Ignore all pics of celebrity mums who appear to have lost all their weight and have a baby who sleeps all the time - it isn't real!
For the first few days don't change out of your dressing gown - everyone will think that as you are dressed you are coping fine and ready to take on the world, the cooking and the housework.
If something goes wrong and there are problems with you or your baby, don't be afraid to ask the medical team as many questions as you want until you are satisfied you know what is going on. And if you don't understand, ask again but try and stay calm.
It isn't a competition, do things in your own time in your own way and don't compare yourself to other mums who appear to be coping better / have lost more weight - you'll only feel bad and you don't really know how what she is going through to appear like that (too tired to eat, has to cope because there is no one to help etc.) I had such a horrid time with my first, my second was a doddle - I'd have done the school run two days after the birth had it not been pouring with rain and I didnt' want to get wet!.
