Positional plagiocephaly, or flat head syndrome, is a flat area on one side or the back of a baby's head caused by lying in the same position for long periods. It is common, does not affect brain development and usually improves as the baby grows and spends more time upright.
Key takeaways
- Babies should still always sleep on their back.
- Tummy time and changing positions help prevent it.
- Helmets are not usually needed.
What you can do
- Give tummy time several times a day while your baby is awake.
- Alternate the end of the cot your baby's head is at, so they look in different directions.
- Limit time in car seats, bouncers and swings outside travel.
When to talk to your doctor
See your doctor if the flat area is getting worse, if your baby always turns their head to one side (possible torticollis), or if the head shape looks unusual in another way.
