Farmergirl is right, that site is great. Dr Hale's book will explain with research references for your Pdoc. Seroquel has much much less than 1 percent of a dose transferred to an infant even in an worst case scenario (where infant would only feed at peak levels, which would never really happen).

Dr Hale's site also has a phone number available M-F. Most people do NOT have to quit breastfeeding. Even working in the neonatal ICU, the only mom that had to quit breastfeeding in the last year had a heart attack and needed very toxic meds to survive.

Good luck and I support you no matter what you choose to do!
