I've been speaking to several mothers who quote this New York Times article about infant's health:
There is a bacteria, B. Infantis, which has gone missing in most babies in the industrialized world because of anti-biotics and the lack of breast feeding. It has been present for all of human history, but once missing babies are subject to all kinds of bacterial diseases because other bacteria can thrive in its absence. One of the common symptoms is creamy, diarrhea-like poops.
The mothers I've spoken to say after a few days of supplementation of B. Infantis, the poops look more brown and solid and their babies get happier. Anyone have experience with this? Amazon seems to have a variety of probiotics that contain B. infantis but it's hard to make sense or the reviews.
