We are going through this too for the past couple of weeks... growth spurt I guess? Plus just general fussiness & gassiness, and yes overstimulation! We usually have 2-3 hours of extreme fussiness in the evening, same time 7-10p. It's like clockwork! I haven't had any real consistent success with anything, I tend to just avoid making plans for that time (eating dinner ahead of time, for example) and spend that time cycling through nursing (with the unlatching/screaming/relatching of course), burping, diaper changing, walking around/swinging/bouncing/patting her, and Dad doing the football hold which sometimes works wonders. I know this isn't realistic for most mamas, especially with other kiddos! I love the idea of wearing baby to soothe, but Nora hates the wrap and gets pissed when she is wrapped/swaddled too tight... she wants to SPREAD OUT.
Tonight I had a small victory with gripe water producing a massive burp & then reintroducing her white noise app on the Bose which seems to have knocked her out. Not sure why we ever stopped using this - it was constantly on in our room for the first couple of weeks... then we kind of forgot about it.
