Hi J.,
I am a nanny myself and on my last job interview, my employers brought with them a long questionary that they found online and they asked me very specific question about my childhood, how I would react to some situations, personal information, they requested references, they also did a background check (this is very important!).
When you find the right person, please make sure that you tell them what you expect from them.
Your baby is very precious, and you want someone that you can trust 100%.
Good luck.
If you need more hints, you can email me at ____@____.com
