Is there anything intrinsically unhygienic about fresh baby poo (or pee?) I find myself much quicker to put something in the washing machine if it has been poo'ed on than other body fluids. Is this just conditioning? Surely breastmilk and dribble are just as liable to harbour developing bacteria?
Maybe to complete the picture I should add fresh adult poo and pee to the spectrum, but reckon that the argument for relaxing about those is lost before it's begun because they are more smelly.
Suppose sick, blood and sperm ought to go in the mix too.
Yum!
