I have twin girls, and one of them has even nipples, one of them has uneven nipples. All three of the nipples that are the same size seem slightly swollen with a little lump underneath. The one nipple that is smaller than the other three has no lump and seems completely flat.
It hasnt always been like this, and I just noticed it. Im going to call my ped on Monday to ask, but what do you all think?
