How Long until I forget ...

As I watch a women birth naturally on TLC's A Baby Story, I can still remember very distinctly how bad it hurt when the baby's head was making its way through the birth canal. I remember feeling each contraction intensely - until they doubled up and it just continued to burn without reprieve. It is one of those pains Id like to say you will "never forget" - but thats not true. I will forget. I know I will, because I forgot until I was in the delivery room for the 2nd time the pain that I had felt with Kalina. This time I just wonder, how long will it take this time to forget again??? Will I ever fall ill with baby fever again after that pain?
