You will remember the English nanny who actually murdered the son of a prominate couple a few years ago. That was when I learned about nanny recordings that people were putting into their homes to check up on what 's going on at home while they were at work. Lots of abuse was discovered! I cannot imagine hiring someone over the net to look after my child, regardless of how much he or she came recommended by the go-betweens.
I think some American couples like to refer to their babysitter as a "nanny" anyway. Makes them feel like they're hiring someone superior while they are thinking of themselves as being among the "aristocracy."
My granddaughter will be going to a pre-school that allows her parents to view what's going on at the site via the internet when she's about three. It's a bit more expensive than other care centers in the Lubbock area, but well worth it.
