You know, it's channel 4 strikes again, really, isn't it?
I am sure that the vast majority of people (ok, women, let's face it, there won't be any blokes, will there!) who collect these dolls just do exactly that - collect them.
People collect all sorts of things - kinder toys, stamps, buttons, thimbles, barbies....you name it, someone somewhere will be collecting it.
And collectors are all a bit obsessive, goes with the territory, but their reasons for collecting aren't sad and freaky and they have normal lives alongside their collection.
Sounds like channel 4 ..yet again ... went out there to find the few nutters and present them as typical of everyone who does it.
And I personally think those dolls are nasty and creepy, but I bet that most people who have them are not trying to recapture dead babies, relatives abroad, or live the best bits of parenthood without the inconvenient reality.
