Found in Breastfeeding Abstracts, Feb 96:
These references re breastfeeding with breast implants - both indicate no
obvious
contraindications to breastfeeding:
Berlin, C.   Silicone Breast Implants and Breastfeeding.  BREASTFEEDING
ABSTRACTS, 1996, 15(3),  p. 17 and
Levine, J., Lin, H., and Rowley, M.  Lack of autoantibody expression in
children born to mothers with silicone breast implants.  PEDIATRICS, 1996,
97: 243-254.

Also LLL puts out a booklet, I think, on the subject.
