I was a DD with my daughter the entire time I nursed. Then, once I weaned I went down to a D. With my son, I went down pretty quickly to a D (was a DD when my milk first came in). Now, since I’ve lost weight (down 20 lbs from pre-pregnancy weight), my boobs are even smaller and I suspect I’m a full C. I bought a new bra at 36D and realized there is a whole lotta room in there so I think I’ll be buying C’s from now on. I never thought I’d see a C again and boy am I happy about it!
Yeah I had 40 E when I started BFing and now at 1 year I'm down to a 36C. I'm so sad that I bought such nice quality nursing bra's early on(what a waste of cash) However I am ecstatic about my new shape.
my boob size stayed almost exactly the same until i got pregnant 8 months in. thats when my milk supply went down. (i was EPing) and when i completely stopped at 10 months, my boobs are just a tad bit smaller than pre-pregnancy - more of a deflated 34B as opposed to a nice, full 34B.
My boobs changed. I was a 36DD after my milk came in, and was down to a 32D at about 12 months. From that point mostly just my boobs shrank, until when I weaned my DD at 30 months I was a 32B/C. Even if you just lose weight your band size will probably change, so you should go to get re-fitted every few months just to check...
I was 34B/36B pre-pregnancy. When my millk came in, I went up to 40C, boy was I surprised! I got 3 nursing bras at 40C in the beginning and kept wearing them even though they became looser eventually. My favorites were nursing tanks with shelf bras - wore these daily for months. So I didn't have to worry about sizing so much.
My DD is now 17 mo and nursing 1-2x per day, and my weight is almost back to pre-preg (darn those last 5 lbs!). I wear my pre-pregnancy bras again fine.
I'm almost 5 months PP and got back to my prepreg weight about a month ago (I'm on a restricted diet b/c of her food intolerances, working from home and taking care of dd). Pre preg I was a loose 34B and by 20 weeks I was a 36D, which jumped to DD when my milk came in. As of a month ago, I am a 34C. Keep in mind DD is still EBF and has gained weight great the whole time.
