Magic Baby Wishes

Charlotte this morning, holding a bottle of blue bath salts:  I wish for a new baby!
Me: Oh, you want another baby, Charlotte?
MC:  Yes! (rubbing the bottle with her hand) Is this a magic bottle?
Me: No, it isn't magic.
MC: Oh. I thought it was magic.
Me: But you want another baby?
MC: Yes! And then the new baby and the baby can fight!
Me: Oh, no! I don't want that.  I want them to be friends.
MC: Oh, then I don't want a new baby.

What?  What kind of child have I created?
