Mark.... is there any way you can get her to come "help" you give Ranger or Evan their fluids so she "gets the swing of it" even if it only means watching as you explain???? That might make her feel more comfortable when the time comes that she has to do it. Also, you can certainly let her know what signs to look for.... maybe type out a list for her to put on her fridge so she won't forget since several weeks or months may pass before she the symptoms start to appear. The sooner she notices, the better off Colby will be, but I know you know that.
