Debra and others, The amount of milk taken out is less important than the amount LEFT IN the breast. Retained milk signals the cells to adjust the rate of making milk - the message seems to be "she's not using what you're making, so slow down already." Less retained milk in the alveoli says "pour on the gas, let's get some milk made so she doesn't run out." According to Hartmann's new research with breast imaging, the storage capacity of the breast has something to do with this, as breasts that can store a lot of milk will perform differently than breasts than are drained every time the baby nurses. Based on my understanding of his research which corroborates what I've seen in my 25 years of experience, leaking isn't terribly relevant to supply either way. And supply is easy to increase by more thorough emptying of the breast by baby or another means. Dont' sweat the milk supply. It's the easiest part to get right. Getting the milk transfer part (the baby at breast part) is the harder part of fixing BF problems. Linda Smith, BSE, FACCE, IBCLC Dayton OH where it's 3 degrees Farenheit and sunny.
