In a message Jan B. wrote in response to Kathy D:

<< For urinating though, the mother would hold the baby out away from her and
make soft whistling sound through her teeth at which cue, said baby would
urinate.  No diapers; and no mother ever wet or defecated on.>>

So, maybe this partially explains the ability of baby boys to produce that
inevitable fountain of youth we see as soon as he feels that cool air when the
diaper is removed?
