I found a site ages ago called http://www.ineedamommy.com . it has videos for sale on it where a Mommy figure regresses an adult baby,. the camera is at the point of view of the baby so when Mommy says you're going back into diapers for wetting the bed it feels like she's talking to you. there's even one where she magically shrinks you (I've been told there will be more). You can buy the DVD's or single clips or for around 20 dollers you can subscribe. It's 20 Dollars a month BUT you can download all the past videos (and there are LOADS) and they are yours to keep and you can cancel at any time easily (I accidental cancelled by forgetting to updating my card details when i got a new one)
I had a quick look on the forum here and can't find a mention of them, so I thought I'd share. Try the site, to be honest the free trailers alone are fun :)
