Unlike the sensors attached to astronauts' bodies, which could cause some discomfort to babies, these pajamas are made with the sensors woven into the fabric.
Have we gone a little overboard? maybe? I know the article says that 2500 babies die yearly because of SIDS in the US alone, and I don't want to be insensitive, but wiring babies to constantly monitor their heartbeat and respiration seems a bit too much. In fact, it just reminded me of an idea I had a few years back, that we should have a day every year that could be called "A day without electricity" or something like that. Nothing electronic or electrical would be used that day. We should rediscover (or remind or educate ourselves about) the world that we had not too long ago. Please note that I make my living working with computers.
