moma2eli, that's one thing I was worried about. My dd nipple is about.twice the size of the other one, especially when it gets hard.
Mine are different...ones bigger and shaped different which makes my nipples different and my son would only take to one nipple and I didn't produce much milk in the only one he would take to...so I had to resort to formula:(
I definitely don't think I'll have an issue producing milk since I've been leaking colostrum for a couple weeks now, just curious if it would make a difference :) I have to remember to write it in my book to ask my doctor when I go back!
My sister has the same thing only one is an A and the other a D. She didn't produce any milk. I'm not saying that is the norm by any means just sharing my knowledge from my sis similar experience
I wouldn't think it would make a drastic change in your milk supply, they'll fill out to how much they need. :)
