I remember hearing that the primary reason for the change in water/fat content through a feed was not a matter of different milk being produced. The milk as it is produced is always high in fat. The milk that accumulates between feedings draws fluid from the circulation to maintain a balance of concentrations across the cell membranes resulting in the first milk being higher in volume but lower in fat. As the percentage of "immediately produced" milk increases, so does the fat content. If this scenario is true, then it would stand to reason that the shorter the interval between feedings, the higher the fat content of the next feeding. I don't recall where I heard this explanation. Does anyone have a reference? Do I have it right or have I distorted what I heard in the time since I heard it?
