I have bought a extortionately expensive, guilt doll to open at the hospital, and a photo album with pictures in it of when she was a baby in hospital.
I have also bought a jigsaw, shopping list game, sticker books... but these are intended to give her sporadically at home to keep her busy when I am preoccupied. (and I never usually buy her stuff, honest!)
I will be adding chocolate buttons to my hospital present bag now tho!
