I have a whole list of articles that indicate that conflicting info from
nurses to new moms has a negative effect on  BF.  I cited 9 articles  from
1973 to 1992 in my research.  There were others but they were the best and
showed  a consistent pattern of poor info   over 20 years.  That's what
bugs me so bad - 20, 30 years later and its the same old same old stupid
poor info being given to naive, trusting mothers. Wish nurses would get
their act together! (I can say that - I'm a nurse).

a dr whose name escapes me at the moment has done the same sort of research
on other HCPs (drs and residents) inconsistent info  with sort of the same
results.  Gary Freed maybe.  Sincerely, Pat in SNJ
