I have a tiny white spot on my nipple which comes and goes, it has been there forever (appeared sometime after Jackson was about 12 months I think) and if I squeeze it (sorry if TMI!) it is like a whitehead pimple, a tiny solid white bit comes out of it.

Is this what a blocked milk duct is? and would it cause any problems with breastfeeding? It is not painful or anything, and is barely noticeable, the little white spot does get bigger if I don't squeeze it to get the lump out every couple of days.

Also I didn't continue breastfeeding with Jackson, I tried so hard for a couple of weeks, but was in excrutiating pain throughout a whole feed, and no one suggested it could have been thrush, which is what it seems like it was. This time My BB's are really leaky already, I am 25 weeks and have to wear breast pads, is it common to have better or early milk production the second time around?
