A newborn baby's skin can be prone to rashes, which can be a concern for new mums and dads.
Most of the time there's nothing to worry about, but if there are concerns, seek medical advice.
Common rashes in newborns
Pink pimples (neonatal acne) are often caused by exposure in the womb to maternal hormones. No treatment is needed, just time. They can last for weeks or even months on baby's skin.
Erythema toxicum is another common newborn rash that looks like mosquito bites or hives. Its cause is unknown, and it resolves without treatment after a few days or weeks.
Dry, peeling skin is often due to a baby being born a little late. The underlying skin is perfectly normal, soft, and moist.
Little white bumps on the nose and face (milia) are caused by blocked oil glands. When baby's oil glands enlarge and open up in a few days or weeks, the white bumps disappear.
Salmonpatches (called a "stork mark" at the back of the neck or an "angel's kiss" between the eyes) are simple nests of blood vessels (probably caused by maternal hormones) that fade on their own after a few weeks or months. Occasionally stork bites never go away.
Jaundice is a yellow colouration on your baby's skin and eyes. It is caused by an excess of bilirubin - a breakdown product of red blood cells. If the bilirubin level becomes sufficiently high, blue or white lights may be focused on the baby's skin to reduce the level, because excess bilirubin can sometimes pose a health hazard.
Mongolian spots are very common in any part of the body of dark-skinned babies. They are flat, grey-blue in colour (almost looking like a bruise), and can be small or large. They are caused by some pigment that didn't make it to the top layer when baby's skin was being formed. They are harmless and usually fade away by school age.
After the first few days or weeks (or even months), new rashes can appear.
