I just had my 2nd csection and this recovery has been so, so much easier than my first. I totally could ride in a car 10 hours at 2 weeks pp, probably not at 1 week though. Following my first csection I wouldn't have even wanted to ride in a car that long at like 6 weeks pp. Not sure why one recovery was so much easier but I think it just varies a lot person to person as well.
This. My 2nd csection recovery has been a breeze. We did just travel in the car 7 hours at 1 1/2 weeks PP for XMas and the trip was absolutely fine!
