Darkening nipples when pregnant?

Fox • Lover of literature, art, minds, wonder, and the love of my life-my wife. 😄

So, my wife is about 18 weeks pregnant and her nipples have darkened and enlarged a little bit. I have no problem with this,I am just curious if this is typical and is it going to stay like this after she gives birth?

Also, they are more erogenous which she doesn't like touched any more because she feels she will get turned on When breastfeeding. Does that happen too? I don't know what to say to this.
