Torticollis in babies: symptoms, treatment, and when to worry
Last updated September 3, 2026.
Torticollis in babies is when the head persistently tilts or turns to one side because a neck muscle is tight, usually the sternocleidomastoid. It is noticed in the first weeks or months, sometimes with a small lump in the muscle or a flat patch developing on one side of the head. With physiotherapy stretches, the large majority resolve completely.
What does it look like?
The head prefers one direction: tilted toward one shoulder with the chin turned the opposite way, and the baby resists or struggles to turn the other way. Look for the practical signs: always feeding on one side, always looking one direction in the cot, and a flat spot developing on the head from lying on the same side. It often follows a crowded position in the womb or a difficult birth. The tight muscle shortens, and the preference becomes a posture.
What actually helps?
- Physiotherapy early: a pediatric physio teaches gentle stretches and positioning, and earlier starts resolve faster. This is the main treatment.
- Positioning games at home: arrange the cot, toys, and your approach so the baby must turn toward the non-preferred side to see the interesting things, including you.
- Alternate feeding sides: breast and bottle positions that encourage turning the head both ways at every feed.
- Tummy time while awake: strengthens neck muscles symmetrically and relieves pressure on the flat spot. Do it several times daily, supervised.
- Safe sleep still rules: despite the flat-head worry, sleep stays flat on the back; repositioning happens during awake, supervised time.
- Follow-up for the stubborn few: persistent cases get specialist review; a tiny minority need further intervention, and most of those do well.
When is it an emergency?
Torticollis is not an emergency, but seek prompt review for a sudden new head tilt with fever, pain, or after an injury, for swelling or redness in the neck, or for a tilt accompanied by developmental concerns or unusual eye movements, since rarer causes need excluding. The routine version, a preference noticed in a well baby, deserves a timely GP or health visitor referral to physio rather than an urgent one.

Common questions
What causes torticollis in babies?
Usually a tight or shortened sternocleidomastoid, the muscle running from behind the ear to the collarbone, often after a crowded womb position or a birth that stretched the muscle, sometimes leaving a small benign lump. Less commonly, the cause sits elsewhere: vision differences, bone variations, or neurological causes, which is why assessment rather than pure home management is the right first step.
Will torticollis fix itself without treatment?
Mild preferences sometimes resolve as babies gain neck control, but established torticollis with a tight muscle generally needs active stretching, and waiting costs time: the window when physio works fastest is the early months, and untreated tightness lets the head flat spot deepen and the preference entrench. Physio referral on suspicion is the standard, not the last resort.
What exercises help a baby with torticollis?
The physio teaches the specific stretches, gentle side-bending and rotation held briefly, several times a day, plus positioning: arranging cot, toys, and your own position so the baby turns toward the non-preferred side, alternating feeding positions, and frequent supervised tummy time. The home program, done gently and consistently, is where most of the improvement happens. Never force range; stretch to the point of gentle resistance.
Will torticollis affect my baby's head shape?
It can: always lying on the same side flattens that spot (positional plagiocephaly), and the two conditions commonly arrive together. The flat spot usually improves as the torticollis resolves and the baby moves more, helped by tummy time and varied awake positioning. Head shape does not affect brain development. Persistent severe flattening gets specialist review, and helmets are reserved for selected cases.
Is it safe to reposition my baby's head during sleep?
Safe sleep rules outrank head-shape worries: babies sleep flat on their backs on a firm, clear mattress, and sleep positioners or wedges are not safe. What you can do: alternate the direction the baby lies in the cot (head at alternate ends), so the interesting things in the room encourage looking the non-preferred way, and do all active repositioning and tummy time during awake, supervised hours.
When should my baby see a physiotherapist for torticollis?
As soon as the pattern is consistent, persistent head preference, resistance to turning one way, or a lump in the neck muscle, via a GP or health visitor referral. Early physio, in the first months, resolves most cases within weeks to months. Seek faster review for a sudden new tilt with fever or after injury, neck swelling, or any eye-movement or developmental concerns alongside.
