She certainly is. And it's not just the family Shelbie brings joy to. Anyone who spends time with her takes away something.
The risks of Vicki having a child with trisomy 9p are about 1 in 4. But Vicki loves kids and always wanted a big family. Some might see it as selfish because they think the child would have no quality of life. The truth is, they have a different quality of life. Shelbie will never walk or talk but she has her own way of communicating and she has a smile that can melt anyone. If Vicki did have another child with the same condition she would just get on with it and deal with it in the same way she has with Shelbie...though I think Cienna will be the last one....this time!
