To convince my MIL...

When science presents findings that oppose tradition, how do we justify it? Last nite, my aunt recommended not to take ginger *gasp* during confinement as her ob said that ginger triggers jaundice. Told my MIL, and she's going to 'research' with a lady who's given birth many times. As for our personal research, here's what I found... Newborn Jaundice. Oh, ob said better dun take ginseng also (during pregnancy) coz got steriods. :P Dun like opposing MIL. Sigh.
