Hey Tracy! I've had 2 c-sections and each one I felt different. But I sure would wantn't to check out of the hospital and go on a road trip with a brand new baby and a c-section.(The baby's doctor may put his foot down about taking the baby on a trip, I wouldn't be surprised if her ob-gyn would advise against it). You really are supposed to take it easy at least for the 1st 2weeks, I didn't with the second and was back in the doctor's office.Don't know how familiar you are with post delivery and not wanting to gross any of you non-moms out, but you do bleed after delivery(even with a c). At the hospital they give you the biggest honking pads you have ever seen. This goes on for about 2-4 weeks in most cases. Baby gets his first check up at 2 weeks and mom goes in at 6 weeks.
I think if your sister's attendance at your wedding is important to you, I think it's time for a family pow wow to look at your options
