My original post was misunderstood because I used the phrase "it is almost creepy". However, the point I was trying to make is that many adoptive parents are specifically looking to adopt older children, sibling groups or disabled children. These children are often less likely to be adopted so government subsidies and services for these children are easier to obtain. For people who aren't wealthy but desperately seek to adopt children, these "marginalized" children are a desirable group. The subsidies make adopting possible for parents who otherwise couldn't afford it.
In short, the general public assumes that disabled children are very hard to place for adoption. For a small percentage of potential adoptive people this would be true. But unknown to the general public, there are many prospective adoptive parents who specifically seek a disabled child to adopt. For instance, I know one blind couple who wanted to adopt a blind child. They felt they had something extra that they could offer such a child since they were blind themselves.
My experience in the adoption field is that by the time a couple gets to the point where they are committing to becoming adoptive parents, they aren't very likely to insist on only a health, Caucasian infant. I know one couple who said they were willing to adopt a disable, inter-racial child. They got matched with an amazing child - such an amazing child they said they felt so guilty because their child was such a gift of grace. So many people associate disabled with "burden". To some degree, that might be true. Adoption is never an easy road and adding a disability can make it even more complicated. However, many people are so pleasantly surprised to find how blessed they feel when living with a disabled person.
