OOOHHkay. I am going out on a limb here.
I am a mom of a son who was born very small and passed away. I also have two other boys who were preemies. There is a real market for people who have lost preemies and newborns for realistic dolls that are the shape and size and have the general appearance of the child they lost. There is also a market for preemie dolls to represent the general size of a child that survived so they know how little they were and what a miracle they are (not that you don't want to cook and eat them when they pour your Diet Coke out on your keyboard. Happened yesterday).
I would not want a physical representation of the child I lost but some of the moms in my support group really feel better and are able to move on because of the dolls. I don't personally get it but I am not going to ever second guess a grieving mom in some of these situations.
Could this be creepy? Yea there is some creep value there alright. However if someone was grieving, well we all heal differently.
Just my two cents.
