I have a daughter named Kiara. I have a foster daughter, soon to be adopted, called Cora. She is four. It is very confusing in our house! They both respond when either name is said. And my youngest kids don't talk very clearly and so we never know who they're talking about as they say both names the same.
First off, I see there is a Cora on the group. Would you think it'd be confusing with a Kiara as a sister, as well?
For the rest of you... what would you do in this situation? I try to call her Coco as a nickname, but now I've run into another thing I didn't think of... my 3 year old is called JoJo! LOL! So that's not working! I'd like to change her name to Tori upon adoption, it's similar enough, IMHO. I will talk with her about it next month and see what her thoughts are (can't really broach the subject with her until some more things happen legally...)
