Obviously I have no idea what your daughter has. But my daughter was born with a few angel kisses, but they aren't on her face. Hers are much smaller than you describe and are scattered here or there along the edges of her hairline (she has super fine blonde hair, so they are easy to see) and the back of her neck along or just inside the hairline as well. When she was a baby, she tended to get extremely blotchy when she cried hard. To the point she almost looked like she has some sort of allergic reaction.
It scared me the first time she really cried because she was mad (not hunger cries), because that was the first time I really noticed how red and blotchy she became. I don't know, looking back on it, if it was the AK's that were dark or not... But, she is 10 yrs old now and she still has little spots. They never grew any bigger and most around the size of a pencil eraser, maybe a tad larger or smaller. They might have faded a little, but her skin is so fair that they are easily visible. Almost look like tan freckles now. We never pursued any treatment whatsoever because they are not on her face and they is no medical reason to do so.
