Someone asked about green BMs a day or two ago and I haven't seen a reply, so here goes: When a mother describes green BMs I ask about her nursing technique.Very often she is taking the baby off the first breast after a certain time instead of letting baby finish. This can cause green stools. Michael Woolridge has done some research on this topic. I seem to get a lot of calls from mothers of fussy, unhappy babies who also have explosive, sometimes green BMs. This simple technique (finishing one side before offering the other) makes a big difference in most of them. One mother described it as "like having a new baby." I'd certainly look at this first before getting worried about other causes.
