hmmm, it depends... in my experience the green poops (which were frequent, watery and foamy with a lot of gas, red butt and major "colic") were NOT normal and assoc with my hyperlactation syndrome or foremilk hindmilk imbalance.. so I think it depends on if your guys have other symptoms and if you do.. in our house green poop is a very bad thing.... don't know if it applies to you guys.....
