Thank you both for your replies! Lynn, it's so good to hear from you!! I've actually been trying to catch up on your posts.
We're doing a home birth, and my midwife actually teaches at conferences specifically on how to sew up tears, so I know if need be she'll be able to sew me up just fine...
I guess I'm just getting nervous. Looking at the size of a normal newborn compared to, well, myself, is quite daunting!!
