A newborn's skin is prone to rashes of all sorts, but luckily most of theserashes are harmless and go away on their own.
Salmon patches (called a "stork bite" at the back of the neck or an "angel'skiss" between the eyes) are simple nests of blood vessels (probably caused bymaternal hormones) that fade on their own after a few weeks or months.Occasionally stork bites never go away.
After the first few days or weeks (or even months), new rashes can appear.Read more aboutnewborn's skin and rashes.
