I know this seems counter-intuitive. But it only seems that way because people tend to immediately 'blame' poor gain on low milk production, or only low milk production, rather than looking at baby's ability to transfer milk- poor milk transfer will cause poor gain just as much as low production would! So, what you describe with weight loss would happen if for some reason, baby is unable to transfer milk efficiently.
Of course baby not gaining normally might also happen if mom is removing so much milk when pumping, there is not really enough milk "left" for baby when baby nurses. So when a mom is pumping as well as baby nursing lots, it might make sense to try to have pump output and supplements "match" more precisely. And this is probably most helpfully done if pump output is reduced to what baby actually needs in supplements, rather then increasing supplements to match pump output, because the goal (presumably, not every mom has the same goal) but the typical goal is more nursing and less pumping and supplementing.
Here are my thoughts on weight checks. One, is that since gain fluctuations, rather than steady gain, is the norm, daily weight checks are far too frequent and may be unduly concerning. It is hard because then what do you use for your guide? You have to use pees, poops (assuming baby IS still pooping daily, if not, then poops becomes not very reliable) behavior, and more or less, your intuition on a day to day basis, with accurate weight checks every...
