Have finally (fingers crossed and holding thumbs) got rid of evil cold stew and microwaved fishfingers nanny. She hasn't worked for me since February, I paid her her final month's salary today.
DD1 says she never wants to see her again but won't be drawn as to why (just gets upset). DD2 hasn't mentioned her since she left.
It has cost me lots of money we don't really have to get rid of her. But it has been worth every penny.
