My 8 year old DD has what I presume is a breast bud, a lump under one nipple which is quite sore to touch. She has had a couple of other signs of puberty, despite being a very skinny little fussy eater!
The thing is, the lump is visibly blue under there. Is that normal? It could be a vein, but looks more 'lumpish' and isn't easily recognisable as a vein.
Thanks in advance.
