I didn't know what category to put this question in....

My EBF babies poops are frequently so dark green it's almost the color of cooked spinach. And sometimes it looks like it has cooked spinach in it. Other times its yellow or yellow brown.

I pump and bottle feed (mostly. We still bf occasionally), so I'm thinking it can't be a foremilk/hindmilk issue because I put whatever I pump from one breast into the bottle and she finishes it.

Is this still in the realm of normal? She doesn't seem to be particularly gassy or fussy, so I'm not really worried about health, just curious.
