i think the concept of breastfeeding is fairly straightforward, yes? no?
in middle school we spent a whole month learning about supply and demand in relation to the industrial revolution. you introduce a new product. it may take a while to get going. all of a sudden, demand is through the roof! demand has increased. so in return they will increase the supply to MEET THE DEMAND. but if consumers aren't demanding it they aren't going to make more. and conversely that's how you end up with oversupply, when the demand is high, you increase the supply, and then you have too many. is this moving too fast for you? because apparently it's moving too fast for some.
