Even.. you know.. I have spent plenty of time around swimming pools.. many public swiming pools even.. and I have noticed with my plebian brain and poor eyesight that most swimmers get water in their mouths and spit it back out. This happens all day long at public swimming pools. There are chemicals in the water, like chlorine, that take care of most of that type of oral bacteria... yet.. if someone poops one little poop in the pool they evacuate it.
Common sense has dictated to my plebian brain that even the health dept has determined that there is a big difference between spit and poo. maybe you can give them a call and inquire as to what the difference is RAZD.
If they gasp and laugh at you as if you are a moron do not be surprised, even though you are not a moron. most young mothers would do the same concerning your suggestion that poo is as safe for a baby to eat as spit is to swallow.
common sense has dictated that to my plebian brain.
