Hi, Kirsten: If you never able to determine why milk production has sharply dropped ( and there is no medical reason found) in this mom's left breast, so what? She is capable of fully meeting her baby's milk needs on just the right breast. I'm also a little confused as to why she is pumping to see how much she is getting. The fastest way to drive a nursing mom crazy is to have her do this. My philosophy is: As long as the baby is getting what he needs, is gaining weight appropriately, growing and developing normally on what they are doing breastfeeding, they are FINE! I'm working really hard with my moms to dispel the mistaken notion that breasts are exactly identical in size, shape, nipple size and shape, milk flow and milk production. Nothing could be further from the truth! Any body part that we have two of, is not identical - feet, hands, eyes, ears, and breasts, etc! In situations like these, my job as the LC is to offer massive amounts of support and encouragement. Remind this mom that she successfully nursed one baby - no reason to suspect she cannot also successfully nurse this one. I suspect this baby's nursing pattern is different from the first, which means he is stimulating her milk supply differently. And the observation the mom made with her left breast from her first experience, may mean that there is an anatomical reason for the milk production pattern she is observing. If this is indeed the case, there is nothing she can do about it (short of appearing on the TV show Extreme Makeover, LOL!). Just my 2 cents...
