Baby birthmarks

One in three babies has a birthmark. Here are the facts about birthmarks.


Birthmarks are far from unusual, but their size and shape can vary hugely from baby to baby.


They are becomingly increasingly common, studies suggest, with low-birthweight babies more likely to have a birthmark.

Birthmarks are most likely to occur on the head and neck, although they can appear anywhere on the body. They are not always visible at birth – some will only appear a few weeks later.

Most birthmarks are harmless, but if you notice your child’s birthmark bleed, change shape or grow, consult your GP. Large or unsightly birthmarks can be treated with lasers to help them fade.

The main types of birthmark are as follows:

  • port-wine stain: dark red and permanent
  • strawberry mark: bright red and rasied, usually fades
  • cafe au lait: tan or light brown, permanent
  • congenital pigmented naevus: black/brown mole, permanent
  • salmon patch/storkmark/angel kiss: small and light pink, usually disappears
  • Mongolian blue spot: flat, irregular-shaped, blue in colour.
