They occur in around 80% of Asians, and 80% to 85% of Native American infants. Approximately 90% of Polynesians and Micronesians are born with slate grey nevus, as are about 46% of children in Latin America, where they are associated with non-European descent. These spots also appear on 5–10% of babies of full Caucasian descent. African American babies have slate grey nevus at a frequencies of 90% to 96%.

    Both my son and daughter had Mongolian spots when they were really young.

    The daycare my son goes to pulled me aside one afternoon while I was picking him up and accused me of hitting him. They thought the mogoilian spots he had on his arse were bruises from me hitting him.

    I told them, no they are in fact moglian spots, and him being part asian means it’s a very common thing.

    I got up her for not having noticed this before. My son had been going to the same place with the same workers since he was 6 months old, he was 3 when they thought it was bashing him. This woman and her co-workers would have changed his nappy 100’s of times.

    What’s wild is us humans are stripped and spotted, like cows, but you can only see it in ultraviolet.

    They’re called Blaschko’s lines and they’re invisible to our eyes.

      This is false information, and easily found to be so. Just searching “blaschko lines uv light” gives several results saying it’s not true, and that there is never a source for that information in the articles, videos etc. that say it. It should also be obvious it’s not true just by most people’s experience, seeing people under UV light, via everything from clubs, movies, art, etc. isn’t rare at all, and you never see these lines.

      Check anything you say before doing so, we are all bombarded with misinformation from malicious intent already, no need to pile onto that with misinformation from ignorance.
