Confinement nanny duties

Hi experienced mummies who hired a confinement nanny, I’ll be delivering in a few months time and currently preparing for the baby and confinement nanny which I had engaged few months back. May I know what are the duties of a confinement nanny? Does she sleeps with the baby at night? What are the household chores will she help out with? And also, do they wash their clothes and undergarments together with your clothes or separately? Thank you in advance! (: #pleasehelp #advicepls
