Jennifer:

  you have summarized excellently.... thank you...

  the reality is there are many many issues just like this one. we often have
mother's tell us guidelines on many things that have no basis in research...
the list is probably very long and others may add but we can start with: you
must wear a bra 24 hrs a day, you must drink milk to make milk., you must eat
a bland diet...

  in the archives under myths you will find many more.
