She had a lot of symptoms of oversupply at about 2 months, which is when we started investigating tongue tie, as well. The pulling off, letting milk run off, etc., decreased or went away after the tongue clipping. I can't say for sure that was directly related to the clip versus simple maturity, but it did stop, at least. She does gulp fast occasionally, and here and there I'll leak from one side while she's nursing on the other - but that's not common anymore (I never wear nursing pads, for instance). I'm not dealing with what feels like a huge supply - not a lot of fullness, etc.
Back when she was 2 months, I did try block feeding and pumping off foremilk. I also cut out dairy at that point (I'm off dairy, again, now, as well as soy). Her intestinal symptoms, which caused concern both for allergies as well as oversupply, improved in the week of doing those things - though the mucous returned before I reintro'd dairy, and she gained NOTHING that week, so I ditched it all. (I later realized I'd eaten edamame and that's what caused the major mucousy stools, not just dairy.) I haven't done anything else significant to address any possibly oversupply or over-active letdown issues, since then.
Oh, and she's got very, very slow weight gain, which is the biggest issue of all (though everyone agrees that she seems entirely healthy, so unless the digestive issues are a problem, we just think she's more petite than my boys). She's 7th percentile on CDC charts; just under 25th on WHO charts. She's 10mo and comfortably wearing 3-6m clothes.

I've tried to contact an LC that had tongue tie expertise (or so I read somewhere) in my area, but haven't heard back. I need to look again at who is around here and could be an option. I may have to drive to the other side of town, about an hour away, to find someone who can evaluate and give oral exercises. At least I've talked to those folks by phone and found them very helpful. Ah! They'll likely be at a baby/birth fair next week, so I will chat with them there, to start with.
Who would generally do a test of BM for staph? A GP? Pedi? LC? I'd never heard of a link with staph. Would it pose any risk for the baby?
Thanks for all your insight!
