My son is 3 and still nursing.  I asked him yesterday if he got much milk
when we  nursed and he replied, "Sometimes yes, sometimes no."  I then
asked why he liked to nurse if he didn't get much milk.  He replied,
"Because I do."  When pressed for a reason he replied, "Because I like
chocolatey milk!"  Now, he has had, and does like, chocolate milk.  And I
do certainly eat chocolate.  But I decided then and there that there were
some things I didn't want to know....  ;-)

Linda V., who knows that's now how it works, but feels it could be a good
excuse to eat more chocolate! (Outside of Philadelphia Pennsylvania)
