You know, Halloween is coming up. But, that would work if only they were voice activated and the eyes open and shut in response. Something that would make them really creepy. Otherwise, meh.
Also, I guess if your only reason for having a baby in the first place is to get attention then creepy fake babies are better than having real ones.
Further, I was once accused of making these scary things. I do not. I merely pointed them out once and somehow somebody on POE thought I made it. I like uncanny-valley facsimile babies even less than the real thing.
I discovered this subculture through a bizarre news item about police breaking into cars to save these lifelike dolls in England and Australia. Too bad it was rather dated.
Just about every related video is a wellspring of uncanny discomfort and occasional crazy.
