Re: Oversupply now with decreased weight gain. What to do?
Oay, first of all I see no reason to be concerned about her weight. She's more or less hovering around the 50th percentile, and has been since birth. (See chart: http://kellymom.com/images/growth/growthcharts.gif). In the last month or so she's dropped down a bit, which is typical for breastfed babies in the 4-6 month range- as they become more mobile and devote more calories to things like kicking, reaching, rolling, pre-crawling, etc., they tend to lean out and drop a few percentiles. (For example, my own kids went from the 95-99th percentile at 2-3 months to the 75-85th range at 4-6 months.). If your doc still uses the outdated charts for formula-fed babies, your LO may appear to be dropping percentiles faster than she really is, because formula-fed babies tend to increase their rate of weight gain as they get older, while breastfed babies do the opposite.
Aside from green poops, what evidence of oversupply/OALD are you seeing right now? The reason I ask is that generally babies whose moms have OS/OALD gain weight quite quickly, and at this point your LO seems to be slowing down a bit. It may be time to transition to feeding on both breasts at a feeding, or at least shorten up your blocks. When a baby seems hungry and unsatisfied after finishing one breast, it's often a sign that she now needs both breasts when she nurses.
One thing you should not worry about is that a diet high in so-called "foremilk" is causing your baby to not gain weight. OS/OALD tends to result in very rapid weight gain, despite the fact that baby's diet consists of a higher proportion of lower-fat (but not low fat or no-fat!) milk. In general, when a baby has trouble gaining weight what matters is not the quality of mom's milk, but the quantity. And babies whose moms have OS/OALD tend to get a very high quantity.
