We haven't tried it, but from what I have heard the main thing is to choose the right time (you are well, baby is well, no major upheavals are expected) and then persevere no matter what. Because if you cc for three nights and then change your mind, she will just learn that it takes three nights of screaming to get you to do what she wants, ie, give up on the idea. So if you're not sure, it's better not to do it. If you do go ahead, some support is essential. If Mick can't/won't help at night, maybe he can take over for an hour in the early morning so you can have a rest, or perhaps somebody else could come around and let you have an afternoon rest during the day?
