Maybe you are right... but a onesie that "knows that when a baby wakes up, the parents will, too -- so it turns on lights and music and even makes the coffee." ... is of no use to fight infant mortality.
The author also invokes 'helicopter parenting' as if it applies to taking care of babies. Helicopter parenting is when parents disrupt other caregivers during the care for their child, it has nothing to do with being sure about whether your baby is dying. I am confident parents themselves can configure and determine when and when not to wake up when their baby is awake.
As a non-parent, do parents really drink coffee in the middle of the night when their baby wakes up? That seems like a terrible idea..
"Angelcare voluntarily recalled 600,000 under-mattress sensor pads after two infants died of strangulation when the cord attached to the pad wrapped around their necks" - http://www.slate.com/articles/life/family/2014/02/mimo_and_o...
Strangulation by baby monitor is correlated with having a baby monitor.
Looks to me like a hell lot of problems added to what I would already have with the baby alone. My parents had me in their room and I survived. Others died. Maybe that's just the way it is.
The decline in SIDS over the last 2 decades tracks the education of parents not to put infants to sleep on their stomachs.
