I had my c/s at 3pm Monday afternoon and I left hospital on Saturday morning.
They were happy for me to go earlier but I wanted to stay as long as possible - mainly because we have a huge flight of stairs inside our house and I had a two year old at home that constantly wanted to be picked up. So I basically just stayed there and enjoyed my new bub for as long as I could.
There's no way I could have left the day after mine, no way!
