Even one of the best, fastest, and most complex pre-programmed signals analyzers in the world can't accurately distinguish between "stressed, sleepy, annoyed, bored, wet, or hungry," even after years of training. They're claiming this $40 device can?
I think the claims are hyped.
As far as the babies themselves are concerned, there's only one condition: "Something's wrong." Admittedly, the tone of that "something's wrong" cry is different depending on whether the baby is tired or just ticked off, so at least a couple of the product claims are theoretically possibly.
My concern is if parents attempt to use it to justify ignoring a baby's crying if it's not "wet or hungry," figuring the baby will eventually move on from stressed to sleepy, or bored to content with being bored, if not just tired out from crying.
Regardless, what if the monitor is wrong and the parents allow their judgement to be supplanted by an only partially correct, $40 monitor, even to the point of neglect? Will the courts allow the parents' neglect to also fall on the shoulders of the company who made the monitor and sold it to be correct?
Or does it behoove parents to use their "best, fastest, and most complex pre-programmed signals analyzers in the world" to put their feet on the floor and walk into their children's bedrooms, check the diaper and hunger, and even then, if the child is still crying, to simply hold them in their arms for a while?
