EBF and Green, Slimy BM

Mika
I understand that green BM isn't always a problem, but it started today with lots of white, slimy mucous. She has been fussy as well, which never happens. She is 2 months old. Anyone have any advice or suggestions? Should we wait it out a few days? I don't want to be an over anxious mother and rush to the dr. I'm trying to figure out if I'm overreacting. FTM here. TIA!
