> Citation needed? This is the sort of thing that people use to argue against sleep training, too, but I don’t believe much evidence has been found for that.
Indeed, I didn’t mean to imply that “if the offspring is completely deprived of adequate touch or if the infant or toddler experiences only violent or painful touch stimuli” (to quote one of those) then things would be fine. Honestly, maybe I’m generalizing unfairly, but I’d be surprised if that outcome was likely from the parents that buy a Snoo. Maybe it’s a fair thing to warn buyers about. But sleep deprivation among parents presents massive risks both short term and long.
Sorry – I didn't mean to imply that using a Snoo is bad! Many cultures have used different forms of rocking cribs for ages, I'm sure it's absolutely fine if used with a bit of discretion.
