Positional head-flattening is sometimes referred to as flat head in babies. Its medical name is positional plagiocephaly.
Positional head-flattening may occur in a baby who spends too much time lying on the same part of their head.
Sometimes babies are born with a slightly flat spot on their head. They may have head swelling or bruising from a difficult birth. These babies may be more at risk of developing a flat head.
How can I help to prevent positional head-flattening in my baby?
You can help to prevent a flat spot from occurring by varying your baby’s head position when you put your baby to bed.
You should always sleep your baby on their back, but from birth you should try to turn their head to a different side at each sleep.
If you find that your baby favours a particular head or neck position, it may be because they have a tight neck muscle on one side, preventing them from turning their head. The muscle is called the sternomastoid muscle. The tightness of this muscle can cause your baby to prefer turning their head and neck to one particular side. The tightness may prevent your baby from turning the other way. These babies may need physiotherapy.
You should check with your GP (general practitioner) if you have any questions or concerns.
