My daughter has dark green to blueish spots on back and buttocks since from the birth, previously I was told they’ll disappear with time but as she’s now 3 nd half years old, the spots are still there... what are these spots, why she’s such spots and how these spots go?

A. If The sports have not disappeared as of now than that could be either just the general birthmark kind of a thing or some allergy or something with the skin so to be more sure about it it would be better that you consult a skin specialist ones regarding the same as that way you’ll get a better knowledge about this thing
