While excessive time spent on the back is the most common cause of positional plagiocephaly, there are other crucial factors that require professional attention—especially neck-related issues.
1. Recognizing a Forced Head Preference
Early in life (during the first 8 weeks), it is normal for a baby to show a preference for turning their head to one side. This actually has neurological and survival-related advantages. However, this should be a free preference, meaning the baby is also able to turn and remain comfortable on the opposite side.
The problem arises when the preference is forced: the baby has neck difficulties (such as torticollis) and, as a result, is unable to fully turn to the other side.
This restriction in neck movement, combined with time spent on the back and insufficient activity, leads to a very clear flattening on one side of the head.
2. The Importance of Early Diagnosis
Watch closely for the following signs:
- The baby always keeps their head turned to the same side (beyond 8 weeks of age).
- The head-turning preference is excessively strong.
- The baby is unable to keep their head centered in a sustained way.
If you notice any of these signs, it is essential to seek help as early as possible.
3. The Role of the Pediatric Physical Therapist
When there is a limitation in neck movement, families cannot resolve the issue on their own.
A pediatric physical therapist – especially one trained in manual therapy for infants – is the right professional to address and release this restriction. The treatment involves slow, gentle, and respectful mobilizations that help the baby regain the ability to turn freely to both sides.
Early intervention to release the neck is a key preventive step. By freeing the neck, not only is head movement improved, but the entire system is supported, often improving eye movement as well. The earlier the treatment, the more time and effort are saved in preventing cranial deformation.
