I thought that DS (9mths) would never sleep through. I tried The NCSS book, then you-know-who was purchased, but i couldn't follow it all- went against my instincts really. I got to the point where i was planning CC. marked it on the calendar. the date passed, i kept finding reasons to not do it that weekend, then the next one and so on.
But DS is doing it on his own. He had a knock back with a stomach bug, then a cold and 3 teeth at once, but he's getting there without crying or strict routines or books about what we should do with him. He's just 'ready'. I stopped thinking of it as a sleep problem, and started thinking of it as a little person, struggling to learn a 100 things a day, not understanding that we have work, or that we can't nap in the day, and just needing our love.
This isn't a rant against CC or any other method- i understand making those choices. I just wanted to say that if you feel there's no hope, and they'll never sleep, they may just get there on their own.
I am so glad i didn't have the guts to do CC, because we didn't need it in the end. There's hope for all you sleepy parents out there, there really is!
