I once worked for family that would leave partially finished bottles of formula or sippy cups of milk lying around their home for days, and then "discover" the nasty mess and drop the containers of curdled milk in the sink for ME to deal with.

I told them, "If these are left for me to deal with, I will throw them away and go buy new bottles/cups when needed." Miraculously, they managed to stop leaving formula/milk to curdle every weekend.

I had already successfully convinced them that coming in on Monday at 7:30 am to an unutterably disgusting pig sty of a kitchen after I left at 5:30 pm Friday with the kitchen clean, was akin to me visiting their offices over the weekend and randomly throwing papers all over, spilling coffee on important files, and breaking all their pens. They stopped leaving the kitchen a filthy mess.

Great point made.

Thankfully, I have yet to work in a pig-stye, but have read a few horror stories online about nannies who have.

Some of my nanny family homes have had some disarray, however as long as the bathroom is clean, I am good.

I am not tough to please, I suppose.

How is nanny biz reviews an "expert"?
