First off, HUGE congrats!!
Tip #1 - Bring a pillow for your stomach for the drive home. Hold it into your stomach esp if the road is familiar and you know where the bumps are. If your husband is like mine, their "go slow" isn't THAT slow. You will feel the smallest of bumps on the road, press in firmly. I was given this tip and it was a godsend.
We all recover at different speeds, take your time and let your husband do as much as possible. There are no medals for being supermom and over doing it. If it hurts, stop. It it feels ok, take it handy.
I personally recovered from my section quicker than natural. I was sick for over 6 months after havin DD natural, 50+ stitches and to this day still have a lot of issues. So ladies, even if you are a bit upset about not going natural, and not "feeling woman enough" thank your lucky stars that your hospital was sensible and professional enough to stop you going through what I went through. The "shame" you feel by going section, won't be to the same degree that I felt when I couldn't be more than 2 min away from a toilet for several months.
Stop for a minute, open your mind, learn. You may not agree with what I say, I may not agree with what you say but we will both learn something new.
