Infant Torticollis (Tight Neck Muscle)
Infant torticollis is a tightening of one of the neck muscles that makes a baby tilt their head to one side and turn it to the other. It is common, usually painless, and responds very well to stretching and positioning, especially when caught early.

Quick Answer
Infant torticollis (congenital muscular torticollis) is a tight or shortened sternocleidomastoid muscle on one side of the neck, which makes a baby hold the head tilted to one side and turned to the other. It is treated with gentle stretching, positioning, and tummy time, and most babies recover fully with early physical therapy.
Key Takeaways
- Torticollis is a **tight neck muscle** that makes a baby tilt and turn the head.
- It is **common and usually painless**, and often noticed in the first months.
- It responds very well to **stretching, positioning, and tummy time**.
- **Early physical therapy** leads to full recovery in most babies.
What Causes Infant Torticollis?
The most common form, congenital muscular torticollis, is caused by tightness in the sternocleidomastoid muscle, often from the baby's position in the womb or during birth. It is sometimes linked with a flattened head (plagiocephaly) because the baby rests on one side. Less commonly, torticollis can have other causes, which a doctor checks for.
Signs and Treatment
Parents may notice the baby consistently tilting the head one way, turning it more easily to one side, a preference for looking in one direction, or a small soft lump in the neck muscle. Treatment is gentle and effective: a physical therapist teaches stretching and positioning, and plenty of supervised tummy time strengthens the neck. Most babies improve within months when treatment starts early.
How Home Care Helps
Much of the treatment for torticollis is a daily home program of stretches and positioning. Focus Family Care provides pediatric home care that helps families carry out the therapist's plan consistently, supports positioning and tummy time, and watches the baby's progress. For medically complex infants, a registered nurse coordinates the wider care plan.

Frequently Asked Questions
Will my baby's torticollis go away?
Most babies recover fully, especially with early stretching, positioning, and physical therapy. The earlier treatment begins, the better and faster the results usually are.
Is torticollis painful for my baby?
Congenital muscular torticollis is usually not painful. Gentle stretching may be briefly uncomfortable, but it is well tolerated. Tell your doctor if your baby seems to be in pain.
What is the connection between torticollis and a flat head?
A baby with torticollis often rests on the same spot, which can flatten one side of the head (plagiocephaly). Treating the torticollis and varying head position helps prevent and improve flattening.
