Flat head syndrome

Flat head syndrome

Sleep on his back and let him play on his tummy

Flat head syndrome can occur in the womb or can be caused by a baby sleeping, resting and playing in one position.

Many babies develop a flattened head when they are a few months old, usually from sleeping on their back. Flat head syndrome happens when the back or one side of the baby's head is squashed against a firm mattress for a long time, which eventually forces the soft bone of the skull to flatten.

It often corrects itself over time and is usually nothing to worry about.

The solution is not to change your baby's sleeping position from lying on their back at night. It is important for babies to sleep on their back as this reduces the risk of sudden infant death syndrome. Put your baby to sleep on their back and let them play on their tummy.

No treatment is normally needed. Your baby's skull should naturally correct itself over time. You can take some simple measures to take pressure off the flattened part of their head and encourage them to try different positions (see health visitor’s tips).

Health visitor's tips

Increase ‘tummy time’ - put your baby on their front to play.

Supervise them at all times and don’t let them fall asleep like this.

  • Get down to your baby’s level for face-to-face fun so they will enjoy lying on their tummy.
  • Use a sling to carry your baby upright so they are not always on their back in a car seat or pram.
  • Do lots of active play with your baby on your lap.
  • Change the position of toys and mobiles in their cot to encourage them to turn their head to the non-flattened side.
  • Don’t use a car seat except when travelling.

It may take 6-8 weeks before noticing any improvement.

I have heard about helmets that a baby can wear to help.

Their use is controversial, expensive and there is still not enough evidence to prove it will correct the problem.
