Yeah, she does sound gassy and uncomfortable, which is probably why she keeps rooting around for the paci as well. I don't really have any experience with that, burps always worked here, sorry. It sounds like there may be something to it though, if she's gassy, has smellier BMs, and you've got a forceful letdown. Maybe she's getting too much foremilk and not enough hind milk in the MOTN? (((Hugs))), also hoping it passes quick for you or you get something figured out.
