Positional plagiocephaly - this is when the shape of the head is flat in one or more spots.

Q. What causes flattening of a babies head?
A. Sometimes it's caused by lack of room in the womb, so twins, or a small pelvis or womb can be contributing factors.
Wryneck or Torticollis is another cause. This is when one or more of the neck muscles is tight so the head is restricted in it's range of movements.
Prematurity can contribute as the bones of a new baby increase almost tenfold in firmness in the last few weeks of pregnancy.
Back sleeping. Since it's recommended that baby's sleep on their backs to reduce the risk of cot death there has been an increase in the numbers of infants seen with flat heads.
Carseats, carriers and swings. In these devices the back of the head is resting against a very firm surface. If infants are allowed to spend a lot of time in them eg sleeping it accentuates the problem.

Q. Is there anything else that can cause a flat head?
A. There are a small number of other, less common causes eg premature closure of a fontanelle. Always ask us or your GP if you are worried about your baby's head shape.

Q. What can I do to prevent or treat it?
A. Frequent repositioning of your infant's head will help. Alternate the position of toys in the cot and the direction you lie your baby. Do not let them sleep for too long in a carrier seat or swing.
Regular tummy time when your baby has supervised time lying on their stomach. Ask us for the tummy time leaflet.
If you are worried at all ask us for advice, we may refer your baby for physiotherapy if we feel this is appropriate.

Q. Will it resolve?
A. Yes. The vast majority of infants will have the problem resolve on it's own over time if parents follow the suggestions and advice. Sometimes a head shape may be inherited. A flattening of the head in positional plagiocephaly doesnot affect the growth of the babies brain.
