Is Your Baby Always Looking One Way? Here’s Why: Understanding Torticollis and Plagiocephaly

Have you noticed your baby always tilting their head to one side, or seeming to look in the same direction most of the time?

If so, they might have a very common condition called torticollis.

As paediatric physiotherapists, we see this often in young babies — and the good news is that with early support, it can be treated really effectively.

What Is Torticollis?

Torticollis happens when the muscles on one side of your baby’s neck are a little tighter or shorter than the other side.

This can cause your baby’s head to:

  • Tilt toward the tight side

  • Turn their face toward the opposite side

There are two common types:

  • Left-sided torticollis: head tilts left, face turns right

  • Right-sided torticollis: head tilts right, face turns left

It can happen in both boys and girls and is often noticed within the first few weeks or months.

What Causes It?

Sometimes the exact cause isn’t clear, but a few things can make torticollis more likely, such as:

  • Limited space in the womb (for example, breech position or twins)

  • A difficult or assisted delivery (forceps or vacuum birth)

  • Muscle strain or positioning during birth or early newborn life

What Are the Signs?

You might notice your baby:

  • Tilts their head to one side most of the time

  • Prefers looking in one direction

  • Finds feeding easier on one side

  • Gets upset when you try to gently reposition their head

  • Seems frustrated when they can’t turn fully

If any of these sound familiar, it’s a great idea to chat with your paediatric physiotherapist or GP.

How Physiotherapy Can Help

Physiotherapy is the first and most effective treatment for torticollis.

We focus on:

  • Gently stretching the tight neck muscles

  • Encouraging movement and strength on the other side

  • Helping your baby develop more even head control and symmetry

This is important not only for neck movement, but also for preventing a flat head.

The Link Between Torticollis and Flat Head (Plagiocephaly)

Babies with torticollis often prefer resting with their head turned the same way.

Over time, this can lead to extra pressure on one area of the skull, which may cause plagiocephaly — a flattening on one side of the head.

By improving your baby’s ability to turn and move their head freely, we can support healthier, more even head shape as they grow.

What Might a Home Program Include?

Your physio will give you simple strategies that fit easily into everyday routines like tummy time, nappy changes, feeding, and play.

Gentle Stretching and Positioning

  • For left-sided torticollis, we encourage turning the head left and tilting right

  • For right-sided torticollis, we encourage turning right and tilting left

These are always done gently, often during play or cuddles.

Time Off the Back of the Head

Spending less time lying flat on the back is really helpful for both torticollis and plagiocephaly.

Great options include:

  • Tummy time

  • Skin-to-skin time on your chest

  • Side-lying play

  • Sitting supported on your lap

  • Babywearing or being held upright

Basically — any time your baby is off their back helps build strength and reduce pressure on the skull.

Everyday Handling Tips

A few small changes can make a big difference:

  • Place toys or your face on the side your baby avoids turning toward

  • Adjust feeding positions to encourage looking both ways

  • Change the way your baby lies on the play mat

  • Limit time in car seats, bouncers, or swings (aim for no more than 15–20 minutes at a time when possible)

These simple strategies help your baby move more freely and allow their head shape to develop evenly.

The Bottom Line

Torticollis is very common, and with early, consistent physiotherapy, most babies improve really well.

Early support helps:

  • Improve neck movement

  • Encourage symmetrical development

  • Reduce the risk of ongoing flat head shaping

If you’ve noticed your baby has a head tilt or turning preference, reaching out for an assessment is a great next step.

Early help makes a big difference — and you’re doing the right thing by noticing it.
