Hi, at around 6 weeks old I noticed a patch that looks Like a bruise kind of a circle shape with a little blue/grey spot on the left side of the patch on his lower back/buttocks but the images I have looked at online don’t usually have just one patch and one spot where the spot is on top of the patch on the side. I was wondering if anyone else has this similar one that looks like this? my baby is half Caucasian and half Indian But it was not documented at birth and Im not sure it was there at birth I am worried to mention to the Gp as it says it can be mistaken for a bruise what to do? And if anyone thinks this is a Mongolian blue spot and has a similar one that sounds like this description thanks.
