Sorry, it might be a silly question but we have never had a nanny. We are thinking of hiring one for a few hours but then we live in a rented house and cannot put locks wherever we want. I would not have liked a nanny/baby sitter to go through our documents, personal belongings. Also, I am so frighten of hiring one in general. How can I know the person is going to be a decent one and is not going to take indicent pictures of the kids or something else. All these stories make me paranoid to the nannies. Do I need a camera? I know they have to produce a certificate from police but then it does not guarantee anything. I hope I have not offended some good nannies :)
