NPC Nanny Career
Description

Like all my careers this requires the XML Injector.
The nanny! Who can forget our beloved nanny? Well ... I never had a nanny growing up, but I did watch Marry Poppins and the Nanny on TV. So here's a full-fledged career to define the nanny NPC and to play as the Nanny character in a household! Of course your Nanny can't be the same as a household member due to filters and even if I took that out I don't think it would work anyway just like every other career ... other than the Grim Reaper.
The Nanny trait originally disabled aging, which I removed. I also opened it up to teens, like all my other careers and removed all trait-related and location filters. But I'd also like to note that the trait also prevents stressed and uncomfortable buffs which is VERY overpowered. I guess that's why nannies are more effective than regular Sims at taking care of kids.
Anyway, with this you can make a terrible Nanny who hates kids and change their work outfit (a MUST for me with most of these) or make her into a robot (which is what I did, obviously).
