Stork bites occur in a significant number of newborns, with estimates ranging from to ; they are reported more frequently for white babies than for infants of other races. They result from a dilation of capillaries in the skin, and may become darker when the child cries or strains. The birthmarks, which are pinkish and irregularly shaped, occur most frequently on the nape of the neck; however, they are also common on the forehead, eyelids and upper lip. A baby may be born with a stork bite, or the birthmark may appear in the first months of life. They may also be found occasionally on other parts of the body. The skin is not thickened and feels no different from anywhere else on the body; the only difference is in appearance.
