40B prepregnancy, 40B during pregnancy, 40B breastfeeding...i had ZERO change during/after pregnancy and no engorgement BOTH times i breastfed...however, i also have Insufficient Glandular Tissue (IGT aka hypoplastic breasts or breast hypoplasia)...how lucky most of you ladies are!
How did they diagnose this if you don't mind me asking?
thats a reallly long story lol.
But it took a lot (mostly because most medical professionals dont know much about this condition, let alone even hearing of it

) But pretty much, i had a few lactation consultants after i had DS1 and was breastfeeding. I did EVERYTHING under the sun (EVERYTHING! I know more about increasing supply than any normal mother should lol) and nothing worked. I met with LC 4-5x per week for 2 months straight. No changes. I also have many of the markers for it (you lack breast tissue, breast are very widly spaced-more than 1.5inches, mine are 3.5inches apart, nipples are large, breast look like tubes/sacs, large nipples for breast size, very lopsided breasts (beyond the typical breast asymmetry), never having breast changes during pregnancy, no engorgment after the birth, etc. The biggest thing is primary lactation failure (after rolling out hormonal reasons, or birth experience as primary, etc). I got diagnosed a few months after i had DS1. I made less than 4oz (per 24 hours) at my MAX with DS1. I still BFed him until he weaned. Supplemented around 25oz per day with formula. Now i am BFing DS2 as well. Had another LC [this time] and all of that (an IBCLC to be more precise) and did EVERYTHING humanly possible, and yet again i have a severe milk supply issue. This time im making about 40% of his needs(you grow a little breast tissue during pregnancy, and i also took things like progesterone and goats rue to build more breast tissue). I supplement around 13oz per day with donor milk-found a lot of healing in IGT having donor milk, my baby is still fully breastfed even though i dont make enough and never will [it's a cold reality]
IGT sucks...the one thing that "everyone can do", the one thing that iim supposed to be able to do to have my children survive, i simply cannot do.

its heartbreaking in every way possible. Not to mention the emotions that run with feeling insecure about the way i look and that sort of thing (this goes way beyond wanting bigger breast....they seriously look like man-boobs- no joke

)...anyways...i wouldn't wish it on my biggest enemy

And its really hard not to get jealous or upset when women complain about their breast sizes. It's even more frustrating when ppl try to give you advice (most IGT moms are more knowledgeable than the majority of LCs out there) or act like IGT doesn't exist....its rough....sorry to ramble on and on

its just....well...a large part of life with BFing and all ATM.
