Megan - thanks heaps for the info. I actually had such a crap night last night that I woke up determined to do something about it, and what I had planned was basically what you described! Anyway, she has gone down for all her naps today in her bed, though it took about half an hour each time, and I had to stay with her - I wasn't able to leave her to cry except for once at the beginning. My intention is to work up to that over the coming days as she gets more used to being in the bed awake. She actually had an hour and half nap this arvy which is unheard of. Tonight took longer, about an hour of alternating settling, sleeping, crying until she finally stayed asleep. I guess the test is how we both go during the night! But with DH away for two out of every three weeks, I just can't afford to not get some decent sleep as there's no-one to give me even a short extra sleep now and then.
I'm interested to know where this method comes from exactly, and whether you know the one for babies over 6m?
