How Many Nannies Does OctoMom Need?


TMZ has learned 18 different nannies from the Merry Poppins to Order nanny agency have been looking after Nadya Suleman's family for the last two years -- before, during, and after the whole Angels in Waiting fiasco.

We're told the army of nannies work in 4-5 person shifts ... which could last up to 12 hours.

The nannies are each trained by Kaiser Permanente nurses -- and we're told Nadya pays for the services out of her own pocket ...

... probably with the allowance she got from Dr. Phil.
