Do nannies help you???

I generally find nannies useful, but I use them more for cooking and cleaning so my sims are free to take care of the kids. Or as a pinch hitter for some potty training or something like that. I usually don't bother with high chairs, just give serving of food directly to the toddler from the fridge myself, so don't need to worry about that. And I like them for kids actually cause they can help with homework or mentor and encourage so skills get built faster and certain aspiration requirements are easier to meet. But then, I often grab "free services" as soon as I can, so I don't have to pay them, so I'm not really losing anything by having them hang around in case they're useful. For my vampires, I sometimes keep them around just to feed on, lol.
