Let me preface this by saying I am a man, and smoked a little too much, so I’m sitting here thinking… what is or was the original purpose of a bra? Weight support? Vanity? Covering the nips so people’s eyes met your eyes and you can have a normal conversation? Like what’s it all about?
Size of boobs has no bearing on milk production. We all have the same equipment in there, more or less, most of the difference in breast size is just fat. I never got big boobs while nursing and made so much milk, it’s made on demand when the baby nurses, not stored in the boobs!
