My new grandson has one!

This also occurs in some Polynesians.

Lamenites my arse.

My grandson has it too.

My two kids have them. I blame their mother

If you are refering to the dark spot in the lower back that in lighter skinned people looks like a bruise, both of my children had one.

Their mother was native american, confirmed haplo group D by DNA testing.

Oddly enough 90 percent of east asians and 80 percent of native american children develope this. In mixed races it is about 40 percent. I had never heard of it before and was relieved when my son's doctor explained it to me.

Both my kids had them at birth. My kids are half black / half white and it is common amongst mixed children. Dr. had to document them for years in their charts until they could no longer be seen to avoid them being mistaken as a bruise. They were unable to be seen by the time they were about 4 yrs old.

I have never heard of a Mongolian spot. Are you certain it isn't the result of a partial curse? Maybe a misfire punishment for being the son of Michael Cain?

Congratulations - your new grandson!

My 3 children all had it, which surprised us, as I'm a British Huguenot (mainly), and my wife is half French (Anjou), half Russian Jewish...

I can see where she got the gene from, but on my side, who knows?

I found it rather exciting.
