Obviously there is no "right" answer for every woman with a pouch. You seem to be aware that there is an increased risk of incontinence if you decide to have vaginal deliveries. If you think that risk is worth it to have your babies vaginally/naturally than you have your answer. C-sections can be limiting to the number of kids you have and can cause more scar tissue that may cause health issues and blockages down the road. Always do what makes you feel most comfortable, but as most IBD suffers know, it's important to be prepared for that c-section in case it is needed. Congratulations on your pregnancy!
