I work for a company that helps adults with development disabilities live out their lives in as much comfort as we can provide. It seemed like an obvious choice given my own difficulties. So, what I can say about the women with Down Syndrome that I serve is that they tend to like things soft and things bright (although many are seizure sensitive and we have to be careful). The two most popular with the women are stuffed animals, no matter the age, and things like crystals or a fish tank with a fish in it. Coloring books are also awesome for them, but that is best given as an add on. But, once again, this depends on their degree of function. Given that she is NV, she would be very regressed on the emotional spectrum, so think very very young. I hope I was able to help as much as I can given that I don't know her. And good luck, I am sure she will love whatever you give her, because it's from you
