Emmam, I had a caesarean. She will be too busy with baby and the new life to be driven nuts I think. She will need lots of help with lifting baby.
Keep going up and down the stairs to a minimum, keep a changing set upstairs and one downstairs. Take it slowly, you think you're fine and then over do it slightly and the stitches/cut really doesnt thank you.
I went to Mothercare with hubby after I was out of hospital and walked slowly there from the car park, arrived in pain (longest walk I had done so far, and it is a very short distance!!) sat on bench whilst he shopped and hobbled back to car in agony. That was the thing that made me stop and think hang on, I've had surgery here!
Best advice I got was 'Granny Pants'! The big ones that come over your tummy and hips, the bigger the better, then they dont hurt or restrict your scar. Looked great on the washing line!
Take a special tape of music for theatre, that helped make it a bit more personal for me. Perhaps get her to take her Christmas Cards to do in hospital to while away the 5 days.
I found it very peculiar second time round going into hospital knowing I was having my baby that day, and walking into theatre. But it all went so well, and once the baby is out (and it takes no time at all) what does it matter. You're busy looking in awe at baby whilst they stitch you up, so it feels as though it takes no time at all. First 24 hrs you cant do much, but the nurses soon help you up and out of bed to the loo, you think you will never be able to walk again! You hate them at the time, but realise that walking little and often does help with the healing.
I had baby in bed with me for half of the first night, saved getting him in and out of the cot which I couldnt do, but it gets easier. There were other caesarian mothers in the ward, so those of us who had been in a while would help those who had just had their babies. Nice comraderie!
Final advice is take all the painkillers on offer, and with regard to the driving, they say if you feel you can manage a hard emergency stop then you should be OK. I could drive alright after 5-6 weeks, but before that I would have had fear of injury or pain if something difficult had arisen. It helped to drive hubbies car first as he has power steering.
Wish your friend lots of luck Emmam.
