Just keep telling yourself that you are not going to get upset and react to anything she may say or do while she's there. B/c really, for her part.....it won't change a thing based on your reaction. That's why you have to look straight ahead and hold the hand of your child as you go.

It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
