here in colorado, and probably other places as well, i am told that the legal
guidelines for day care providers (or health department rules or some other
rules they feel obliged to follow) say that "milk" in a bottle must be
discarded after one hour. the milk they mean is formula. as i have pointed
out, that is an interesting rule, since the evidence seems to say that formula
at room temperature begins to develop unhealthy levels of bacteria after one
HALF hour, and as we know, breastmilk can be out, at room temperature, much
longer than that. instead of looking for research to back up the research you
know is correct, tell the mother with these guidelines, to ask the group who
published this information, where they got the backing for this
recommendation. it sounds like a mistake or misinterpretation or - what a
surprise - they think any milk given to a baby is - that other stuff.
