Look I don't think I can stick it out for another couple of years to get him *almost* sleeping through. There's no way I'd do cc now, as he's only 4 months but I'm not against it down the track if it's what he needs to get him sleeping alone. I haven't slept in the same bed as my husband for four months and it's taking its toll. Worse still, I think I'm actually doing my son a disservice by continuing this for much longer. He wakes hourly through the night looking for boob to get himself back to sleep. It's keeping both of us up. Not to mention I can't take him anywhere for too long during the day (eg friend's house) as he won't lie down to sleep on his own.
As far as sleep school goes, I've had friends who went and said it was the best thing they ever did. They won't do cc for young babies and my friend said there was only a little bit of crying involved for her one year old.
I guess I just want to hear from someone who broke the habit successfully and relatively quickly.
