I have my first class tomorrow evening too I'm having twins and want to do this as naturally as possible (both are still head down today confirmed by OB yay!) so we're still on for natural delivery. I know some things i can't have already (my water birth went out the window!) but the longer i can put off the epidural they would really like me to have (in case of baby B suddenly turning or going into distress) the better, scary and exciting that it's come to this time already
