So this is where we're at now: I have explained to my wife that she cannot come home and be alone with the kids. She initially realized that this was going to mean some sort of half-way house or something, but she's now latched on to the idea that I should hire a nanny to look after the kids, and then if she's drinking, the kids will be protected. If she tries to drive with them, the nanny could call the police, for example. I do not like this idea at all. It puts the nanny in an almost impossible position: Suppose my wife denies drinking and wants to take the kids to the shop. What is the nanny to do? Call 911 on her employer? But my wife seems to think it's fine, and that it's better for the kids than them being away from her for six months while she gets fixed up.
