it's a simple volume equation, the volume of milk grows exponentially with breasts, so does the amount of glands secreting milk   there's even a long term study done here in brazil that's worth mentioning here, which proved that breastfeeding for longer can increase iq of the baby   25449.amp of course, as you mentioned, it's a question regarding the right proportions, there's a point that the increase in tit size doesn't correlate with any gains to the offspring, but such a council of anons to decide which point it happens has yet to be formed, same i believe could be applied to hips, i've seen women as broad as a horse but i don't believe this should be the right course for reproducing, too little and your risk death on childbirth, too much and it hinders movement
