@forreallife, we went all in.
We prepped for a week reading the book, listening to the audio book (because who has time to read!), and I wore a comforter toy. We then moved DS out of our room & the next to me cot, into his own bedroom & cot on the same night we started the plan. New room = new rules.
The first night he cried hard for 50 minutes and it was awful. But then he slept better than before. So we continued with the method through the fewer than normal night wakes and for his 1st nap the next day. But I've continued to use his 2nd and 3rd nap as pram naps to make sure he doesn't fall too far behind the recommended daily sleep amount. The 2nd night he cried for 40 minutes, then 30 the next and we're now on 15 to 20 and a much, much less intense cry, more a mumbling moan or quiet play with the comforter now.
During the day, I still feed twice each awake session because I think he needs it, but not within 45 mins of the end of the awake session. I'm still doing night feeds too. I first pushed him to 3 hours rather than 4 because I knew he could do 2+ during the day based on his napping. So I was more comfy doing this than the suggested 4 hours straight away. But then one night he slept through till 3.5 hours so from then I said I'd feed only every 3.5 hours, and again one night he slept longer so now we're on 4 hourly feeds, or less as requested. I do unlatch him, which I find very difficult to time correctly but have managed so far, somehow and he generally goes back to sleep even faster than bedtime, naps or other wakes.
I say all this and we're only on day 8 so it's still a work in progress with some nights better than others, but I was keen to share because sleep is so damn precious to everyone. I would suggest going all in too if you're all ready.
