Happy newborn with frothy green poop

TucktheTurtle

DD is a week and a half old, and most of her poops are green and frothy. She has the occasional yellow, seedy poop. She's not very fussy, doesn't seem to have gas problems, and doesn't spit up. I don't think I have an overactive let down, either. She poops and pees a lot, so I know she's getting enough. I usually feed her when my boobs start to get uncomfortable, about every 2-3 hours. 

Should I be concerned about green poops without any of the other symptoms of a foremilk/hindmilk imbalance?  I really don't want to screw up my supply.

What should I do?
