Yes, sorry, me.
I've written about it before, partly because I think it's important to give 'the other side of the story'.
We tried cc for 5 nights when DS was about 19 months or so, it was hell, it didn't even come close to working.
That said, I know one mum in real life who did it for 2 solid weeks before seeing any results.
I wasn't prepared to do that, but I managed to cope with the sleep deprivation.
DS is 2.6 and still needs us for 30 mins to an hour while he falls asleep, and then once or twice in the night. I co-sleep with him after he wakes up in the night, which helps me to cope.
If you go down that route, I'd say that most people see results within 3-4 nights, and experience 'angry' rather than 'hysterical' crying from their LO.
I promise, it's obvious if it isn't working.
And although I felt rotten about doing that to DS at the time, he has had no lasting ill effects at all. I felt it was something I had to at least try, because sleep deprivation is awful for everyone. You have my absolute sympathy.
