Dear Esther:
La Leche League International offers materials in many different
languages. You can see a list at:
http://www.lalecheleague.org/Lang/translations.html
It listed four inexpensive pamphlets on common breastfeeding concerns
as being available in Vietnamese.
At the top of the page, it also said that LLL is always looking for
translators, willing to work without copywrite restrictions. Any
talented bi-lingual Lactnetters out there?
Sincerely,
Margaret Wills
LLLL
