Nathaie’s story went viral when she was born. Her dad, Andrew Jackson, is originally from Hull, England, and works for a software company in Sioux Falls, South Dakota. Her mom is an autopsy technician.

Concerned for her health, Andrew and Lacey sought medical reassurance. Natalie saw an ophthalmologist to ensure her vision wasn’t affected, visited a dermatologist and skin specialist, and even underwent an MRI.

It turned out that Natalie was born with Congenital Melanocytic Nevi (CMN). These are moles present at birth or that develop within the first few months of life. They are fairly common and, in most cases, do not cause any health problems.

Thankfully, all of Natalie’s results came back fine. While the dermatologist explained Natalie might face a slightly higher risk of melanoma, they assured the family it was just a birthmark and nothing to fear.

“Prior to her birth, we were completely unaware of this condition and the fact that she was one of the rare. She is even more rare considering her body has somehow lightened her nevus so much as well as eliminated the satellite nevi she was born with and no other satellites have shown up in her 4 short years. She is one of the fortunate,” Lacey wrote a few years ago.
