After watching my wife give birth to our three children, I can't imagine the difficuliy that would have been added if she had been in restraints.  It seems not only good common sense to not restrain her while giving birth, but it also seems that it would be healthier for she and the baby as "mom" can reposition herself when necessary to "push" and move about to help the baby be born.

She has enough problems because she is incarcerated lets don't add to her burden!
