My daughter is almost 14 weeks old, exclusively breast feed. Her poop has always been the typical yellow mustard poop. She started daycare two weeks ago and since then it is almost always green. She is still only getting breast milk, mostly fresh that I pumped the day before. Rarely frozen milk. I know green poop can be a sign of too much fore milk but I always pump until milk stops coming out so I don’t think I’m just pumping fore milk. And it’s like this even in the weekends when she is breast feeding only. Any thoughts? She isn’t acting any different so it doesn’t seem to be a problem I guess ?
