Congratulations!! Susbo has a ton of great info above and was one of the sources I used when making my decision. If it brings you comfort, I was told there was no need for a high risk ob/monitoring based on my pouch.
I had two uncomplicated vaginal deliveries before my pouch so I was an excellent candidate for a vaginal delivery. Ultimately, I decided to go the c-section route because we knew it was our last child, I had gotten the experience of a vaginal delivery, etc. Keep in mind that a lot of the research GI's are going off of can be outdated. If you'd like to explore a vaginal delivery (particularly if you'll want more kids as mentioned above) don't be deterred and interview some docs who have dealt with jpouch patients before!!
