Confinement Nanny - Yay or Nay?

Hi Ladies, as im approaching my 3rd trimester im having a lot of people ask me if we are getting a confinement nanny, or that we absolutely need one etc. My mum told me she got by all 3 kids without getting one, and my partner and i are sorta against strangers in our place for a month. Hes an amazing cook and will be taking the first month off when baby arrives. I guess my question is how essential is having a confinement nanny? And did any of you mummies not have one and got along just okay? Thk you!
