Braxton Hicks

I can not believe the amount of Braxton Hicks that I have been having! They feel like a tightening all around my belly and then he kicks like mad. Which is a good thing, although it does hurt when he does it non stop.
We had our Birthing From Within class last night and talked about labour and what to do when I "lose it" and feel like I can't take it anymore. Hopefully it won't be that bad...sometimes people make it seem like labour is the worst thing in the world....if that was the case why would people do it in the first place? And why would a woman go though it more than once???
