usually resolves as eye muscles strengthen. Constant misalignment at any age, or any misalignment persisting after 4 months, should be evaluated by a pediatric ophthalmologist. Many parents also mistake pseudostrabismus (the appearance of crossed eyes caused by a wide nasal bridge) for true misalignment.

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.
