You've probably noticed it in small ways at first. Your baby always seems to look to the same side. Their head tilts slightly in one direction. Maybe breastfeeding is easy on one side and a battle on the other. Or you've noticed a flat spot developing on the back of their head.
If any of this sounds familiar, your baby might have torticollis. And before you spiral into worry, here's the most important thing to know: torticollis is incredibly common, very treatable, and one of the top reasons babies start working with a pediatric physical therapist.
What Is Torticollis?
Torticollis (sometimes called "wry neck") is a condition where a baby's neck muscles are tighter on one side than the other. This causes the head to tilt toward the tight side and rotate toward the opposite side. The muscle involved is the sternocleidomastoid (SCM), a large muscle that runs along each side of the neck.
The most common type in babies is congenital muscular torticollis (CMT). "Congenital" means it's present at birth or develops within the first few months. It's estimated to affect anywhere from 1 in 60 to 1 in 250 newborns, making it one of the most common musculoskeletal conditions in infants.
Signs of Torticollis in Babies
Torticollis can be subtle, especially in the early weeks. Here's what to watch for:
- Head tilt. Your baby's head consistently tilts to one side, with their ear moving toward that shoulder.
- Preferred direction of turning. They strongly prefer looking one way and resist turning the other direction.
- Feeding difficulty on one side. Nursing or bottle feeding is notably harder on one side because turning their head that way is uncomfortable.
- Flat spot on the head. Because your baby keeps their head in one position, the skull can flatten on one side (plagiocephaly). This is often the first thing parents or pediatricians notice.
- A small lump in the neck muscle. Some babies develop a small, firm area in the SCM muscle. This is called a sternocleidomastoid tumor (it's not cancerous) and it's just the tight, bundled muscle fibers.
- Asymmetric movement. You might notice your baby reaches more with one arm, rolls only to one side, or seems to "prefer" one half of their body.
What Causes Torticollis?
There are a few common causes:
Positioning in the womb. The most common cause. If a baby was cramped or positioned with their head turned to one side for an extended period, the neck muscles can tighten. This is especially common in breech babies, multiple pregnancies, and first pregnancies where the uterus hasn't been stretched before.
Birth-related factors. Difficult deliveries, especially those involving vacuum or forceps assistance, can sometimes contribute to muscle tightness in the neck.
Postnatal positioning habits. Babies who spend a lot of time in one position (always placed in the crib the same way, spending long stretches in a car seat or swing) can develop a positional preference that leads to tightness over time.
Why Early Treatment Matters
Torticollis responds really well to physical therapy, especially when it's caught early. Research consistently shows that babies who start PT before 3 months of age have faster recovery times and better outcomes than those who start later.
Without treatment, torticollis can lead to:
- Plagiocephaly (flat head) that may require a corrective helmet
- Asymmetric development, where one side of the body becomes stronger or more coordinated than the other
- Delayed motor milestones like rolling, sitting, and crawling
- Potential vision issues if the head position limits their visual field on one side
The good news: with consistent PT and a home stretching program, most babies with torticollis resolve completely within a few months.
How Pediatric PT Treats Torticollis
A pediatric physical therapist will evaluate your baby's neck range of motion, head shape, overall strength, and motor development. From there, treatment typically includes:
Gentle stretching. Your PT will teach you specific stretches to lengthen the tight SCM muscle. These are done gently and often during everyday activities like diaper changes, feeding, and play time. The stretches are not painful for your baby, though they might fuss because they're being moved into a position they don't prefer.
Strengthening exercises. Building strength in the weaker side of the neck and trunk. This often involves strategically positioning toys, using tummy time positions, and encouraging your baby to look and reach toward their non-preferred side.
Positioning strategies. Your PT will help you rethink how you hold, feed, carry, and lay down your baby to naturally encourage them to turn their head in the direction they've been avoiding.
Tummy time guidance. Tummy time is one of the most important tools for treating torticollis. It strengthens neck and trunk muscles and gives your baby opportunities to practice turning their head both ways. Your PT will show you how to modify tummy time if your baby resists it.
Environmental setup. Small changes, like which side of the crib you approach from, where you place a mobile, or which arm you carry your baby on, can make a significant difference over time.
Stretches You Can Start at Home
While these don't replace a professional evaluation, here are a few things you can start doing today:
- Encourage looking both ways. Position yourself, toys, and visual stimulation on your baby's non-preferred side during play time.
- Switch sides during feeding. Alternate which arm you use to hold your baby during bottle feeding. If breastfeeding, work on getting a good latch on the more difficult side.
- Vary crib positioning. Alternate which end of the crib you place your baby's head so they're motivated to turn toward activity in the room.
- Do plenty of tummy time. Start with short sessions several times a day and build up. Position a toy or your face on the non-preferred side to encourage turning.
- Side-lying play. Lay your baby on their side (the non-preferred side) and play with them face to face. This naturally stretches the tight muscle.
When to See a Pediatric PT
If you notice any of the signs described above, there's no reason to wait. A pediatric PT can evaluate your baby and give you a clear answer about whether torticollis is present and what to do about it.
At Coral Care, our pediatric PTs come to your home for evaluations and treatment sessions. This means your baby gets worked with in their natural environment, and you learn the stretching and positioning techniques right where you'll actually be doing them every day.
If your baby seems to prefer one side, has a flat spot developing, or if feeding is consistently easier on one side than the other, schedule a free consultation with a Coral Care PT. Early intervention makes a real difference with torticollis, and most families see significant progress within the first few weeks.
