Prenatal Classes

Well, we finally went to our first prenatal classes, only because everyone was telling us it would be a very good idea to know what you're getting into. But do I really want to know how painful it is giving birth to a watermelon? Our instructor was very reassuring though and told us that it was going to be a wonderful experience, and that things usually go well as long as you RELAX! Apparently thats the hard part. She then proceeded to show us this PCV tubing that was 10cm in diameter. Thats how much you have to be dilated before they will let you have your baby... AHHH! thats enough to make me tense!
