It sounds horrible, but I think you perhaps could take a look at why she is waking before you think about stopping it happening, you might find a better and simpler solution.
I don't like controlled crying because I think babies/toddlers have reasons for waking up, they're not just doing it out of habit/being annoying. They truly can;t help it and something is going on that means they need us.
have you checked her teeth - she could be getting her molars in and that's really sore. The main thing to remember is this WON'T be permanent. They nearly all have phases like this and it passes ,honestly it does and by doing CC you risk making a bad situation that will pass, into something worse that won't iyswim - it may not work, anyway, and if it does it could just as easily recur when something else happens like she gets a cold or the other children wake or whatever.
CC is rarely a solution, but cuddling her, waiting and making sure there isn't another factor going on - she could be not really awake but having night terrors or something - she could be in pain, she could be having nightmares, etc. is normally the way to go.
In any case if she is already distressed, as you say, when she wakes, that would indicate it would be a really bad course of action to leave her to cry at all - if you were going to advocate CC at all it would be for children who weren't actually distressed, just a bit wakeful/too tired/that sort of thing.
You would STOP if they became distressed so if she is waking very upset it's totally the wrong thing to do.
Sorry - I know you must be desperate. Is there any way you could sleep in wth the other kids while your DH has her in the bed to calm her down?
I co sleep with mine and he sleeps right through normally, though he wriggles - and this could be a great temporary solution, as she will get through this. GOOD LUCK but please don't do CC, it's not worth it, and might make matters worse.
