I would have to agree with norfolkbabe.
If something was to go wrong, that picture would stay with your child for life. Or she could get really distressed because you were in pain, and she couldnt help you.
My daughter cried at me on crutches on monday, let alone that lol. I know all kids are different, but you wouldn't want to see your daughter getting upset, that would distract you and then you might not be able to concentrate for feeling like crap for making the wrong descision for you all as a family. I think 3 is a little young. Its around this age that they remember their "first" memory when they are adults, I know I wouldn't want my daughter visualing me in complete agony or midwfies running around me and baby.
But it is your choice, and I am sorry if my opinion is abit strong lol. xx
