I've tried pupd when he was tiny after reading BW which says nothing about what age it is appropriate from. It didn't work of course. And I'm not trying it ever again as I just know it won't work.
I sometimes feed him to sleep and put him down. Sometimes he wakes up sometimes he doesn't. Sometimes I put him down wide awake and shh/pat to sleep. He normally would have a dummy then.
I have gone through a phase of religiously putting him down awake or at least sleepy and he would then fall asleep on his own with me just sitting beside him. No difference whatsoever.
I think how they fall asleep is really irrelevant. They either sleep or they don't. End of.
I'm just feeling so deflated by the lack of any progress. The only progress he made since he was a newborn is that he can actually sleep not on me. That's it. But back then at least naps were better... even if only in my arms.
On average he wakes up 6 times a night. A good night is 4 wake ups. 8 on a bad night, which by far is not the limit. Half of those wake ups seem to be just because. Which none of the books, sleep websites etc. address. They just assume you feed to sleep every time, so once you stop, they should stop waking up. Well, I don't feed him every time. He still wakes up.
