Worried about your baby’s head shape? Here’s what you need to know…
It’s normal for babies to develop a slightly flattened head after spending lots of time lying on their back. This is called flat head syndrome, and it comes in two types:
Plagiocephaly – One side of the head flattens, making it look uneven or asymmetrical. The ears may be misaligned, and the forehead might bulge slightly.
Brachycephaly – The back of the head flattens, making the head wider, sometimes causing the forehead to stick out.
Flat head syndrome affects about 1 in 5 babies, and in most cases, it’s not a cause for concern. It doesn’t affect brain development and usually improves naturally as your baby grows and starts moving more.
When Should You Seek Advice?
If you’re worried about your baby’s head shape or notice they have trouble turning their head, speak to your GP or health visitor. They can check your baby and suggest helpful tips.
What Can You Do to Help?
Give your baby tummy time during the day.
Switch between a sling, sloping chair, and flat surface to reduce pressure on one area.
Move toys and mobiles to encourage head turning.
Alternate sides when feeding and carrying.
Limit time in car seats and prams when possible.
