Hi Julie,
Congratulations on your daughter's arrival and your full milk supply. If you want to, you can start to slowly wean off the domperidone at this point by following the instructions on this webpage:
http://www.asklenore.info/breastfeeding/induced_lactation/stopping_domperidone.htmlDomperidone is not recommended in pregnancy so our advice would be to wean off the domperidone before attempting to become pregnant again. Your baby will most likely start solid foods at 6 months of age and will likely require less milk from you at that point. So if you want to become pregnant, this would probably be the sort of time frame for making the attempt.
Warmest regards,
