Yeah I had similar feelings.
It's your birth and you should try not to worry to much about what everyone else thinks because everyone else isn't having your baby, you are

I tend to think it's a GOOD thing that your giving this some thought now. Too many people (and I was one) go into labour thinking they'll just wing it and see what happens at the time. I wish I'd thought more about this stuff BEFORE labour because my last birth in particular may have been very different.

You do what you feel you want to, this is your birth and no one should be making you feel a failure before it even happens
