I must be one of the few people who doesn't want the baby to come out early (or right on time)! I'm totally okay going 41 weeks, and I know 41+1 weeks is the average for first-time full-term pregnancies, so I'm definitely not getting my heart set on December 5 being the magic day or anything. I'm 36 weeks, and there are times when I feel a little uncomfortable but for the most part I'm good. The midwife hasn't done any internal exams to check for dilation -- I'd honestly be surprised if she did. And I know I would be freaking out (and not in a good way) if I found out I was already a little dilated and effaced at this point!
Mostly, I want the baby to be totally done baking before he or she comes out, and I'd feel a lot more comfortable that the baby was as healthy as he or she could be if he or she came around 40-42 weeks than 37-39. But another huge part is that DH is doing a lot of travel around the baby's due date -- luckily he has a break where he will home with no travel requirements for a week and a half immediately after the 5th. I won't be doing anything to try to encourage baby to come before 40 weeks, but after the 5th, I'll proably start trying some things to encourage the baby to come out before 42 weeks, when DH will be back on the road again for work.
