i found theatre very calm after labour ward. its all very relaxed
you can have your Dp/DH with you when you have your spinal put in if you want, but you will have to tell them thats what you want
i agree with all the pants commenst . i got large sized black ones from primark
i had my CS at 4.30pm and was "walking" at breakfast. not sore ( you still have drugs) but very scary and wobbly. its not a problem with getting teh feeling back, its just you have no stomach muscles left. IME getting into and out of bed and turning over in bed are teh worst things ater a cs
i went home that night as i hate hospitals, food, cheeky nurses, not getting baby to feed etc etc. i got a goody bag of lots of great drugs and my DH administerd them on a nursing rota. i love my home, good food round the clock and privacy to bleed all over the shower without being shouted at
i had a 18 month old and didnt pick him up for weeks. they can understand mummy has a sore tummy. i didn't pick him up in late pg either as i had a sore back
i am really anti social so got Dh to ban visitors for a week. he said it was on the consultants instructions as i came home so soon. Total lies but who cares, saves offending doting relatives. Remember teh older generation would have stayed in hospital for about 2 weeks and had the baby in a nursery at night so they coudl rest, even with a normal delivery
if YOU want visitors, then go ahead but on NO ACCOUNT get off the sofa or out of bed. do not answer door or make tea etc. you will have to have soemone with you anyway to watch your 2yo so let them entertain. and visitors can make their own coffee. get them to iron or vaccuum if they want to help
i admire those who say they were back to normal after 3 days but i certainly was not.i didnt pick up toddler for 6 weeks and was careful lifting other things. i felt " disabled" for about 4-6 weeks . i mean not able to do what i usually do. this annoyed me more than teh pain, which i had worried about beforehand ( see above comments on drugs) 
BTW you are not silly, its only normal to be worried, its major surgery and you have to recover AND look after a newborn at teh same time. be gentle with yourself and make sure your Dh pampers you.
