@rockhopper72 Yeah this is exactly why I didn't seek parenting help from.. anywhere. Because everything is contradictory and absolute and poorly defined.
We had a LOT of parents insist to us sleep-training was a non-negotiable, and recommend we do it, completely unsolicited. People who had had success with it would often gloat about how "it was the hardest thing they had ever done" but the best possible thing they could have done for their child and themselves and that essentially we'd be fools and assholes not to try it. Some would point to certain strategies or books, others would simply shrug their shoulders and say "cry it out".
We only partially sleep-trained (and didn't retrain when she got sick and lost her sleep habits), but a lot of the initial strategies we tried simply didn't work. What worked for us was.. get baby sleepy enough, drop her in the crib, shut the door. I'd still have to pick her up when she woke up crying for morning boob, which varied depending on her needs. But really, in spite of the name, CIO didn't involve much crying at all, and didn't drag on and on and on like Ferber.
But yeah really frustrating that there's no way to talk about stuff when there's no consensus. I still remember when a pediatrician friend called me up to tell me about the wonders of sleep training and happened to mention, off-hand, that they were also doing baby-led weaning. I was like wow what the heck is that! She explained it just meant letting the baby signal solid readiness and just feed them what you are eating, and recommended me a website to find out more (which I never bothered visiting). I was like wow that sounds so easy! And it was, because we ended up taking that idea very literally. I only found out later there are entire compendiums of BLW strategies and how to cut specific foods etc and rules on what to do, what not to do, etc. All of which we were totally ignorant of...
