or what I should do to be healtier, happier, smarter etc?
never mind media scaremongering, but my MIL just does my head in
her latest gem is: vaccines are stored in mercury so DD, who's just had MMR and is poorly, should have a bath with bicarb of soda to flush the toxins out!
No, just NOOOOOOOO! 
even if any of that is/would be true I don't want a fucking lecture! I'm exhausted and was not asking for advice!
why can't she just say "yes, staying up till for with a feverish whimpering baby sucks"
AIBU? am I?
