Joan:
I am so sorry you are feeling frustrated. It must be hard to have the scale wiggle on you like that!
When I did LAWL after my first baby, that would hapen to me about every two months or so. Not sure why, but it always worked itself out. I believe that if you continue doing what you are doing, being POP, the scale will have to start moving again. Hang in there and keep your head up, girl!
