as for brushing teeth, i think you must brush .. if not after 1mth i'm afriad you'll have tooth decay... maybe use warm water to rinse away the toothpaste instead of tap water???
mind me asking, who's doing confinement for you??
dont get too stress okay?? confinement is a very critical period for a mummy... dont let yourself get into post-natal depression.. Cheer Up!!! =D
