Which side again?

  An idea though of while breast-feeding my 3 month old daughter....
  I sometimes forget which side I used last and generally it's when my daughter is hollering for food....
  So, I thought of a simple bracelet that can be worn by the mother which has a dial for L and R. Thus, this can be turned to whichever side was last used, saving the hassle of remembering at 2 in the morning!
  Health benefits include less risk of mastitis (means each side is used equally, rather than favouring one side) and less engorgement issues, for the same reason.
