Torticollis and Flat Head: When to See a PT
Your baby always seems to look in the same direction. Maybe you noticed a flat spot on the back of their head during bath time, or a relative pointed out a little head tilt in photos. Torticollis and flat head often show up together, and both are common.
The important part is timing. Torticollis responds very well to physical therapy, and the earlier it starts, the faster and more completely it tends to resolve. Here is what to look for and what to do at each age.
What Torticollis and a Flat Spot Look Like
Head Tilt in Babies: The Signs of Torticollis
Torticollis means a tight neck muscle is pulling your baby's head to one side. You might notice that your baby:
Tips one ear toward their shoulder while their face turns the other way
Almost always turns to the same side, whether sleeping, feeding, or playing
Seems to have a harder time turning their head in one direction
Some babies are born with it, but it most often develops after birth. It can come from how a baby was positioned in the womb or from lots of time spent on their back or in car seats and swings. As many as 1 in 6 newborns have it.
Plagiocephaly: The Flat Spot
Positional plagiocephaly is the medical name for a flat spot on a baby's head. It happens when a young baby's soft skull rests in the same position again and again. Most parents notice it around 6 to 8 weeks old.
Why They Show Up Together
A baby with a tight neck muscle keeps resting on the same spot, so that spot flattens. In many babies, the flat spot is actually the first clue. It often sits behind the ear on the side your baby prefers to turn.
Why Timing Matters So Much
What the Research Shows
Research reviewed for the American Physical Therapy Association's torticollis guideline found a clear pattern based on when physical therapy began:
Before 1 month: about 98% reached typical neck movement, with roughly 1.5 months of PT
1 to 3 months: about 89%, with roughly 6 months of PT
3 to 6 months: about 62%, with roughly 7 months of PT
After 6 months: under 20%, with roughly 10 months of PT
That last line is hard to read. It does not mean an older baby cannot improve. It means the muscle gets harder to stretch as time passes, so treatment takes longer and works less completely. The takeaway is simple: if you notice a tilt, bring it up now instead of waiting to see if it sorts itself out.
The Window for Head Shape
Head shape has its own clock. A baby's skull is only soft and moldable for a limited time, and repositioning works best before about 4 months. Head flattening usually stops getting worse once babies gain head control, typically around 3 months.
What to Do at Each Age
Newborn to 2 Months
Always place your baby on their back to sleep, and alternate which way their head faces from one sleep to the next.
Offer supervised tummy time while your baby is awake. Our guide on how much tummy time your baby needs breaks it down by age.
If you notice a tilt or a strong side preference, mention it to your pediatrician right away rather than waiting for the next checkup.
2 to 4 Months
This is when many flat spots get noticed. Keep up the tummy time and repositioning, and limit long stretches in car seats, swings, and bouncers outside of travel. If your baby has a head tilt, this is a good time to start PT.
4 to 6 Months: The Helmet for Flat Head Question
If a flat spot has not improved with repositioning, or it is moderate to severe, your doctor may bring up a helmet. The ideal time to be assessed is generally between 4 and 6 months. A few things to know:
Helmets are prescribed by a doctor and fitted by an orthotist, not a physical therapist.
They are usually worn about 23 hours a day for several months.
Helmets round the head faster, but on average, babies with and without helmets end up with similar results after a couple of years.
That last point is worth a real conversation with your pediatrician before deciding.
6 Months and Older
Once babies sit on their own, a flat spot usually stops getting worse and tends to improve with growth. Torticollis at this age still deserves attention, and PT can still help. A head tilt that shows up for the first time at 6 months or later should be checked by your pediatrician, since late onset can have other causes.
What PT Actually Involves
Physical Therapy for Torticollis, Step by Step
A pediatric physical therapist starts by watching how your baby moves in different positions and measuring how far their head turns and tilts. From there, treatment usually includes:
Gentle stretches for the tight side of the neck
Strengthening through play, so your baby actively turns both ways
Positioning ideas for sleep, feeding, carrying, and play
A home program you do between visits
The home program matters a lot. Stretching more often is linked to better results, so you will leave each visit knowing exactly what to practice. Our guide to pediatric physical therapy explains more about what PT looks like for young kids.
Depending on your baby's needs, Illinois Early Intervention may be another route to therapy at home. Our post on what early intervention is and who qualifies covers the basics.
Why Tummy Time Still Matters
Tummy time takes pressure off the back of the head and builds the neck and shoulder strength babies need for rolling, sitting, and crawling. PT often uses it as part of treatment, with tweaks to encourage turning toward the harder side. Tight necks can affect those later skills, so our post on gross motor milestones by age is a helpful reference.
Getting Help for Torticollis and Flat Head
When to Call Your Pediatrician First
Your pediatrician should always be part of the picture, and some signs call for a doctor visit before anything else:
A head tilt that appears suddenly, or after an illness or injury
A tilt that starts at 6 months or older
Eye concerns, like crossed eyes or trouble following a toy
A lump in the neck, or a head shape that looks unusual in ways beyond a flat spot
Your doctor can also rule out craniosynostosis, a less common condition where skull bones fuse too early.
