I have a couple of theories about what might be going on. I'm very suspicious of an allergy and will begin an elimination diet to see if that helps. (She has mucousy stools, chronic snuffly nose, occasional tummy pain, relatively light silent reflux, occasional random rashes, etc.) I am also curious as to whether she might have a bit of tongue tie. (She has a shallow latch, though it no longer hurts most of the time; she releases her latch over and over while nursing [spilling tons of milk out]; possibly making some clicking, but not sure; I can feel the frenulum where supposedly it should be smooth; I suspect my eldest and I have it, as well; etc.)
I've been weighing her here at home the last couple of days to try to see what's going on. I don't have a baby scale but have a postal scale that weighs down to tenths of ounces. I'm wondering if these patterns look normal. Anyone have input?
Friday evening, weighed her at 10 pounds, 0 ounces.
Saturday evening, weighed her at 10 pounds, 1.5 ounces.
Sunday evening, weighed her at 10 pounds, 0.5 ounces.
Then, she had a short nursing (sleepy and all that, having nursed some shortly before). Then she weighed in at 10-2.5, so she took in 2 ounces. She wet her diaper and weighed 10-1.5 after that. She nursed again and wet again and weighed 10-2. Again nursed and had a wet diaper and weighed 10-2.5.
So it looks like she's getting a net gain of half an ounce per nursing (and these are frequent nursings, every half an hour or so, not every two hours). Is that normal? Should I expect her to take in more than two ounces per feeding when she's nursing this frequently? I really don't feel like I have any supply issues (tons of leakage, can collect a couple of ounces *without* pumping from the non-nursing side with a Milkies collector, can feel quite full, and she not only nurses to contentment but also wastes a TON of milk by opening her mouth and letting it all pour out).
We're taking her in, probably tomorrow, to recheck her weight at the pediatrician. I know their scale is significantly off from my MW's scale (which caused a good bit of worry early on), but we're also comparing their readings to their readings, which is where it shows her falling significantly in percentile. I am also having my MW come and check her weight so I have a number to compare to her birth weight and 2 week weight on that scale. (Hoping to do both on the same day so I have some idea of how different the scales are at this point!)
I am indebted for any input anyone can offer at this point as I try to sort out what's going on and make wise decisions for our sweet girl! She is a remarkably happy, content, and quiet little one, and I would not have suspected her having any issues (okay, except for all the allergy symptoms!) save for the concern of our pediatrician.









I always feed on one side only, and have been keeping her on the same side within an hour or so of her first having it. Of course, then there are times like tonight when she's nursed no less than six times in the last 2-3 hours (including sleeping for a stretch in there), and I get rather sore and have to switch it up.
According to that link I'd been reading, that means a definite problem. Of course, the weird thing is we've seen our MW, pediatrician, AND an ENT (she has a 3mm mass on her inner lower lip which the ENT thinks is an enlarged/irritated salivary gland). No one has remarked on her frenula. But, I know that's also not uncommon to miss. So I'll be asking tomorrow when we see pedi and MW.



I really appreciate all the help and advice.
