That has to be a hard one you knowing he isn't ready. Is there any chance you would reveal the medication? Many moms and doctors (surprisingly) think a mom needs to wean to take meds that they really don't need to wean for. If you don't feel comfortable saying the name, take a look at this website and do a search for the name of the medication. This man has done so much research and written multiple updated books. It would help any nursing mama be sure the medication she needs to take won't hurt her baby.
