Green poop

Jazminn
So I breastfeed at night but baby girl bottle feeds while I'm working and I've noticed that she's been having green poops more frequently than yellow poops. I try to leave her on my boob on each side until she wants to come off on her own just so she can get the hind milk but she tends to get so fidgety and makes me think that she's done. I'm trying to feed her as long as possible but is green poops normal to an extent? Is it because I'm bottle feeding more often now since I returned to work?
