A friend of mine had a c/s last week. She's a very healthy girl, who had a great pg, but is still struggling to walk from the brm to the kitchen (and her house is very small). I initially thought she'd recover quickly like some people do, but she's not.
Something her OB told her was, if you think you can do something, half it, and that's what you can actually do. You might think you can do more, but your body won't allow it.
Good luck!
