Lisa,
The most helpful book I have found on breastfeeding multiples is Karen
Gromada's "Mothering Multiples: Breastfeeding and Caring for Twins." It is
available from La Leche League, 111 pages in paperback. It is
knowledgeable, practical, and written in a caring and supportive way. I
encourage mothers who are contemplating breastfeeding twins to read it
while they are pregnant.
