Green poop - can it be anything besides imbalance?

[Sk8ermaiden]

My baby (3 months old) was fed my pumped milk and supplemented with formula for her first 7 weeks. Most of her poops were golden, with one or two a day being green formula ones. It was very clear.

Now she is nursing (and she gets even more from the breast than the pump did - she's been weighed before/after) and we are supplementing with donor milk. This mom's milk has about 4x as much fat as mine does. Her poops are green or green/gold swirly. Sometimes they are very dark green like formula poops, but usually they are yellow-green.

I just don't understand. How, when she is getting more hindmilk than ever, have her poops turned green?

Any suggestions? Block feeding is not an option because she needs both breasts (and often a bottle after) at every feed.

I'm not sure what's causing it, but I was always told that if baby is happy, growing well and not having tummy issues than the colour of the poop (as long as it isn't blood) is not a problem.

Does baby have tummy issues? If not, the poop colour may not be an issue.

No, no tummy issues at all. And her growth slowed down a lot from what it was doing before, but still gaining even though it is less per day. As long as she keeps gaining I figure it can't be too bad.

Sometimes green poop can show a food intolerance, but I think sometimes it just happens. I'd watch baby as a whole before getting overly concerned about it.

Any chance she could be getting too much volume with each feed? Or too many calories with each feed (given the higher fat milk)? Both can cause green poos because her tummy will "dump" what it can't process along with some bile causing greenish poops.
