Where are all the parents who failed at sleep training?? I wanna hear your take

I’m always reading on here about parents who sleep trained and how it took only “2 days” or the baby only cried “max 20 minutes before falling asleep.” It’s really funny to me because my baby (luck of the draw, you know) will easily cry for hours if I just leave him in his crib. Drowsy but awake is offensive to him, and putting him in his crib when he’s comfy and sleepy will cause a brain-melting meltdown until he’s very much wide awake, lol.

It’s obviously genetic. I was apparently also a terrible sleeper as an infant/toddler and continue to be so.

Any neurospicy people on here who also think sleep training (even crying it out) is a scam?
