My LO is 6 months old, and he has dark spots on his butt, back, and shoulders. They are Mongolian spots -- benign, flat, congenital birthmark blue-ish in color that is prevalent among East Asians, Polynesians, Native Americans, and East Africans. My little sister had it as a baby too, and it took a few years before the spots went away. According to wiki, it is normal for it to take 3-5 years to disappear.

The mother in me is worried about what other people will think of his Mongolian spots as he gets older. Will people think that the spots are bruises and assume that we are abusive parents? Will kids point out the spots and make fun of him?

Have you heard of Mongolian spots? Does your LO have a birth mark in a unique place?
