If my daughter's experience is any indication she blew that theory right out
the window.  Jillian breastfed for 5 years and started signs of puberty
(breast development etc) at age 9.  Began having menstrual cycles at 12.

Deborah I loved your reply on what to tell the mom whose 2 week old is
sleeping through.  "Count your many blessings!"  Still smiling over that one,
