Dear Cathy Liles,
You ask the hard questions!!  I wonder why she needs to define weaning so
tightly. I remember the first time the youngest cuddled to sleep instead of
nursing, but not the last time he nursed.  Ditto for the others, although I
can identify the month for all of them.  It's like trying to define the last
day of your period or the last day you had lochia after a birth.

Linda Smith, weaning from menstruation maybe?
