I have read about this method somewhere and am not sure just how it differs from controlled crying - perhaps there is someone out there who tried it?
DD seems to need a good scream before she falls asleep but I really hate leaving her to cry. Sometimes she does settle herself within 10 minutes of half-hearted crying (which I can cope with) but recently we had a few days of absolute hysteria (no matter whether I was trying to soothe her or not)
