I love horror movies etc. but how could you do that to baby dolls, they are babies afterall no matter if they are fake. You don't mess around with kids that way. It's just not right and you both seem like in your in this for the money.
One known rule out there is you dont mess with what you dont want to happen to you. So be arefull when you decide to have kids you will most likly get what you put in.
