I certainly have more respect for someone who does sleep training because they think it's best for the child, rather than for themselves. Of course, everyone will say that's why they're doing it, but you seem sincere.

I still think you have to be misinformed or deliberately ignorant of the evidence that's out there to hold this position though. I also think the reason people don't dig deeper is that they, perhaps unconsciously, would rather not discover something that is uncomfortable and inconvenient for them.
