Re: Green Poop
Green poop in and of itself isn't a problem. Green falls within the range of normal colors. It very well could be a function of oversupply, but the green foamy oversupply poops are usually only a concern when the baby is experiencing excessive gassiness and discomfort. I would stay the course if your only concern is poop color and baby seems happy. You can try offering the same breast for two feedings then switching sides, but I probably wouldn't get too aggressive with block feeding because you've dealt with low supply before and don't want to return to that. Nursing on the one breast per feeding may work if you give it a little more time.
I definitely wouldn't pump. That will only make things worse. Pumping tells your body to make more milk, so eventually you need to pump more, which makes for more milk, and so on.
