Hi
Although I am not an expert I have followed the jaundice issue
for many years.  I was recently glad to find out about
the following:
The AAP discourages the interruption of breastfeeding in
healthy term newborns and encourages continued and frequent
tfeeding (at least 8 to 10 times in 24 hours)... Supplementing
nursing with water or dextrose water does not lower the
bilirubin level in jaundiced , healthy, breastfeeding infants"
American Academy of Pediatrics, Subcommittee on Hyperbilirunemia
Practice parameter:  Management of hyperbilirunemia in the
healthy term newborn.
Pediatrics. 94(4) 558-565, Oct. 1994.

There is a lot of new info supporting continued breastfeeding.

American Academy of Pediatrics and American College of Obstetricians
and Gynecologists:  Guidelines for Perinatal Care (3rd Ed).
AAAP:  Elk Grove Village, Ill 204, 206-207, 1992

Martinez JC, Maisels MJ, Otheguy et al.
Hyperbilirunemia in the breastfed newborn:  a controlled
trial of four interventions.  Pediatrics 912) 470 - 473

subversive sources all! (just joking)  I haven't read
all of the originals yet
