This is thought to represent sensitivity to estrogen, often left over from their time in the womb. Although more common earlier in infancy it can affect boys and girls, usually on both sides but not always. A pediatrician can tell the difference between this and worrisome things by exam. They would monitor this over several visits & it would be expected to fade over time.
