Susan Carlson who spoke at an ILCA conference in '92 discussed the fact that while the "average" caloric content of human milk in the first few weeks was about 20 kcal/oz, it is 26 kcal/oz at about 4 months. Also, babies' energy needs decrease as they get older, and they aren't growing as quickly. There is a newer article out (can't quote chapter and verse right now) but it discusses the fact that a thin woman will produce a larger volume of milk with a lower fat content than a heavier woman who produces less milk but with a higher fat content. Now, if we are doing pre/post weights -- what happens? We get all excited when the thin woman's baby takes in -- oh, say, 4.5 ounces, but wonder askance at the heavy woman's baby who only takes in 3 ounces. Which is one of the reasons that ac/pc weights don't tell us everything. And if it is a thin woman with a small breast capacity who is trying to breastfeed on a schedule a la Ezzo -- then you end up with a baby who is not gaining well -- where as her Reubenesque friend who has a large storage capacity with higher fat milk does a lovely job nursing her baby every three to 3.5 hours, and wonders why there's a problem doing that. Lots of really really neat stuff -- a lot of which we don't know yet.
